With almost 20 years in business and thousands of successful projects undertaken, Cutting Edge Designs specialises in routing, trade signage, acrylic fabrication, panelling, wood and laser cutting, printing, 3D carving, finishing, assembly, and CAD design. Since its inception, the Newry-based company has been working closely with the cutting tool experts at Industrial Tooling Corporation (ITC) to complete an extraordinary number of high-profile projects.

Founded by David Hogg, Cutting Edge Designs was set up in a small room at the back of his family’s furniture business with a single CNC routing machine. Now, the company can take credit for designing, machining and delivering unique projects for some of the most recognised brands in the world. When the first Tekcel routing machine arrived more than 15 years ago, the company turned to ITC, not only for its cutting tools, but also the company’s technical support and service.

Commenting upon the Northern Ireland company’s journey, Hogg recalls: “Prior to starting the business, I worked at a sign-making factory that was using ITC cutting tools, so I was already aware of the range of products and services available. When Cutting Edge Designs started up, we immediately turned to ITC for their expertise and extensive product ranges. The supplier of our routing machines provided alternate cutting tools when we began and, like other cutting tools that we have tried down the years, none have matched the performance of ITC.”

The company machines a vast array of materials that range from wood, veneer, MDF, plastics, metals, rubber, composite and much more. For every project and every material, Sally Hunt from ITC has been on-hand with technical support.

“During the early years of our business, Sally was fantastic at providing technical support with regard to what tools we should use on specific materials, as well as the speeds and feeds required to optimise machining performance and eliminate vibration,” says Hogg. “Over the years, our ever-increasing expertise relies less upon this technical input. While it’s always important to have technical expertise from our cutting tool supplier, nowadays the key factor is service and supply. From this perspective, ITC always has cutting tools in stock, supplied with next-day delivery. This service is absolutely first class, and it is why ITC are the best cutting tool supplier in the industry.”

Regarding some of the projects and brands the company has worked with, the list includes names like Ferrari, Guinness, M&S, Liverpool Football Club, Subway and KFC, through to famous artists and sculptors, as well as TV and movie companies. Two prestigious projects the company has worked on include the Game of Thrones television series and the Burning Temple for artist David Best – all machined with ITC cutting tools. In Derry, there has been an annual tradition for more than 40 years of burning bonfires – and in the process, protestants, catholics and the IRA would leave both their weapons and grievances outside, enter with respect and greet each other – ready to move on.

Working with show organisers Artichoke and David Best, Cutting Edge Designs was commissioned to cut 16 designs, each in a large quantity with over 1500 parts being cut from many of the 8 x 4 ft sheets of birch wood. Employing all three of its routing machines to the project and a variation of ITC cutting tools, Cutting Edge Designs estimates more than 400,000 cuts took place in the project’s three-month timeframe.

Unlike the Burning Temple that, like its name suggests, was burnt to the ground, the small business also worked with HBO Studios and Tourism Ireland in the creation of beech wood doors for the sixth series of Game of Thrones. Again, ITC was integral to the project. Produced from trees downed by Storm Gertrude in a location known as the Dark Hedges, Cutting Edge Designs produced 10 doors with each one incorporating designs, iconic symbols and references from the episodes. Receiving the artwork and 3D models, the subcontractor converted the files into CAM models and applied ITC single-flute routing tools and its Tekcel router to the task.

“We decided on using an ITC 12 mm diameter ball-nose tool for our initial rough cutting,” explains Hogg. “This removed the excess material, making it easier and more efficient for the smaller tools to do the finer details. A 90° wood-cut angle was also implemented to prevent lifting or splitting of the wood along the grain. The rough-cut cycle took about 6 hours per door. Following this, we utilised ITC’s 3 mm diameter ball-nose cutter to achieve all the important finer details, machining with a step-over rate of 0.2 to 0.3 mm. This fine detail work took an average of 50 hours per door to complete. When each door was finish-machined, it was sanded and professionally stained by one of Game of Thrones’ set painters.

For the majority of the machining, Cutting Edge Designs applied ITC’s 180 Series of solid-carbide tools, as their ability to prolong tool life, perform at higher speeds and feeds, and reduce cycle times is a huge benefit. For finish-machining, the company applied ITC’s 180-1181-10-A-XL single-flute cutting tool, a 3 mm diameter tool that is said to demonstrate exceptional tool life and rigidity. These attributes are credit to its reinforced 6 mm diameter shank, 10 mm length of cut and 30° helix geometry produced from an ultra-wear resistant micro-grain carbide.

Concluding on the relationship with ITC, Hogg says: “The ITC tools perform exceptionally well: we use everything from routers and engraving tools through to ball-nose cutters, drills, compression spirals and special tools. The range is extremely diverse, the quality is unbeatable, and the service is a cut above anything from any other tooling company. Regardless of the material we are cutting, ITC has a tool and a solution for our business.”

Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has supplied precision subcontract specialist – NuMachine Ltd – with two new five-axis machining centres. The machines, a VCF 850LSR and a DVF 6500, are now in place at the company’s 10,000 sq ft facility in Hereford, where they are producing small-batch cast aluminium automotive components required by sister company, Coventry-based Sarginsons Industries.

Explains NuMachines’ managing director, Brandon Davies: “Although we’re an independent precision subcontract engineering company in our own right, some 30-40% of our business, year-on-year, derives from Sarginsons. The strong and mutually beneficial relationship between both companies has enabled us to build up significant in-house knowledge and expertise in machining lightweight components for those sectors served by Sarginsons, the automotive industry being particularly prevalent.

“As a company with a reputation for taking on difficult jobs we were approached by Sarginsons in 2020 to see if we could help them with a specific machining contract – one where their existing supplier was finding it difficult to meet the customer’s stringent quality and lead time requirements,” he continues. “Having looked at the parts in detail, it was clear that we would need new five-axis machining capacity to produce the parts in the quantities required.”

NuMachine is no stranger to Doosan machine tools or Mills CNC. As such, the company had, even before its most recent five-axis machining centre investments, four Doosan machine tools at its disposal – the most recent being a Puma 3100Y lathe and a large-capacity DNM 750 II vertical machining centre – both acquired in 2020.

Says Davies: “Doosan machine tools deliver great performance; they’re reliable and competitively-priced. The fact that they are supplied and backed by Mills CNC is a key determining factor as we believe that Mills’ aftersales services and its applications and technical support, are among the best in the Industry.”

He adds: “The strength of the Doosan-Mills CNC partnership was the main reason we approached them with our requirement for two new five-axis machining centres.”

Since being installed, the VCF 850LSR has been used to machine long, thin and asymmetrically-shaped B-pillars, while the DVF 6500 machines performance-critical front suspension mountings. The B-pillars and suspension mountings parts have complex profiles; they are machined to tight geometric tolerances and exacting surface finishes, and feature a number of intricate details such as thin walls, multiple cavities and blind holes.

To ensure that the parts’ structural integrities are maintained during machining, and to make job set-up and cycle times as productive and efficient as possible, both machines were supplied to NuMachine with innovative and highly-customised work-holding solutions that, prior to the machines’ delivery, had been designed, developed and proven out by Mills CNC at its campus facility in Leamington.

Says Davies: “Although the machines were installed at our facility in May 2021 – the project, in reality, began some months earlier and involved us working closely with Mills and a number of the company’s technical partners to design ‘best-in-class’ turnkey fixtures for both machines.”

The work holding designed for machining the left and right B-pillars clamps each part securely in place, enabling high-precision machining operations to occur without deformation. Each part, which is long, thin and curved, is held in place by two rotary tables and a trunnion plate. The part is rotated (indexed) 90° and locked to allow the machining of each of its four sides. Only one set up is required for all machining operations, and the same fixture can machine both the left and right B-pillars. An innovative feature of the work-holding solution is the ability to machine features through apertures and spaces designed in the trunnion plate.

“To ensure we could meet our customer’s lead times and to help keep costs down we needed one work-holding solution for machining both left and right parts, and to machine the parts in one hit,” explains Davies. “It was a tall order but Mills delivered the goods.”

It was a similar situation with the DVF 6500 and the machining of the left and right front suspension mountings.
“Specific issues that Mills had to take into account with the suspension mountings were the machining of blind and angled holes, and the use of 300 mm long tools,” he says. “The solution designed by Mills and its partners involves the use of three separate fixtures – one fixture each for completing first operations on the left and right suspension mountings, and the third [shared] fixture for undertaking second operations on both mountings. There are fixture changeovers required to machine these parts but, with practice, we have got these down to a fine art.”

Doosan’s VCF 850LSR is a large-capacity, travelling column-type five-axis machining centre with a tilting B-axis head. The head can rotate 110° on either side of vertical, enabling the VCF 850LSR to machine large and complex parts in a single set up. The machine also has a large working envelope: 3000 x 850 x 800 mm (X/Y/Z).

The machine supplied to NuMachine was equipped with the latest Heidenhain TNC 640 control, a 22 kW/ 12,000 rpm high-torque spindle, a 60-tool servo-driven ATC, linear scales on its X, Y and Z axes for high positional accuracy, and a touch spindle probe and 3D tool probe package.

Doosan’s DVF 6500 is a five-axis simultaneous machining centre equipped with an oil-cooled and directly-driven BT40 spindle, a 650 mm diameter direct-drive rotary tilting table with a 1000 kg maximum table load, a servo-driven ATC, roller LM guideways and integrated thermal compensation.

The machine supplied to NuMachine was also equipped with the Heidenhain TNC 640 control, as well as a 12,000 rpm spindle and a touch spindle probe and 3D tool probe package.

“The capacity and capabilities of both machines were exactly what we required for machining the automotive castings,” states Davies.

The arrival of the two new machines in May 2021 necessitated the craning in of both machines through the roof.
“The roof needed to be lifted and almost all our other machines needed to be moved or repositioned in order to site the two new Doosans,” says Davies. “Thankfully, this was all accomplished with minimal disruption thanks to Mills’ operations and logistics team.”

He concludes: “We’re a company committed to continuous improvement and the recent investment in the two Doosan five-axis machines is further evidence of this. By constantly investing in our people, equipment and processes, we’re determined to be the best we can possibly be.”

Two CMMs manufactured by LK Metrology have largely superseded the use of a pair of smaller capacity, 15-year-old machines in the inspection room at contract machining specialist WLR Precision Engineering of Wilford, Nottinghamshire. To enable production operators, as well as quality inspectors, to operate the new CMMs and access the measurement reports easily, the machines feature LK Launchpad, an icon-driven, touchscreen operator menu, and a network of viewing screens and tablets. The simplified operator menu lists all the available inspection programs and the exact component placement position on the machine table for inspection, giving operators the confidence to perform measurement tasks in just a few clicks. It is possible to share measured results and automatically generated reports between screens, tablets and other networked devices for easy access and viewing from any location.

WLR is widely regarded by its customers as an all-encompassing service provider, as in fulfilling virtually every contract it manages the entire production process. A proportion of the value of each part is rigorous metrology, often involving 100% inspection. Contracts come mainly from the oil and gas, pharmaceutical, medical, laboratory and scientific instrumentation industries, which place great reliance on the accuracy and consistency of parts delivered.

Sales manager Tom Parr says: “The increasing confidence that customers have in the accuracy and consistency of components they receive has resulted in us winning considerably more business in virtually every sector that we serve.”

What has helped above all in raising that level of confidence was the purchase in 2015 of the first LK CMM, an AlteraS 15.10.8 with a measuring volume of 1524 x 1016 x 813 mm. The machine quickly transformed quality control activities at the Wilford factory, making it faster, much more efficient and less labour-intensive in respect of both measuring parts and preparing inspection reports.

A major benefit of the CMM is its large table area, approximately 1.0 x 1.5 m, which is able to accept up to 12 identical components at a time for batch inspection, instead of just one as on either of the older CMMs. It is unusual within the manufacturing industry to see a measuring machine nested with multiple components in this way, but the subcontractor attests that it is a perfectly feasible way of operation. Typically, it is possible to inspect five batches during a day shift with a load time of about five minutes between each.

Once components are in place, an inspector presses a button to commence the measurement of every part in a single, automatic cycle, the longest of which is two hours. The operator is thus free to work elsewhere on other metrology equipment for a majority of the day. Efficiency is much increased compared with the former method, whereby an inspector was committed to sitting by a CMM all day loading each part individually prior to every automatic measurement cycle, all of which took an indeterminate amount of time that was longer than the equivalent automatic batch cycle.

With the previous metrology route, subsequently preparing reports by hand on 12 inspected parts would typically take three hours, which was not just time consuming, but tedious. Now, big savings are again evident due to the ability of CAMIO (CMM multi-sensor metrology software) to perform the task fully automatically. A comprehensive, graphically supported inspection report is available for an entire batch in a matter of minutes, covering perhaps 30 or 40 critical dimensions on each part, complete with colour-coded content in the event of any non-conformance. The software exports the data, via a CSV-type file especially formatted by WLR, directly into an Excel spreadsheet.

All these advantages have led to a considerable enhancement in inspection and reporting efficiency, allowing the subcontractor to accommodate a surge in orders.

By May 2021, the company required a further increase in batch measuring capacity. This time, WLR purchased a smaller LK AlteraS 10.10.8 with a working volume of 1016 x 1016 x 813 mm, together with the latest CAMIO 2021 and additional LK Launchpad software. The easy-to-use, graphical interface enables not only the two WLR quality inspectors and quality manager Tony Blood to load parts singly or in batches of up to six at a time, but also the 10 dayshift and five nightshift machine operators.

Launchpad makes it simple to load the correct program for inspecting a component, with details called up via simple graphical menus and icons on a screen positioned by the machine. The operator can locate the component by selecting the customer by name, or via the part category, or by directly calling up the part itself complete with details of the machining process. Set-up on the CMM is straightforward, assisted by 12 mm thick aluminium fixture plates pre-drilled with a grid of holes at a 50 mm pitch fitted across the granite table of the machine. The operator simply places the component in a numbered location on one of the fixture plates, as indicated by the Launchpad graphic, and instigates the measuring program by pressing a button on the touchscreen. Despite being a powerful process, WLR confirms that the software is remarkably flexible and easy to use.

For convenience, the same inspection results that appear on the screen adjacent to the machine are also available on networked tablets used by machinists on the shop floor.

Another plus point, introduced at the time the first LK CMM arrived, is the ability to program the machines directly from CAD. Before the new LK CMMs arrived, it was sometimes necessary to produce a first-off component for a customer in up to six operations on a succession of machine tools, then take the part repeatedly to the inspection department for measurement and subsequent correction if necessary. After it had been finished-machined, the component provided the basis for teaching a measuring program into one of the older CMMs. Now, in the same way that a CADCAM system derives a metal-cutting program directly from an electronic model of a customer’s component, the DMIS inspection cycle for the LK CMM can be created from the same CAD model using LK CAMIO software in advance of first part production.

All inspection routines for both LK CMMs are now prepared this way in CAMIO, which performs not just programming but analysis of the captured data and automatic reporting of the results. The measurement program enables the first-off part to be checked immediately on its first visit to the AlteraS 15.10.8. Programming time is quicker than before, but the biggest plus point is that it is completed offline, so the CMM is unoccupied, allowing inspection of components to continue uninterrupted. Together with the benefit of multi-sensor capability, permitting the use of a Renishaw SP25 scanning probe or a Nikon LC15Dx laser scanning head instead of a touch-trigger probe, measuring throughput has increased.

On the implementation of the successful metrology upgrade at WLR, Blood says: “Our new measuring processes can be used by personnel with a wide range of experience levels. The high degree of automation plus the ability to increase speed by scanning as well as touch-probing have helped us save time and remove inspection bottlenecks. Automation and deskilling of operations have also allowed us to enhance inspection efficiency without adding to our headcount. Added to this, every day there is a further economic advantage through the ability to run the CMMs unattended for up to two hours at the end of each day shift due to our strategy of batch loading.”

Parr adds: “The parts we produce typically range in size from about 5 mm square up to 115 mm in diameter by 250 mm long. At one end of the scale they are milled, turned, ground, spark-eroded and diamond-lapped from free cutting brass, aluminium and stainless steel, but very often they are machined from the toughest of alloys, including Inconel 718, Invar or Hastelloy.

“Consistently high precision is the watchword here, with machined tolerances normally of the order of ±25 µm, but exceptionally down to ±3 µm, if necessary,” he continues. “Nearly all components are inspected on our LK CMMs. There is enough spare capacity now to provide our customers with additional services if required.”

The KASTOlogic warehouse management system (WMS) and the KASTOlogic mobile intelligent app – two software solutions from industrial warehouse system manufacturer Kasto – are helping to streamline the operation of automated and manual storage areas at Schwarzwald-Eisenhandel GmbH & Co.KG (SchwarzwaldEisen). These advanced software solutions are allowing the steel stockholder to accelerate its processes, minimise error rate and track orders seamlessly.

SchwarzwaldEisen has become a leading steel distributor in the Baden-Württemberg state of southwest Germany, delivering approximately 120,000 tonnes of material per year. This fourth-generation, family-run company dates back to 1870. Since 1966, the headquarters has been located in Lahr and the company has since opened other facilities in Freiburg im Breisgau, Bad Säckingen and Karlsruhe. There are also subsidiaries at Rhineland-Palatinate in Germany, as well as in Switzerland.

Dr Steffen Marco Auer, who is joint managing director together with his brother Ingo Auer and Alexander Hatt, says: “We focus on organic growth and running a decentralised organisation. Instead of operating one major facility, we have several regional sites that are close to the customer, enabling fast and flexible deliveries. Efficient communication between the individual locations and well-organised logistics are essential for such an operation. That is why we structure all subsidiaries according to a similar principle and utilise proven and standardised technologies and processes across the sites.”

SchwarzwaldEisen uses Kasto as its preferred supplier of storage systems. For about eight years, an automated storage system from the UNICOMPACT 3.0 series has been providing the quick and efficient storage and retrieval of solid bar, tube and section up to 6 m in length at the company’s Lahr facility. The stockholder offers a range of materials consisting of around 10,000 products, mainly construction steel, stainless steel and aluminium.
Around 70-80% of orders for steel section are semi-processed to customers’ specifications using machine tools in Freiburg. For long stock, the Kasto system supplies material to two removal stations via an operating gantry crane offering short access times based on a material-to-operator principle. Sheet material is stored in a separate, manually operated area.

Auer outlines the challenges: “Our customers expect us to provide fast, error-free and trackable deliveries. To ensure this, we depend on a simple, clear and reliable control system for our entire material flow.”

SchwarzwaldEisen uses the eNVenta inventory management system (IMS) across all of its sites. The storage system in Lahr links to it via an interface created specifically for the purpose, as is the case for two other automated Kasto storage systems at Karlsruhe and Westerwald in Rhineland-Palatinate. This system ensures standardised order management and a high level of inventory transparency. The IMS transfers order data electronically to the KASTOlogic WMS, which in turn triggers the call up of required materials at the respective site. It is possible to track all processes seamlessly, virtually eliminating operational errors.

“In the past, our manually operated metal sheet warehouses required paper-based management,” says Auer. “It was not always easy to locate the required material in the long rows of shelves. Due to the broad product range, staff sometimes removed the wrong sheets or incorrect quantities and the customer did not always receive what was ordered.”

To integrate these storage areas into the intelligent electronic control system, Kasto engineers assessed the problem and developed a solution to display all storage areas in a standardised and consistent control format. One of the tools used was KASTOlogic mobile, a platform-independent, mobile version of KASTOlogic. This software makes it possible to use the essential functions of the WMS on mobile devices such as tablets and smartphones, independently from the UNICOMPACT’s operator panels.

The mobile facility is able to manage the UNICOMPACT automated storage system for long stock and, just as easily and flexibly, the manually operated metal sheet storage area. Warehouse staff have access to order and product data at any time. When removing sheets, the system directs the operator to the respective storage location and specifies the required quantity.

Each shelf has QR and bar codes. When an operator scans one with the mobile device, he or she receives confirmation of the material’s removal and a replenishment order is triggered if inventory is running low. All information is available both in the WMS and IMS via customised interfaces. The software system is scalable to include other sites as required.

Both the storage system and the control system can be serviced remotely. Kasto is able to access the software and clear malfunctions quickly and easily at any time. If necessary, a service engineer can be on-site from the supplier’s Achern headquarters at short notice.

“The concept is impressive in every aspect and we want to implement it at our other locations to help us become even more efficient across all of our sites,” concludes Auer. “If an ordered product is not in stock at a specific facility, it can be found in the system quickly and delivered from another site.”

”We believe that investment in the latest technology is the key to quality, reliability and competitiveness,” says Dave Zollo, joint owner of contract machinist IML (UK). He and Jerry Way started the business in 1995 and moved into the current 14,000 sq ft premises in Weymouth in 2011. One year later, the first sliding-head lathe arrived, a Citizen Cincom A32-VII with 32 mm bar capacity, followed in 2013 by a 16 mm bar model, a Cincom C16-VI.

These early investments were triggered by an increase in contracts from the medical industry and a desire to manufacture components in one hit, such as endoscope cleaning equipment parts. To cope with an ever increasing level of work, including for the high-end automotive sector which has grown over the past couple of years to represent more than 50% of turnover, there are now four different models of sliding-head lathe on site from the same supplier.

The latest two, designated L20-XLFV and L32-XLFV, were installed in 2018 and 2020. Unlike the first two Cincoms, they offer the flexibility to allow removal of the guide bush, as well as having the notable benefit of low-frequency vibration (LFV) software built into the operating system of the control. Zollo notes that the more modern machines are also more user-friendly, allow better access and are quicker and easier to set.

He explains: “These advanced, twin-spindle, sliding-head lathes are helping to keep us competitive on the world stage, as is automation throughout the factory. All of our lathes, including the four fixed-head models, are bar-fed and work 24/7, with the sliders able to accommodate a wide range of batch sizes from typically 50- to 30,000-off. The machines can easily hold dimensional tolerances of less than ± 10 µm.

“Even smaller quantities are economical to produce, partly because we have adopted a policy of standardising on one size of stock on each of the Cincoms, so we do not have to waste time changing over bar sets,” he continues. “We’ve also invested in automation on the milling side of our business, which accounts for more than half of turnover. Our four vertical machining centres are equipped with robotic loading and remote monitoring, while two horizontal machining centres on the shop floor have a twin automatic pallet changer to minimise idle times. It all helps to keep costs down and allows us to quote prices that are very similar to those we were charging two decades ago.”

Aluminium bar, which accounts for a significant proportion of the throughput of turn-milled parts, is the villain of the piece as regards sliding-head turning in the Weymouth factory. This material is often of variable quality in terms of straightness and diameter variation, so can jam in the guide bush of sliders and requires frequent supervision by the operator to adjust the collet.

The ability to remove the guide bush on the L20 and L32 in less than half an hour allows the subcontractor to turn aluminium bar into shorter components in fixed-head mode without problems. It also has the advantage of reducing the remnant length from typically 275 mm to 100 mm. The completion of one recent IML (UK) contract consumed 300 bars, so it is clear that a lot of material and money can be saved.

When turning difficult-to-chip materials, Citizen’s LFV software, which is part of the control’s operating system, breaks swarf into manageable chip sizes, whereas normally it would be stringy and entangle itself around the tool and component. This capability to manage the size of swarf is in addition to any chip-breaking features that may be ground into an indexable insert. Zollo singles out aluminium as well as stainless steel bar to be particularly problematic in terms of ‘bird’s nesting’.

To alleviate it, the LFV function can be switched on and off via G-codes in the part program, enabling optimal use of the feature during different parts of a cycle. It is, however, not a pecking macro in the CNC program itself. As one operator looks after the four sliding-head lathes, LFV is helpful in minimising periodic attendance at the machines to disentangle clogged swarf. It is notable that the eight-axis L32 has LFV on both the main and counter spindles, allowing the oscillations that produce the chip-breaking action to assist in the production of both front- and reverse-end turned, milled and drilled features.

LFV oscillation lifts the tool tip clear of the component surface by tens of microns for ultra-brief periods to allow coolant to penetrate the cut more efficiently. It reduces heat and prolongs cutter life, while at the same time enabling machinists to increase depth of cut, even when processing tough materials. LFV often eliminates the need for a roughing pass and significantly shortens cycle times. Zollo advises that it is of major benefit during attended day and night shifts, and especially so during the weekend when staff are not present.

He concludes: “Swarf build-up is really the only thing that stops modern bar-fed CNC lathes, which are inherently very reliable. LFV on the Citizen sliders virtually eliminates the hassle of clearing away swarf and consequent loss of production, especially during minimally attended operation. Even when we are running them unattended at the weekend, it is unusual for them to stop before the bar runs out. Should there be a problem, however, the on-board cameras allow us to monitor production and come into the factory if necessary to take remedial action.”
