VERICUT SUPPORTS PROCESS GAINS AT TRINITY PRECISION

An aerospace parts supplier in Wichita, Kansas, has built its business based on three key pillars: people, process and principle. VERICUT toolpath simulation and optimisation software from CGTech helps support the ‘process’ element of the company’s ethos.

Integrity and experience. Consistent performance. Clarity of purpose. These are words to live and work by, no matter the vocation. They are also the guiding philosophies behind Trinity Precision Inc’s motto of ‘people, process, principle’, and ever since founders David May, Steve Ford, Dave Tice and Chris VanNover opened the company’s doors in 2014, they have stood by them.

“When we started Trinity, it was important that we establish the foundations needed to ensure success for the company and its employees,” says VanNover, Trinity Precision’s vice president of operations. “One of these was the use of robust programming technology, which includes accurate, productive toolpath simulation. VERICUT has filled that role since day one.”

CNC programming manager Merritt Stuever has been at Trinity Precision for the past five years. Like VanNover and the rest of the company’s management team, he also has great respect for VERICUT. Including his time at Trinity Precision, he has been using the product for nearly two decades.

“After running a program through VERICUT, we’re not only assured that the G-code is consistent with a good part, but we also eliminate any chance of a crash,” he says.“Considering the cost of replacing a spindle and the machine downtime that comes with it, it’s a simple choice. VERICUT is a no-brainer.”

To say that Trinity Precision is heavy into aerospace work is an understatement. The company’s customer list includes blue-chip organisations like Boeing, Northrop Grumman, Gulfstream, Textron Aviation and many others besides. OEMs of this stature have zero tolerance for deviation in part quality or missed deliveries. As such, strict adherence to established processes is critical, which helps explain the aerospace supplier’s focus on ‘the three Ps’ in its logo, along with its reliance on sound programming procedures.

VanNover explains that Trinity Precision president David May purchased an existing “mom and pop” machine shop as a starting point for the new business. The previous owners were using a well-known brand of CAM software and had a single seat of CATIA from Dassault Systèmes that was gathering dust. May and his management team hit the reset button.

“We knew from previous experience that implementing change once you’ve reached a certain size can be difficult, so we took the opportunity early on to build everything right from the ground up,” he says. “We stayed with CATIA because that’s what most of our customers require and, like I said, we alsoinvested in VERICUT. It does everything that we need it to do, and seeing as we were looking forward to a lot of new CNC equipment back then, also liked the fact that we could develop our own machine tool models. It gives us a lot of flexibility.”

Today, Trinity Precision boasts 32,000 sq ft of manufacturing space and a fleet of advanced CNC machinery. The company has also enjoyed a four-fold revenue increase since those early days. VanNover notes that, like most in the aerospace industry, the pandemic-related slowdown in commercial aviation gave them “a pretty significant haircut” over the past two years. However, that tide appears to be turning and Trinity’s 70+ employees stand ready for future growth.

Of course, growth depends on robust processes, something Stuever and the rest of the engineering team spend their days developing. Every CNC machine tool has a standard tool list, greatly reducing set-up time and eliminating the chance that an operator will place a cutter in the wrong position.

In addition, all feedrates, cutting speeds and other machining parameters are similarly standardised within CATIA. Offline tool pre-setting is in active use at Trinity Precision and many of the machine tools employ tool breakage detection for automated operation. Every job goes through VERICUT before leaving the programming office, a requirement that Stuever says has saved the company countless hours of rework and even scrap.

“We’re mostly a high-mix, low-volume shop, so oftentimes we might have a couple of dozen new part numbers in a week,” he explains. “Since none of us can read and visualise hundreds of thousands oflines of G-code, VERICUT is the best way to check for interference, gouging, leftover material and any of the other everyday programming scenarios that can lead to a bad part or worse. And since we know the software will catch things like that, it makes the programming process both easier and faster.”

Stuever is also pleased with CGTech’s support level. He has taken several courses over the years and attended multiple VUE sessions (VERICUT Users’ Exchange). As a result, Stuever has come to know many of the people at the software developer’s Irvine headquarters.

“They’re very helpful and always take the time to make sure any issues or needs are resolved,” he says. “As far as technical support goes, there are only two companies that I rank extremely high. CGTech is one of them.”

VanNover offers similarly high praise: “The rest of the management team and I have worked in shops where machinists were out there changing programs, selecting their own tools and pretty much doing their own thing. However, you can’t operate like that anymore, especially with the available labour force. This is why we’ve taken most of that responsibility and put it in the programmer’s camp, making it critical that we have the right software tools. And so even from the very start, this was a non-negotiable aspect of our desire to lay the right foundation; VERICUT is a big part of that foundation.”

NEW VMC AND LATHE FROM MILLS CNC DRIVE 30% GROWTH IN TURNOVER AT PRECISION SUBCONTRACTOR

Mills CNC, the exclusive distributor of DN Solutions and Zayer machine tools in the UK and Ireland, has supplied Wordsley General Engineering with two new large-capacity machines.
The machines – a DNM 750 II vertical machining centre and a Puma 4100LB horizontal lathe – arrived at the company’s 2400sq ft Stourbridge machine shop facility in May and July 2023 respectively. They are the first DN Solutions’ machines the company has acquired in its 14-year history.

Wordsley General Engineering is a small precision subcontract company with a dynamic workforce and a reputation for achieving and delivering engineering excellence. Established in 2009 and today employing eight members of staff, the company provides high-quality machined components to a diverse range of customers operating in numerous UK industries. A specific strength the company is its fast and precise processing of precision subcontract components.

Machined from solid bar and billet, as well as castings and forgings, components machined by Wordsley General Engineering are typically complex in nature and feature tight tolerances and high surface finish requirements. The company machines these parts -usuallyfrom steel, stainless steelor aluminium – in small to medium volumes with batch sizes varying from one-offs (including prototypes and pre-production components) through to 500-off.

Wordsley General Engineering is a company committed to continuous improvement. It is passionate about delivering best-in-class machined components to its customers, on time and on budget. And, to ensure future growth and profitability, the business always looking at ways in which it can differentiate itself in the market and exploit new commercial opportunities.

Back in late 2022, with the disruption caused by pandemic firmly in its rear view mirror, Wordsley General Engineering made the strategic decision to strengthen its in-house milling capacity and capabilities by investing in a new machining centre.

Says Adam Tarbet, Wordsley General Engineering’s owner and managing director:“The objective was to invest in a new, large-capacity machine that would enable us to secure contracts, from new and existing customers. In particular, we’d be able to target the machining of larger-sized components that, in the past, would have been out of our reach. We did our homework on the size and specification of the new machine tool and, naturally, first approached our existing machining centre supplier.”

Believing that the response it received from this supplier was not particularly competitive, Wordsley General Engineering cast its net wider and, after discussions with employees, contacted Mills CNC.

“We had recently appointed a highly-experienced machinist who, in his previous employment, had worked on Doosan machines from Mills CNC and extolled the virtues of both,” says Tarbet. “Up to that point we always believed that machine manufactured by Doosan/DN Solutions were going to be expensive. However, after discussions with representatives from Mills CNC, we were pleasantly surprised with the new machine tool package they put together.”

The machine Mills CNC recommended to Wordsley General Engineering was a DN Solutions’ DNM 750 II, a large-capacity, three-axis vertical machining centre. This model features a 15.6kW/12,000rpm Big Plus spindle (165.5Nm), a 40-tool position ATC, a large worktable and aFANUC 0iTP control with 15” touchscreen iHMI.

Importantly, the DNM 750 II is fast and flexible and features 24-30m/min rapid traverse rates, linear guides, through-spindle-coolant capability and a spindle chiller. The model supplied to Wordsley Engineering also has a Nikken 260 fourth-axis unit for fast part indexing.

“The DNM 750 II is a heavy-duty machining centre”, explains Tarbet.“Its 1630 x 750mm worktable enables us to machine large components and/or smaller parts in a single set-up. Furthermore, its rigid design and build means we can ramp up speeds and feeds and take more aggressive depths of cut, when required, to help reduce cycle times and increase work throughput.”

According to Tarbet, the DNM 750 II, despite its recent arrival, has already had a dramatic impact on the company’s turnover, providing a 30% boost in less than six months.With such a positive experience of the machine tool technology available from DN Solutions, it was no surprise that Wordsley General Engineering approached Mills CNC when looking to improve its turning capabilities in June 2023.

“We contacted Mills CNC as we needed to increase our in-house turning capacity,” states Tarbet. “We were looking at investing in a proven, heavy-duty lathe with a large turning diameter and turning length.Following in-depth discussions with Mills CNC, we decided to invest in a new 15” chuck/116.5 mm bar capacity, box guideway Puma 4100LB.”

The FANUC-controlled Puma 4100LB provides Wordsley General Engineering with a significant increase in its turning capacity and capabilities. The lathe has a maximum turning diameter of 550mm and maximum turning length of 2092mm, and features a powerful, gearbox driven 26 kW/2000rpm spindle, a servo-driven 10-station turret and a hydraulic manual tailstock.The machine was also has a Filtermist mist extraction unit, vital when machining castings. It arrived at Wordsley General Engineering’s machine shop in July 2023, just four weeks after order placement.

To increase the machine’s productivity potential still further, Wordsley also ordered a SLU4X steady rest.In the near future, Mills CNC will retrofit an 18” chuck for even larger chucking work.

“The Puma 4100LB is a beast of a machine with impressive overall performance in terms of speed and precision,” says Tarbet. “Moreover, embedded functionality within its FANUC control, like the variable speed option, enable us to undertake boring operations without vibration, resulting in faster and more precise part processing.”

Wordsley General Engineering’s decision to invest in DN Solutions’ machine tools from Mills CNC is clearly paying dividends, resulting in the company having a full order book.Since their installation, both machines have been put through their paces.According to Tarbet, the new investments have helped the company “acquire over 10 new customers in just a few months”.

“We are delighted with our two new DN Solutions’ machines, and with the service and support we received from Mills CNC,” he concludes.
