Mastercam Multiaxis is an add-on for Mastercam Mill 3D, Router 3D, Mill-Turn and Mastercam for SolidWorks. It improves productivity with simultaneous four- and five-axis machining capability for Mastercam. Notably, Mastercam Multiaxis offers a wide range of multi-axis machining strategies, both basic and advanced. These tool paths are also useful for the advanced control of three-axis machines.

The new Multiaxis Unified tool path allows users to select multiple pieces of input geometry to generate the tool-path pattern. Using those geometry choices, Multiaxis Unified picks the best algorithm to calculate the path. This single tool path gives users access to all the surface-based tool paths, as well as the geodesic tool-path options, in a single interface.

New Deburr tool-path enhancements include a new option ‘number of cuts along edges’ that allows users to add multiple cuts to the deburr tool path, rounding or flattening edges, to create a quality edge on deburred parts. Additionally, new ‘tilt range’ options allow users to limit tilt when machining type is set to five-axis (simultaneous) or 3+2 axis.

Maintaining climb and conventional machining is critical for surface finish and tool life. ‘Controlling climb and conventional cutting’ now provides control of climb or conventional cutting when working with surfaces that may require using both sides of a tool. It was previously impossible to maintain this while machining a curved shape that would require the use of both sides of the cutter.

Swarf milling tool-path enhancements include the ‘drop tool to floor’ option, which controls whether Mastercam will drop the tool path down to a floor or retract to the bottom of swarf surfaces.

Umati was on display at the EMO Milano 2021 exhibition last October, connecting up more than 50 machines from all over the world, almost half of them remotely. The presentation was part of an international programme staged by the VDW to promote the ‘world language of production’.

“After making our first appearance over two years ago in Hanover, we were delighted to be back in a face-to-face setting – and with such an impressive demonstration,” said Dr Heinz-Jürgen Prokop (pictured), chairman of the VDW. In his status report, he emphasised: “The most important milestone in the development of the OPC-UA Interface for Machine Tools was the publication of the specification just over one year ago. It is now available free of charge worldwide, meaning that all companies that manufacture, use or offer software for machine tools can now develop and refine their products based on this specification.”

The Machine Tool Group is contributing to the development of this harmonised specification. Above all, it ensures the standardisation of a certain set of data relevant to the entire mechanical and plant engineering sector. The first step concerns the identification of the machine. In terms of digital nameplates, the type of machine is basically irrelevant. All machines have a manufacturer, serial number, date of manufacture, date of acquisition, location and so on.

Thanks to OPC UA for Machinery, technology-specific specifications now no longer have to worry about identification but can concentrate fully on rendering the relevant technology-specific data. The next step in development involves harmonising the operating states of machines, as these too could be used at a higher, more universal level.

Umati currently has almost 200 partners.

Intelligent software algorithms are essential for real-time collision avoidance, but they are only half the story. The other half is a well-designed user interface that enables operators to drive the software effectively. In their latest co-operation ModuleWorks, a technology provider for digital manufacturing solutions, and Chiron Group, a CNC machine tool manufacturer, put operator experience at the centre of a new GUI for the ModuleWorks Collision Avoidance System (CAS).

The ModuleWorks CAS uses real-time machining data and look-ahead technology to detect imminent collisions and stop the machining process before an actual collision occurs. Chiron Group uses CAS as part of its ProtectLine digital system, to protect the company’s high-end machining centres from potentially expensive damage and downtime.

In addition to sophisticated algorithms, effective collision avoidance requires careful set-up by the operator to ensure the system accurately represents the entire machining process, including the fixtures, workpiece and tools. The user interface therefore plays a pivotal role in the acceptance and effectiveness of the system.

“We asked ourselves: what do operators need from a GUI in order to use the CAS effectively,’” says Jasper Sanders, product manager at ModuleWorks. “The obvious answer was to ask the operators, so we created a project team with the Chiron Group and their machining team. This proved a great approach. In less than 12 months we were able to launch a new GUI that raises usability and operator acceptance.”

Pascal Schröder, development co-ordination – digitalization at Chiron Group, adds: “Collision avoidance is indispensable for safe and cost-effective manufacturing. Through our co-operation we have a system that truly supports machine operators and encourages them to use the full benefits of collision avoidance technology on our machining centres.”

Hexagon’s Esprit CAM software now offers a build preparation workflow within the CAM environment to provide a single, streamlined platform for both additive build and finishing operations. Its patented Part-to-Build workflow was developed to change the prevailing 3D-printing paradigm from the preparation of rapid prototypes to industrialisation with a true CAM experience that includes build-preparation steps and programming tools for post-processing printed parts with wire EDM and milling machine tools.

In series production, a given part will be produced hundreds of times with the same build plates, orientation, support structure generation and exposure strategy assignment. The Part-to-Build workflow addresses component preparation and job preparation with dedicated functionality from one piece of software, making manufacturing smarter by enabling volume efficiencies and automating repetitive tasks, such as slicing.

Designed for CAM programmers, Esprit CAM’s build preparation employs a workflow based on parametric data that ensures high accuracy and adherence to the geometry of the original CAD model until it is sliced in preparation for 3D printing. The software reads and manipulates all popular parametric CAD formats and automatically identifies those surfaces that require support. In addition, the software assists with the creation of support structures, generating parametric surfaces with teeth, fragmentation and perforation.

It is possible to automate support generation for future builds by assigning a pre-set to a region on the surface, capturing valuable production know-how and improving future productivity. As the majority of models for 3D-printed parts are STL-based, Esprit CAM also provides an STL (mesh) slicer that leverages a built-in software kernel.

The UK’s largest maker of leisure vehicles is using the full design capabilities of PTC to help it bring its latest model to an expectant market that is now booming. Swift Group, which employs over 1000 people at its 100-acre headquarters near Hull, has now launched Basecamp 6, a compact crossover camping vehicle.

Engineers at the family-run business have been using PTC’s Creo design software to introduce several new features, making the most of simulation tools, piping and cabling, and advanced assembly to deliver its product.

“Our models undergo significant transition and Creo has enabled us to reduce rework in our factory, check design in more detail and take a thorough approach to ergonomics,” explains Paul Cunningham, engineering director at Swift Group. “Another big step forward has been the way that people from inside and outside the business can engage with 3D models created in PTC software. Internal users that rely on them include senior decision-makers, members of the sales team and employees from the factory floor responsible for building products. External users are typically dealers, who can interrogate Creo Illustrate to identify exactly the part they need to fulfil a customer’s specific requirements and then click through to an ordering system. What it all means is that we have been able to deliver our most ambitious camper vehicle yet in the Basecamp 6…on time, to budget and with all the stylish features and benefits.”

Just like the touring caravans it manufactures, Swift Group has come a long way in the 57 years since it was founded by Ken Smith, who built and sold his first caravan for £289.

Today, the company generates nearly £270m in annual sales.
