A free evaluation licence from Alphacam meant that a manufacturer could put a machine awaiting commissioning to work producing essential PPE for front-line health workers. Codem Composites had recently invested in a pre-owned Blackman & White CNC cutting machine, with a bed capacity of 2.2 sq m, to cut carbon fibre pre-impregnated with an epoxy resin. The carbon fibre serves to make components for the motorsport industry and satellite dishes.

“The machine hadn’t been fully commissioned and we had post-processing issues with the software and interface – we didn’t want to invest several thousand pounds in software immediately, given the uncertainty surrounding COVID-19,” explains managing director Kevin Doherty. “However, when we got the call asking us to cut NHS scrubs, we approached Alphacam to help get the machine up and running. Alphacam supported our efforts by providing us with a free evaluation licence.”

The software gave Codem complete flexibility and speed of production by optimising nests. Running at a capacity of around 500 full sets of scrubs a week, the Blackman & White machine cuts components for a group of volunteers in Northamptonshire to put together.

Alphacam accurately interrogates the DXF file for each of the patterns, and computes all permutations and variables.

“So rather than someone having to work everything out manually, such as what we are going to cut, how we are going to cut it, and what’s got to go where, we simply input which components we need in which sizes,” he says. “Alphacam does the rest, including helping us with the correct cutting speeds and feed rates. The first cut parts came off the machine within 24 hours of installing the software.”

The range of machine tools from the Chiron Group has become even smarter with the new ProtectLine and CutLine software solutions. Available in the UK & Ireland from the Engineering Technology Group (ETG), the modules form part of the SmartLine portfolio, making it possible to increase productivity, improve part quality and boost machine availability and capacity.

ProtectLine allows companies to prevent potentially significant, expensive damage and production downtime. The system is characterised by a digital twin that runs ahead of the physical machine in ‘real time’ during operational mode. For instance, if the digital twin encounters problems or even a crash, the software shuts the machine down in a controlled manner that preventively protects it from collisions.

According to ETG, one of the main features that sets this software solution apart from other established systems is that the simulated model always corresponds to the current production situation. Machine crashes can be reliably prevented, even in the case of small adjustments or operating errors. A further advantage is that ProtectLine integrates directly into the new TouchLine control panel.

ProtectLine fully replicates the physical machine, including the complete machine tool, cutting tools and tool holders, as well as the workpiece. Just like a ‘real’ machine, the software enables virtual tool changes and simulates a virtual machining process in parallel to the actual machining process.

Through this simulation, the geometry of the virtual workpiece always corresponds to that of the actual workpiece, resulting in a realistic model. Used together, the ProcessLine and ProtectLine modules of the SmartLine portfolio form an integrated digital process chain.
