Zegla-Plast Kunststoffspritzerei and Co from Schwarzenbach in Germany is using Delcam’s Powermill CAM software to help manufacture complex plastic parts for the automotive and processing industries.

Delcam’s Powermill CAM software makes a significant contribution to the precision of the tools and, therefore, of the plastic products.

Its open interfaces have enabled a novel CAM programming solution for electrode machining – the ‘macrogenerator’.

Hans Hacker, EDP operator and the ‘intellectual father’ of the macrogenerator, said: ‘At Zegla-Plast, we often design complex tools for which 300 to 400 electrodes may be required.

‘To write the NC program for machining an electrode in Powermill, I would normally have to select the strategy for every single cutter, enter the speeds and feed rates, select the cutting tools, start the calculation and then repeat the entire process.

‘This takes a lot of time, is fiddly and a lot of work.

‘So it was essential to find a way of automating the CAM programming of the electrodes.

‘The result was a much easier and quicker system.

‘First, you allocate article numbers to the electrodes in the data-entry dialogue of an Access database, then you can enter various predefined parameters – such as offset, precision and material.

‘Then I launch the macrogenerator with Powermill running in parallel to it.

‘In the background of the program, there is a small-tools database that holds all the necessary milling information.

‘The macrogenerator reads in every electrode from the database and automatically checks the smallest radius of the workpiece geometry to be processed.

‘Following this, the macrogenerator directly selects the most efficient machining strategy.

‘If everything is okay, the electrode goes off to be milled and the macrogenerator checks or modifies the parameters for the next electrode,’ he added.

Ferdinand Hoischen, sales director of Delcam, said: ‘The reason why the macrogenerator can function at all lies in the open structure of our CAM system.

‘Powermill offers the advanced user the possibility to create their own interface, through which they can have an influence on the calculation process, carry out editing and then see the effects of the changes,’ he concluded.

Delcam supplies software and services that help manufacturing companies to maximise their profitability by increasing productivity, improving quality and reducing lead times. The company is the world's largest specialist supplier of computer-aided machining software, with its PowerMILL, FeatureCAM, Partmaker and ArtCAM programs making up the most comprehensive range of CAM systems from any developer.

This broad selection allows Delcam to offer a CAM system capable of machining virtually any product, in any material on any type of equipment. Delcam also develops product design, tooling design and quality control programs. The unique Tribrid Modelling approach to design incorporates solid modelling, surface modelling and triangle modelling in a single program, enabling complete design and reverse engineering projects to be undertaken without transferring data between software.

Delcam's Powerinspect offers fast, reliable comparison of parts, prototypes and tooling against CAD data on all types of inspection equipment and even on machine tools. This versatility has made it the world's leading hardware-independent inspection software. Related programs are available for checking machine tool set-up and part location. Delcam software is used in over 80 countries worldwide by around 40,000 organisations, from large multi-nationals to small sub-contractors, in industries including aerospace, automotive, dental, engineering, footwear, medical and toolmaking.
