Delcam will preview a new rib-machining module for its PowerMILL CAM system on stand H57 in Hall 8 at the Euromold exhibition, which will be held in Frankfurt, Germany, from 25–28 November. The new module, which will be available as part of the PowerMILL 2015 R2 release scheduled for January 2015, will speed up and simplify the machining into tooling of cavities to form ribs.

Reinforcing ribs are required in many types of plastic mouldings, from electrical housings to containers to furniture. They are typically much deeper than they are wide, which poses special challenges when machining the cavities needed to form them. In many cases, these challenges prompt companies to use EDM to form the features rather than machining.

According to Delcam, the new PowerMILL module makes it much easier and safer to program the machining of cavities for narrow ribs, even when the cutter’s length is much greater than its diameter. Using a dedicated rib-machining strategy gives a better surface finish than using a standard finish machining option and also improves efficiency by limiting the number of air moves.

The first stage of the process is to create a pattern for a single rib, by sketching a line along its length. PowerMILL uses this line to identify automatically all the surfaces needed to form the rib. The machining sequence is then calculated. Usually, the machining will either be undertaken by cutting progressively deeper along the centreline of the cavity using a form tool matching the rib profile or by profiling along either side of the rib with a standard tool.

In many cases, most, if not all, of the ribs in a part will have similar depth and width profiles. Thus, once the user is happy with the sequence developed for the first rib, the same machining strategies with the same tooling can be applied across the complete network of ribs so minimising programming times.

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.
