Delcam is working with Iruba and Hermle to develop a five-axis machining method for the creation of ‘fir-tree’ profiles in components for turbo machinery.

The method is based on the trochoidal machining strategies in the Powermill CAM system.

The milling approach allows complex ‘fir-tree’ profiles to be produced on milling machines such as the Hermle C60 five-axis machining centre. This eliminates the need to bring in specialist broaching equipment.

Key benefits of product application

  • The use of Powermill’s trochoidal strategies offers benefits including high material removal rates with lower and more consistent cutting forces.
  • More consistent cutting forces ensure higher accuracy in the position and shape of the slots with minimal thermal effects on the profile surfaces.
  • The process reduces the number of specialist cutting tools required and cuts the machining time in steel alloys by 30–40 per cent compared with alternative standard milling solutions.

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.
