At the Turning Days exhibition in Germany, Delcam will demonstrate the latest developments for the programming of turning and turn-mill equipment in its FeatureCAM feature-based CAM software. Enhancements include options that increase productivity, improve surface finish and reduce tool wear.

Smoother lead-in and lead-out moves reduce any witness marks when finishing larger turned parts in a number of sections. The ability to specify the optimum retract angle for turn-grooving operations allows a better surface finish on the part.

Improvements have also been made to the definition of the initial stock and part alignment, the method for calculating index limits, the options for multi-spindle, multi-turret machines and more.

Turning Days is set to take place on 17–20 April 2013 in Villingen-Schwenningen.

Key enhancements

Definition of initial stock and part alignment

  • Function is now more similar to the setup process for milling
  • Support has been added for semi-finish canned cycles
  • Curves of revolution are recognised from STL models

Milling improvements

  • New method allows B-axis rotary milling to be carried out on features that would otherwise require excessively long cutters
  • Alternative method for calculating index limits calculates limits based on the size of a solid revolve of the part
  • Method gives an index distance closer to the part shape and so produces more efficient toolpaths

Options for multi-spindle, multi-turret machines

  • Part transfers have been integrated into the FeatureCAM output
  • Simulation and post-processing of these operations is supported
  • Handling of synchronisation points has been enhanced to simplify the optimisation of the machining sequence between the various elements of the machine

Probing sequences

  • These can now be incorporated into CAM programs, making it easier to undertake unsupervised production operations by allowing automated checks to be carried out before, during and after machining
  • Before machining, sequences can be created to check that the expected part and fixture have been loaded in the correct orientation
  • Probing routines can be introduced at any stage during manufacturing

Method for generating html setup sheets

  • Information can be extracted from the FeatureCAM project to provide a detailed list of the tooling to be used, with an illustration of each tool, together with the dimensions of the initial stock and an image of the finished part

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.
