Vortex flyer - .PDF file.

Delcam will demonstrate the huge time savings that can be made with its Vortex high-efficiency area-clearance strategy at Seco’s ‘Inspiration through Innovation’ manufacturing best-practice event to be held at the company’s premises in Alcester, Warwickshire, on 24–25 September.

According to the company, the Vortex strategy offers substantial time savings by allowing users to make deeper cuts using the full flute length as the cutting surface.

In addition, two enhancements in the Powermill 2015 release will give even greater reductions in machining time with Vortex compared with conventional roughing. The first change allows toolpaths to approach the part from outside the stock at the cutting height, both for open pockets and in areas where earlier cuts have made this possible.

The second change allows an increased feed rate to be set for non-cutting moves. The default value is set at double the rate for the cutting moves but this can be altered as required for each machine tool. 

The extra time that can be saved depends on the shape of the part, but the company says an additional saving of around 20 per cent should be expected above the earlier releases of Vortex.

Key features and benefits

  • A series of trials run by Delcam on different machine tools within its Advanced Manufacturing Facility has shown that time savings of up to 70 per cent are possible with the Vortex strategy.
  • Vortex produces toolpaths with a controlled engagement angle for the complete operation. This maintains the optimum cutting conditions for the entire toolpath that would normally be possible only for the straight-line moves. 
  • The cutting time is significantly shorter, while cutting will be undertaken at a more consistent volume-removal rate and feed rate, so protecting the machine.
  • Shock loading caused by changes in the contact angle is minimised, preventing chipping of the flutes.  
  • The stability of the cutting conditions gives more consistent edge temperatures, so prolonging the life of the tool coating and removing heat damage to the surface of the part. 
  • The ability to use stepdowns of three, or even more, times the tool diameter spreads the tool wear evenly over the cutting surface of the tool, again contributing to longer tool life.

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.
