Following the introduction of the Vortex high-efficiency area clearance strategy in Powermill 2014, Delcam’s new roughing strategy has now been added to the FeatureCAM, Partmaker and Delcam for Solidworks CAM systems.

According to the company, Vortex gives the fastest safe metal removal from solid-carbide tooling, particularly designs that give deeper cuts by using the full flute length as the cutting surface.

It can be used for two- and three-axis roughing, three-plus-two-axis area clearance and rest machining. Vortex produces toolpaths with a controlled engagement angle and so maintains the optimum cutting conditions for the toolpath that would normally be possible only for the straight-line moves.

Vortex also uses a minimum-radius parameter, calculated to make sure that the machine tool can keep up the cutting feed rate in corners and, more generally, for any non-straight part of the toolpath.

In addition, the control of the engagement angle that is possible with the Vortex strategy also makes the performance of the tool more predictable because it is operating closer to the optimum cutting conditions associated with a straight-line cut.

Key features and benefits

  • As a result of the toolpaths’ controlled engagement angle, higher feed rates are possible, so the cutting time will be shorter while cutting will be undertaken at a more consistent volume-removal rate and at a constant feed rate, so protecting the machine.
  • The minimum-radius parameter makes the cutting process more predictable as the machine should run at the programmed feed rate throughout and not slow down.
  • Control of the engagement angle means that it is easier to adjust the feeds and speeds being used to machine a particular part such that a tool can be relied on to cut before it needs to be changed. A tool change can then be added into the program where appropriate.
  • A series of trials run by Delcam on different machine tools within its Advanced Manufacturing Facility has shown that a time saving of at least 40 per cent is quite achievable, with the biggest percentage savings being found when cutting a sample part in tool steel. The cycle time for the part was reduced from 121 minutes to 34 minutes, a reduction of 71 per cent.
  • In an example where 2,000 stainless steel components were being produced monthly, the number of tools being used was reduced from 300 to 100 each month. The replacement tools were more expensive but the overall costs were still reduced by around 50 per cent.

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.
