Delcam’s Powermill CAM system has been used in a project for the Airbus A400M military transporter at aerospace supplier Tritech.

The company was asked to machine from solid the fuel connectors that are located in the wings of the aircraft; a total of 64 variants for each wing.

With its Delcam software and a Huron MX4 twin-pallet, five-axis machining centre, Tritech was able to move from casting to direct machining of the connectors and achieve significant weight reductions for Airbus.

If the components were machined from solid blocks of aerospace aluminium and the wall thicknesses controlled to a tolerance of 0.015mm, then the integrity of each connector could be maintained with the required 1mm wall thickness.

Engineers at French machine-tool manufacturer Huron worked with Delcam to complete the programming and machining of the trial components.

Essential to the success of the project were Powermill strategies developed for machining engine ports.

These included ‘auto-tilt’ functionality, which gives efficient material removal while maintaining minimal clearance between the cutting tool and the part surface with no risk of rubbing or gouging.

It allowed the surface-finish requirements to be met for the through bore on the fuel connector components.

Tritech ordered the Huron machine, plus Delcam’s Powermill software, and began the move to full-scale production.

With their training complete, Tritech now has the in-house capability to develop up to six complex parts in one week.

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.
