Delcam Professional Services is set to promote its expanded range of services for aerospace manufacturers and maintenance, repair and overhaul (MRO) companies in the UK pavilion at the Singapore Air Show on 11–16 February. These services are designed to help both manufacturing and repair companies whenever they need to increase productivity, reduce lead times or improve quality and consistency.

According to Delcam, increased demand for its process development and prototype manufacturing services has led to the addition of a Mori Seiki NMV 5000 machine to the range of five-axis machining equipment within its Advanced Manufacturing Facility. The new machine extends the company’s ability to undertake the high-speed, high-precision five-axis machining of complex parts.

The range of support from Delcam Professional Services is mainly intended to help any company whose own engineering resource, whether people or equipment, is needed to maintain its existing operations.

The services provided can vary from supplying extra design, programming and machining resources when the customer’s own staff or equipment are overloaded through to developing software to automate existing manufacturing methods or to establishing new turnkey processes for the production of novel designs.

Recent developments at Delcam

‘Fir-tree’ profile machining method

  • A new five-axis machining method, programmed with Delcam’s Powermill CAM system, enables the creation of ‘fir-tree’ profiles in components for turbo machinery.
  • This method was developed in partnership with Iruba, a German provider of engineered solutions, and machine-tool manufacturer Hermle. 
  • It allows these complex shapes to be produced on milling machines, such as the Hermle C60 five-axis machining centre, rather than having to use specialist broaching equipment.
  • The use of Powermill’s trochoidal strategies to program the operation gives a number of benefits, in particular high material removal rates with lower, and more consistent, cutting forces.

Hybrid machine programming

  • The programming, using Delcam’s adaptive machining technology, of a new hybrid machine from Hamuel Maschinenbau enables the remanufacturing of high-value metal components such as turbine blades.
  • The Hamuel hybrid machine combines five technologies in one unit: five-axis CNC milling, laser cladding, robot polishing, inspection and laser marking. Any of these processes can be combined, as required by the particular project.
  • The equipment costs less than a multi-machine repair cell, as well as saving on floor space.
  • Using a hybrid machine, it is possible to remove the damaged area of a turbine blade by milling off the worn material and then build the material back up using the cladding technology.
  • A second machining operation, using high-speed five-axis milling, then produces the final shape, with a smooth transition between the original part and the new material.
  • Polishing and laser marking can be undertaken to complete the component, if required.
  • In-cycle part inspection, using Delcam’s adaptive machining software, provides feedback to orientate the parts, assess defects and ensure accuracy throughout the various stages.

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.
