Case Study CAD/CAM systems fulfil quality and reliability

| Editor: Susanne Hertenberger

Germany - As a manufacturer of components for aircraft engines, Aerotech Peissenberg (ATP) needs to fulfil the highest requirements regarding quality, reliability and price/performance ratio. Qualified employees and modern technology are essential for making this possible. The aviation company has managed to reduce processing times for various components by around 30%.

Reducing processing times for various components by around 30% has been made possible by innovative roughing strategies provided by the hyper-Mill Maxx Machining performance package from Open Mind, among other things, the company says. The aviation industry sets very high standards for its suppliers. This is true for companies that supply rotationally symmetrical and prismatic components that are used in modern engines. The conditions and requirements for such companies are therefore very strict. All employees at ATP – founded about 20 years ago within the MTU Group – are aware of the high demands placed on them.

The company’s core competencies include complex mechanical machining, surface finishing and checking of diverse safety-critical components made of alloys that are difficult to machine and have diameters of up to 1250 mm. Almost all modern multi-stage engines use these components, says Tolga Bayraktar, head of technology at ATP. He notes: “I always feel safe when I am sitting in an airplane as a passenger, since the safety-related components in almost all passenger aircrafts in the world are built by us.”

But the experts at ATP are not only sought after for their extensive expertise regarding production. Their knowledge is also crucial for new components while they are still in the development stage, as Bayraktar explains: “Of course, our customers come up with design ideas for the engine components. However, our employees’ expertise is vital when the time comes to select a design that is suitable for production.” What matters in the end is not simply the functionality of the blisks, impellers, spools, rings, housing and so on. Also equally important is manufacturing the components in a timely manner at reasonable costs - known too as the Design-to-Cost process. ATP designers have the know-how on optimal production technologies and processes to make this process achievable.
