Case Study Simulation, optical metrology reduce number of tool iterations

The Bernecker Group, a Germany-based manufacturer of sheetmetal as well as insert moulded plastic components, has combined a CAD/CAM solution with a simulation system and optical metrology to ensure the best tools for complex parts. By Joachim Tschauner.

Higher engine power requirements in the automotive industry go hand in hand with ever more stringent exhaust gas limit values. In order to meet the tight standards, turbochargers are increasingly combined with a downstream exhaust gas recirculation (EGR) system to reduce the engine’s untreated NOx emissions – a solution implemented in the new VW Golf GTD, for instance. “This technology is becoming increasingly popular because emission limit values cannot be met without it,” reports Thilo Maisenbacher, head of design at Bernecker.
