Liechti Engineering AG

Using NC Optimization Software to Enable New Product Introduction

Liechti Engineering AG is a market leader for programming and machining solutions for the manufacturing of flow profiles on turbine components. To deliver quality products that achieve maximum economic benefits, the machine tool provider staffs a demonstration facility where customers are introduced to technologies and machining strategies that can further improve their machining processes. Liechti engineers used Third Wave Systems® software product, Production Module™, to conduct an internal evaluation of the software to determine whether or not the software would benefit their customers.

“We are sure that Production Module is the right toolpath analysis and optimization product for our machines and our customers’ applications.” – Andreas Finger, Liechti Engineering AG
