As dominating manufacturing process to create external gears, hobbing is of major industrial importance. Hence, a continuous process optimisation to satisfy the demand of the market is necessary. Changing the substrate material is a basic approach in optimization of operation times. Due to acquisition costs and lacking knowledge most companies hesitate to use cemented carbide hobs which endure higher cutting speeds compared to HSS/PM-HSS. Offering experience based knowledge which can be used to revise the cemented carbide application in industry, cutting parameters were varied investigating their influence on the wear behaviour. The impact of high performance cutting parameters within a fly cutting analogy test was examined using different measurement techniques and simulation results.
