Abstract

By hobbing, distortion potential is induced into the workpiece, which leads to distortion of the gear teeth in the subsequent heat treatment process. To investigate the generation of distortion by hobbing precisely, the analysing methods have to be adapted to the process. To be able to choose adequate methods, preliminary investigations are accomplished to analyse the dimension and shape of the machining induced distortion. Since the hobbing process is divided into three regions with different process conditions, the influence of these differences on the distortion has to be considered. Therefore a variation of the facewidth is performed and the occurring forces are measured to analyse the process conditions. The results are used to derive suitable research and analysing methods.

## Abstract Soft tissue damage has been observed in hip joints with pathological geometries. Our primary goal was to study the relationship between morphological variations of the bony components of the hip and resultant stresses within the soft tissues of the joint during routine daily activities.
