Beschreibung

An increasing demand for complex shaped parts requires new methods for increasing the productivity in machining of those parts. The utilization of a 5-axis kinematic in a grinding machine offers high potential for reducing process times as well as improving surface quality. Face grinding is known for producing high quality surfaces but is limited to flat or convex surfaces. The goal of this work is to gain an understanding of the effect of process angles on the surface quality in face grinding. Path planning for free form grinding can be improved by the fitting of the surface curvature of the workpiece to the shape of engagement due to these angles. This paper shows the effect of the yaw angle on the surface roughness for different process parameters. Productivity can be improved by applying higher feed rates while still reducing the surface roughness by selecting optimized yaw angles.
