Polishing is an important finishing process in injection mold manufacturing. The purpose of polishing is to remove minor scratches and decrease the surface roughness of the workpiece. It is well known that in-mold fabrication 37–50% of the total time is spent on ﬁnishing operations, which are mostly performed by skilled workers employing traditional techniques. And the processing of automation and optimization of manufacturing processes are becoming increasingly important tasks due to the increasing demand for higher precision and productivity in manufacturing processes in the modern industry.
Therefore, high efficient polishing machining and ﬁnishing technology are strongly desired for a long time, which will also increase productivity and decrease the labor intensity.
