Study on highly efficient machining by small-diameter radius end mill -cutting efficiency of face cutting and side cutting in high speed milling

This study aimed to improve the efficiency of mold processing with high-speed milling and to collect basic data on high-speed milling In this work, we used a milling machine with maximum cutting speed of 160,000 min'1 and maximum feed speed of 15,000 mnVmin along with a small diameter end mill to examine tool wear and machining characteristics when the product of axial depth of cut and pick feed as well as the removal rate were constant. We further compared machining efficiencies for surface and side grinding The results showed that in high-speed milling, tool wear and surface roughness obtained in face cutting were lesser than that obtained in side cutting; thus, surface grinding was more effective.
