Investigation of cutting force in face milling with an octagonal insert

Abstract

Increasing the efficiency of machining is a major goal of industrial companies. One way to increase efficiency is to increase the cutting speed. This paper presents a cutting experiment with an octagonal insert and its results. Using a constant depth of cut and a constant feed per tooth, I investigated the effect of cutting speed on cutting forces during face milling of non-alloy steel using five spindle speeds. The change in cutting force and specific cutting force showed that increasing the cutting speed increases the material removal rate with a decrease in energy demand in the studied parameter range.
