Examination of the cutting force measured during the application of an octagonal insert, comparison with the cutting forces measured using other insert geometries in face milling

Abstract

Increasing productivity is a competitive advantage for manufacturing companies, so its research represents one of the defining directions in the field of machining. Efficiency can be affected by modifying technological parameters. One way to increase productivity is to increase the feed per tooth in face milling. This paper presents a cutting experiment with an octagonal insert and its results. At a constant depth of cut and a constant cutting speed, I investigated the effect of the feed on the cutting forces in face milling of non-alloy steel using five feeds per tooth. Using the results of the experiment and comparing them with the results of previous experiments, I analysed the changes in specific cutting force for four different insert geometries (insert shapes). From this, I concluded that the most advantageous from the point of view of energy consumption is the use of rectangular, then square, octagonal and circular inserts in the examined parameter range.
