Experimental Study of the Effect of Changing the Shape of Tool Geometry on the Magnitude of Cutting Forces when Turning Tool Steels

Abstract:

Tools applied in various cutting processes are constantly exposed not only to thermal, mechanical but also chemical stresses, which has a significant impact on the wear of the cutting tool, but also on the cutting performance itself. By measuring the components of the cutting force, we can predict the wear or suitability of the cutting tool for machining given types of materials. The present study investigates the effect of changing the shape of the tool geometry on the magnitude of cutting forces in turning tool steels. The measurement of cutting forces was carried out on a conventional lathe with a Dynamometer attachment, interchangeable cutting inserts of DNMG and WNMG type were used as tools, tool steels produced by PM and conventional metallurgy were used as the machined material. The cutting tools were selected regarding their common use in engineering production, the tool steels were selected with regard to their application in industry in the production of rotary tools.
