The Comparative Analysis of Two Methods for Peripheral Milling Cutting Force Measurement of Oak Wood

Abstract

Two measuring methods (direct and indirect) for peripheral milling cutting force, with the aim of machinability examination of the oak wood, are presented in this paper. Extensively research was performed with over 450 measurements of cutting forces and cutting power. Measurements were conducted for different cutting depths, feed rates and cutting tool geometry. Very strong linear dependence between the peripheral cutting forces calculated upon model values of cutting power (F-om*) and peripheral milling force model values (F-om), was established by the means of comparative analysis. Latter is proved by high value of determination coefficient, which amounted to 0,92. Furthermore, it has been proven that there is the same trend for both measuring methods of peripheral forces, taking into consideration that direct method results show average 23% higher values than those gained using indirect method.
