Influence of the Cutting Speed and Feed Rate on Torque, Feed Force, Roughness and Shape of the Chips During Deep Hole Drilling

Abstract

This article describes methodology and realization of the deep hole drilling test. Goal of this trial is to define influence of the cutting speed and feed rate on torque and feed force. As well as during the test here was a focus on roughness and shape of the chips. A gun drill was used for deep hole drilling and we used etalon material, were here is possible to define cutting forces without any further testing of different steel grades. Also there is a description of CNC program, which was used for above mentioned testing and it can be utilized during other different trials.
