EXPERIMENTAL INVESTIGATION ON THE EFFECT OF CUTTING PARAMETERS ON CUTTING TEMPERATURE DURING TURNING OF X200Cr12 WITH COATED AND UNCOATED INSERTS

Abstract

One of the most important phenomena associated with machining operations is the cutting temperature because it affects the life of the cutting tool. Cutting parameters and insert material are the important conditions that affect temperature in turning. In this study, tests were carried out on X 200 Cr 12 steel during turning process. In ordre to measure the cutting temperature of the tool, the thermocouple method was used. The results illustrate that cutting temperature increases with depth of cut, feed rate, and the rotational speed. Due to the high conductivity of the insert coating, the tool cutting temperature reaches much higher levels than in the case of uncoated inserts. The conductivity of the insert affects the cutting temperature. The most influential parameters on the cutting temperature are feed rate and depth of cut.
