Determination of a Mathematical Model of Taper Wear for a Longitudinal Surfacing Operation

Abstract

Turning is one of the most widely used machining processes in the mechanical engineering industry. Thus, the choice of optimal cutting parameters (cutting speed, feed and depth of cut) is very important in order to ensure a better surface condition of the machined parts and the life of the cutting tools, which requires great relationship with the wear of the tool-part interface. The result of a good choice of cutting conditions can be seen by a reduction in this wear. During machining, the geometric shape and the physical state of the tool are modified by the combined action of the cutting forces and by the temperature reached by the cutting edge. These modifications which gradually increase with the duration of machining are commonly grouped under the term wear of the tool. They appear on the active part of the tool. In this work, we propose an optimization method allowing determining a mathematical model of the wear and tear by applying the experiment plan. This model highlights the relationship between the elements of the cutting regime (cutting speed, feed and depth of passes) and the responses studied (Wear in clearance).
