Effect of the Contact Angle between the Cutting Edge and Surface of Cut on the Flank Wear Width in Turning Operations

Abstract

In metal cutting studies, the flank wear width (VB) is commonly used as a criterion or as a limit
 measure for the cutting tool life. From the point view of this work, there is a critique concerning the traditional
 limit measure (vB). The researchers in this domain do not take the diameter of the work-piece into
 consideration. In this situation, the contact angle, between the tool and the work-piece, should be determined
 from the limit measure of flank wear width. This work deals with the effect of the work-piece diameter on the
 limit measures and proposes a related limit measure for each diameter' For the experimental approach, certain
 confirmation tests were achieved. It seems that the work-piece diameter could modify the limit measure and it
 could be increased for large diameters, or decreased for small ones.
