Abstract

tn metal cutting studies, the flank wear width (VB) is commonly used as a criterion or as a limit
meas,re for the cutting tool life. From the poini ,iew of this work, there is i 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'rvork 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, cefiain
confirmation tests were achieved. It seems tf,ut itr. work-piece diameter could modiff the limit measure and it
could be increased for large diameters, or decreased for small ones'
