EXPERIMENTAL RESEARCH ON WEAR IN THE CUTTING PROCESS

Abstract

Cutting tools are subject to several types of wear. The rate at which the wear
process occurs has a decisive role on the machining costs. Many of the parameters
that determine production costs, such as machining time, part failure rate and tool
replacement interval, are affected by how well the cutting tool is working. Damage
to the cutting tool due its wear occurs to the cutting edge surfaces of the tool that
come into contact with the workpiece and with the chips. With the experimental data
from this study, groups of values such as feed, depth, speed and durability
corresponding to a certain practical permissible of wear cutting tool value were
determined, in order to be able to optimize in practice the values of the cutting
regime parameters so as to ensure a imposed durability and wear of cutting tool.
