Tools wear at high temperature conditions by the workpiece in the
cutting tool, the friction of the chips, so that the tool material
gradually wear or breakage of the phenomenon appears. Research tool wear
causes prevent premature excessive tool wear and how to extend cemented
carbide tool life, which is affecting the efficiency of production,
processing costs and processing quality is an important topic.
Cemented carbide tool life T is defined as the total cutting
tool wear reaches a predetermined standard time (MIM), factors affecting
the tool life.
