A STUDY ON TYPES OF WEARS IN MILLING TOOLS
Keywords:
: Tool wear, Tool life, crater wear, flank wearAbstract
The main aim of this work is to study the different types of wears caused during the milling processes and the
causes. Tool wear can be described as the gradual failure of tools while the cutting operation is being performed regularly.
This paper shows that there are different types of tool wears that occur in different conditions. The main occurrence of wear
was seen due to mechanical friction, adhesion, high cutting temperature. Also the chemical wear was promoted due to
cutting forces. By the study of wears caused wear patterns like rake face wear, flank wear, fracture, breakage and chipping
were also observed. The research results are of great help in selecting the materials for the tools and the wear control in tool
where high speed machining is required.
