The chip processing system of large scale machine tool, such as planomiller, turning machine, boring machine and CNC machine, has been continuously used in many industrial fields. As the performance of chip processing system is improved, cutting work with high-precision is also required. This study aims to study the characteristics of the edged part of cutter depending on removing the cutter support in cutter assembly. As the results, the damaged spot in edged part of cutter was different whether the cutter support was installed or not. By removing the cutter support, the safety factor of edged part of cutter was decreased about 4.7 times and furthermore there were some advantages in less than 1.7kN of cutting force.
