抜粋

Dry cutting technology without cutting oil is required in order to decrease environmental burden and to reduce processing cost. In this research, for the purpose of establishing dry drilling process with indexable insert drill, we investigated basic characteristics of dry drilling and experimented several methods to suppress tool wear. As the results, in drilling conditions where the initial feed rate change to low near the exit of the hole during the drilling processes, the highest temperature of the inserts goes down, and a minimum point of the highest temperature of the inserts was shown at the optimal change position of feed rate In these minimum points, the rake face wear became minimum, and was influenced to the highest temperature of the inserts, it is thought that the change position of feed rate at the minimum points are determined by the drilling depth.
