Measurement of cutting temperature of drill point and cutting characteristics during low frequency vibratory drilling of aluminum

Abstract

Cobalt high speed steel drills brazed with sheathed thermocouples were utilized in the measuring cutting temperature of the drill face, and the relationship between the cutting temperature and the cutting characteristics (cutting force, drill wear) was investigated. The temperature at the drill face during low frequency vibratory drilling was lower than that in the conventional drilling. Low frequency vibratory drilling also showed more effectiveness in the drilling of aluminum than the conventional drilling.
