A Study of Deep-Hole Machining of Stainless Steel with Small-Diameter Drill

Article Preview

Abstract:

This paper describes an influence of the cutting condition on the tool performance and the hole shape accuracy in a deep-hole machining of stainless steel with small-diameter drill. The drilling tests were carried out by changing the feed, tool diameter and drill length in order to investigate the appropriate cutting conditions for drilling the holes with deep depth. The results indicate that the increase of the thrust force leads to the buckling of the drill and the work hardening of the workpiece causes the tool failure.
