摘要：

The analytical models, developed in Part I of this paper, for estimating the temperature distributions along the cutting edge and on the clearance face of a twist drill are evaluated using an experimental technique that measures average drill flank temperatures. While the transient model tends to overestimate the values of the average flank temperatures, especially during drilling to a one diameter hole depth, the temperatures predicted from the steady state model agree reasonably well with the experimental results. The difference between the analytical and experimental results varied with the physical and thermal properties of the powder metallurgy work materials used in this experiment. The analytical drill temperature distribution models are also compared with others found in the literature. © 1990.
