Study on Tools with Restricted Tool-Chip Contact Length (Part 2)

Variation of Coefficient of Friction on Rake Face with Reduction of Tool-Chip Contact Length

Abstract

In the previous paper, the slip line construction of the plastic field produced by restricted contact tools was discussed.
Based upon the characteristics of the slip line field, a quantitative treatment for variation of coefficient of friction on rake face with an artificial restriction of tool-chip contact length is proposed in this paper, in comparison with experimental results. The experimental results appear to support the treatment.
