Experimental investigation on friction under machining conditions with cutting fluid supply

Procedia CIRP, vol. 108, pp. 378–383

Abstract

In cutting processes, friction is mainly present on the rake and flank face of the tool. It has a direct influence on the thermo-mechanical loads applied in the cutting zone and thus on the surface integrity. To investigate the friction behavior experimentally, a friction test bench based on a lathe with cutting fluid supply was developed. Workpiece temperature was studied depending on machining conditions. The friction tests showed that the cutting fluid led to higher friction forces under the conditions investigated. Furthermore, the results revealed that an increase in the frictional force was accompanied by an increase in workpiece temperature.
