Cutting Forces During Strain Hardening of Austenitic Steel by the Method of Deformational Cutting

One of the promising areas of applying the method of deforming cutting is for obtaining wear-resistant friction surfaces due to the effect of strain hardening. The emerging cutting forces, especially when the treated surface is modified at a deep level, can lead to a loss of efficiency of the tool used. In this regard, obtaining formulas for predicting the cutting force components in deformational cutting has become an important task. This work investigates the change in the cutting force component depending on the operating parameters such as the cutting depth, feed and cutting speed. The measurements of the cutting force components were made when processing austenitic steel due to its tendency to strain hardening. The cutting forces were measured using a modern piezoelectric dynamometer. By approximating the experimental data, empirical formulas were obtained for calculating the cutting forces components within selected ranges of variable parameters. The formula to determine the main component of the cutting force proved to be the most accurate.
