Effect of uncut chip thickness on the ploughing force in orthogonal cutting

Abstract

Determination of the ploughing forces is necessary for monitoring the wear of the cutting tool in micro cutting. The aim of this research was to increase the accuracy of determining the ploughing force and the determination of the influence of the uncut chip thickness on the ploughing force. A new method for determining the ploughing forces is suggested in this article. It was found that the ploughing forces determined by the new method were greater than those determined by the method comparing total forces at different flank levels of wear. It was first established that the uncut chip thickness influences the ploughing force.
