Abstract

Cutting is a process of extensive stresses and plastic deformations. The high compressive and frictional contact stresses on the tool face result in a substantial cutting force R. Cutting forces are the factors for the evaluation of the cutting power in machining and influence the deformation of the workpiece, accuracy, chip formation and machinery system stability. This paper built an experiment system to investigate the influence of cutting parameters including feed f, depth of cut t, feed rate v to a tangential cutting force Pz on structural steel materials C45. The final results confirmed tolerance between theory and experiments 5% - 9%.
