摘要：
This work presents an experimental study on the cutting process for polyamides PA 6 and PA 66-GF30 (reinforced with 30% glass fiber). The experiments were carried out on extruded workpieces using cemented carbide (K15) tools in turning. The objective of this study is to evaluate the influence of the glass fiber reinforcement on the chip compression ratio R-c, chip deformation (a)over-circle, friction angle p, shear angle Phi, normal stress sigma, and shear stress T under prefixed cutting parameters (cutting velocity and feed rate). The experimental physical model was compared with the Merchant equation.
