FUNDAMENTAL-STUDIES OF DRIVEN AND SELF-PROPELLED ROTARY TOOL CUTTING PROCESSES .2. EXPERIMENTAL INVESTIGATION

An extensive experimental investigation has been carried out to verify the developed mechanics of cutting analyses for the fundamental drive n and self-propelled rotary tool cutting processes. This involved test ing the dynamic or perfect equivalence between the rotary tool and equ ivalent classical processes over a wide range of inclination angles, c ut thickness and rake angles using statistical processing techniques. The collinearity conditions at the shear plane and rake face have also been tested as part of the model verification. It has been shown that all the force components, deformation and basic cutting parameter tre nds and quantities required for perfect equivalence have been satisfie d as were the necessary collinearity conditions. The verified models p rovide a deeper understanding of the cutting mechanics and characteris tics of these ingenious material removal operations and form the basis for the development of predictive cutting models for the fundamental and complex practical rotary tool operations.
