An Analytical Predictive Model and Experimental Validation for Machining with Grooved Tools Incorporating the Effects of Strains, Strain-rates, and Temperatures

By effectively integrating a recently developed universal slip-line model with Oxleyʹs predictive machining theory, a new analytical predictive model for machining with restricted contact grooved tools has been developed and presented in this paper. A computational flow chart is provided to illustrate the method of integration. The cutting forces are predicted for varying flow stress properties to include the effects of strains, strain-rates, and temperatures. Extensive cutting tests involving the use of three groups of chip-grooves have been conducted to validate the new method. An encouraging good agreement has been found between predicted and experimental results.
