The model proposed hare calculates the residual stresses, in surface plunge grinding. As a whole, the mathematical model consists of three main parts, which correspond to three separated computer programs: GRIND, TEMP and STRESS.
The program GRIND converts the grinding parameters (forces, speeds, wheel and workpiecs properties) to heat transfer data. With the results of the previous program, the second program TEMP calculates the temperature history. A third program STRESS calculates the stress all over the workpiece, induced, during the grinding process.
This model predicts residual stresses in the workpiece and includes the residual stresses due to phase transformation in the material due to surface plunge grinding operations.
