Computerized simulation of thread form grinding process

This paper proposes a simplified two-dimensional numerical simulation method for form grinding the thread on cylindrical workpieces without solving the simultaneous system equations that produce numerically unstable solutions in the presence of undercutting, interference, or double enveloping. Here, construction of the ground thread’s tooth profile involves subtracting the grinding wheel locus projected onto the workpiece’s transverse plane. Since the entire process occurs in the transverse plane, it is faster than 3D CAD-based calculations and is not only numerically stable but allows calculation of the instantaneous contact lines between the grinding wheel and ground thread.
