A mathematical model and a numerical algorithm for profiling a disk tool are considered. The optimization of the tool profile is investigated depending on three parameters of its installation relative to the part: the crossing angle, the shortest center distance and the adjusting axial displacement. The optimization criterion is the smallest profile height with the minimum curvature. The developed algorithm is implemented as MATLAB program. Numerical experiments shown that the tool profile, due to optimization, can change the depth by 2-5 times and the curvature by 2-3 times. Keywords helical surface, disk tool, mathematical model, profiling, numerical algorithm, optimization.
