Computer-aided design system based on spline interpolation of micromills for high-speed processing of products manufactured by laser ablation and grinding

Microcutters are one of the important elements of the technological system for high-speed machining. A new approach to the automated design of micromills using spline interpolation is proposed. Existing methods do not allow to form a continuous contour of the front helical surface for processing in one pass. In this regard, the trajectory of the laser head was calculated and analytical approximation of the profile with given geometric parameters of the cutter was derived that allows applying laser ablation technology for the manufacture of helical surfaces of micromills.
