Method for establishing data defining tool path for rough machining

摘要

In a method for generating data defining the machining depth along a tool path, grid points are generated according to split points indicating a form of a model, and rough machining data for contour milling is generated according to the grid points, so that rough machining data which presents overcutting can be prepared. Contour points are generated and drilling points are set according to a comparison with cut planes so that the drilling points can be set easily and automatically. The contour points are retrieved successively so as to easily generate a tool path for contour milling.
