In a process for determining when tolerances are exceeded during generation of NC parts programs, the defined CAD geometry is converted into an equivalent grid, preferably a triangular grid. A surface corresponding to the NC parts programs in form of a triangular grid is generated after conversion of the CAD geometry. The parts program takes into consideration the geometric attributes of the milling tool (diameter, shape, etc.). After two triangular grids have been generated from the starting data, i.e. the CAD geometry and the NC parts program, the distance between the two grids can be calculated and visualized.
