Visualization of workpieces in the simulation of milling processes

摘要

A process for the simulation of the shape of a workpiece by means of simulation of a milling operation, wherein a workpiece blank by means of a family in a three-dimensional space (x, y, z) is modelled and all the straight line parallel to an axis (z), with a workpiece by means of cutting edges of the family with a virtual milling edge (fk) according to a predetermined pathway (fb) in the three-dimensional space on the basis of the resultant points of intersection (h₁, H₂; H_in, H_out) the straight line of all the swept volume is determined by the amount of points of intersection of a grid is formed, which describes the workpiece contour and which is supplied to a display device, in order to the surface quality of the workpiece to be produced for the purpose of optimization of the parameterization of the milling machine for carrying out to be analyzed, wherein for the simulation of a milling operation with a ball headed milling cutters a in the machining over-painted volume of the family of partial volume in the form of two balls or hemispheres, which is simulated by means of a further partial volume of a horizontal cylinder, in the milling direction are connected to one another, the balls or hemispheres, as well as the connecting cylinder, in each case, the milling cutter radius and points of intersection (h₁, H₂; H_in, H_out) with the family determined separately for each of these partial volume are.
