Abstract: Both a grinder system and a corresponding grinding method are based on a module, embodied preferably as a program or program segment, which, preferably automatically, defines the geometry of the corner cutting edge and the corner cutting face of a metal-cutting tool on the basis of predetermined peripheral conditions. The axial rake angle of the face-end cutting edge and the axial rake angle of the circumferential cutting edge as well as a desired effective profile can serve as the predetermined peripheral conditions. Further peripheral conditions may be a smooth transition of the cutting faces between the face-end chip cutting face, corner cutting face and circumferential cutting face. Tools are obtained that have a long service life and with which at the same time good machining quality can be achieved.

Abstract: A simulation system (20) for a CNC machine tool includes a swept surface calculation engine (21) for processing workpiece data and grinding wheel data representing information about the grinding wheel (12) and its programmed path to generate a set of geometric envelopes representing the solid volume occupied by the grinding wheel (12) as it moves along its programmed path. The envelopes, workpiece data and grinding wheel data are processed by a 3-D rendering engine (22) to produce a three-dimensional perspective image of the workpiece (11) as it would appear after being ground by the grinding wheel (12). The simulation system (20) also includes a manipulation and control interface 923) which may be used for a wide variety of purposes to enhance the three-dimensional image, such as position, orientation and zoom control, control of simulated illuminated light sources, control of texture maps and color maps and overlay grids which may be superimposed on the surface of the simulated workpiece image.
