    摘要: A safe and efficient machining process design is realized by extracting the unmachined shape and by three-dimensionally visualizing the unmachined shape without generating a machining track. The present device 1 comprises a displacement unit 2 for displacing a machining tool on the surface of a three-dimensional product shape model at arbitrary positions without causing interference between the product shape model and the machining tool, a detection unit 3 for detecting a distance between the arbitrary position and the machining tool, and a preparation unit 4 for preparing the three-dimensional unmachined shape by using the minimum value of the distance obtained for each point on the surface of the shape model when the arbitrary point is moved.

    摘要: A method of eliminating surface gouging in computer-aided control of cutter paths, comprising the steps of: (a) generating three-dimensional computer images of a surface to be emulated and of a revolving cutter head; (b) imposing an x-y coordinate grid work onto each image and assigning a z coordinate to the cutter depth and surface height for each grid; (c) while digitally moving the cutter head over the emulated surface, determining the highest sum of z coordinates for each grid within the superimposed area; and (d) using such highest sum as the lowest z coordinate for a cutter reference point at each such digital position of the cutter, the highest sum being adjusted for any difference between the reference point and cutter depth at such highest sum grid.
