<p>PCT No. PCT/JP84/00045 Sec. 371 Date Oct. 17, 1984 Sec. 102(e) Date Oct. 17, 1984 PCT Filed Feb. 14, 1984 PCT Pub. No. WO84/03244 PCT Pub. Date Aug. 30, 1984.A three-dimensional tool path determination method for determining at least one path out of an approach path along which a tool 11 of a machine tool having three or more controlled axes is made to approach a workpiece, and a retraction path along which the tool 11 is retracted from the workpiece after machining is completed. The three-dimensional tool path determination method includes steps of designating a prescribed tool path pattern from among a plurality of tool path patterns, which prescribed tool path pattern includes an undecided portion (coordinate values of P1, P2), entering data specifying the undecided portion of the tool path pattern, which data includes at least a target position (Pe) and a distance (d1), calculating the undecided portion by using the input data and an arithmetic expression that corresponds to the designated tool path pattern, and creating NC data specifying a three-dimensional tool path by using the obtained coordinate values of the points (P1, P2).</p> |
