Summary: | PCT No. PCT/US83/01160 Sec. 371 Date Jul. 28, 1983 Sec. 102(e) Date Jul. 28, 1983 PCT Filed Jul. 28, 1983 PCT Pub. No. WO85/00067 PCT Pub. Date Feb. 14, 1985.A computing unit (12) produces control signals which, when applied to the control inputs of a conventional numerically controlled lathe (10), cause the lathe cutting tool (60) to be positioned such that contours varying in three dimensions may be realized in a spindle (18) mounted, rotating workpiece (20). The control signals include x and z position signals, defining the position of the cutting tool with respect to the radial (24) and axial (22) axes, respectively, of the workpiece (20), and i and k lead control signals which define the distance traveled by the cutting tool, per revolution of the workpiece, in the radial (24) and axial (22) workpiece axes, respectively. A filtering process (134, 136, 140) operates to delete each control signal having i and k values which are within the x and z tolerance values, respectively, of the immediately preceding control signal, to thereby reduce both the volume of stored data and machining time. |
