Kind Code:
A
Abstract:
PURPOSE:To complete processing in a short time with a simple program, by providing a means which discriminates if a tool is at the upper or lower part of a prescribed boundary and giving the information on the boundary on which the tool can travel. CONSTITUTION:A program to specify a desired final curved plane 102 is given to a memory. In addition, the information of boundaries 103 and 104 designating the upper and lower limit of the region to be processed is also inputted, where the region to be processed is refrerred to as the amount of movement of a shaping tool determined by one shaping amount. The shaping starts from a start point ST to an upper limit 103 by moving the tool. The tool makes processing to a lower limit 104 along the final curved plane 102, proceeds shaping along the boundary 194 and goes to the upper limit 103 along the plane 102. Next, the lower limit 104 is taken as the new upper limit 103', and a lower limit 104' is set and the next shaping is made.
