Abstract

PURPOSE:To avoid the operation delaying a finish processing start point to the start point of rough processing, by providing a function automatically correcting a command value given to a read section for the inside of a numerical controller. CONSTITUTION:A rough processing start point which is one of commands inputted to a read section 1 and a finish processing start point are stored in a storage section 3 once and enter a logical operation section 2 via a comparison section 9. When the comparison is made at the section 9 and the finish processing start point is smaller than the rough processing start point, a correction 10 is made so that a point greater by a 1/2 screw pitch from the rough processing start point is taken as the finish processing start point and output is given to the section 2 again. If the finish processing start point is greater than the rough processing start point, the command is outputted to the operation section 2 as its is. Next, both start points inputted to the operation section 2 are used, a movement command is operated so that two tools can be moved simultaneously and output is made to a driving section 4. Thus, the driving section 4 moves a machine tool 5 and makes a work with a prescribed screw pitch.
