Abstract

PURPOSE:To enhance operational efficiency and manufacture the device at low cost by converting the tracing locus obtained from tracing with a stylus into numerical information, by driving and controlling the processing device for a work on the basis of the information, and thereby eliminating necessity for use of any external medium for storage. CONSTITUTION:At all times in operation, the contact pressure of a stylus 9 with the surface of a model 1 is sensed, and the amount of change epsilonx-epsilonz of the contact pressure according to progress of the time is entered in a numerical control device NC. This NC device controls motors 8, 13 for driving a table 2 and the stylus 9, respectively, so that the amount of change epsilonx-epsilonz of the contact pressure becomes zero. At this time the position of table 2 with respect to a scale 3 is sensed by a position sensor 4, and the position information obtained X1-Z1 is converted into numerical information. On the basis of this numerical information, the drive signals X2-Z2 for a table drive motor 2 and a cutter drive motor 25 are prepared to serve for processing of the work 27 through tracing of the surface of the model 1.
