<p>PURPOSE:To prevent a tool and work to be cut from interference by inputting the coordinate data of an original position easily through ten-key, approximating a graph drawn on a CRT precisely, and at the storage of working data in a cassette magnetic tape, storing the original position coordinate data as unset data. CONSTITUTION:The original position coordinate data consisting of X-axis ans Z- axis data 7, 8 can be inputted through the ten key in accordance with a CRT screen 6 for setting the original positon. Therefore, the original position coordinate data to be displayed on the CRT screen 6 can be set up and a graphic pattern can be precisely approximated to the tool path of a real lathe. The original position is registered unset data 11, 12 at the storage of the working data in the cassette magnetic tape, so that an original position unset error can be generated at the time of automatic path calculation. Consequently, the original position coordinate data are set up in the NC lathe as safe data and the interference between the tool and a work to be cut or the like can be prevented.</p> |
