PURPOSE:To obtain easily the cross section of a work at any height, by driving X, Y tables by making compensation with the upper guide displacement multiplied by a suitable factor at the time of picture pattern checking. CONSTITUTION:Switch 20 is open during normal processing. By command NC tape 17 and an angle instruction, control device 16 outputs amounts of displacement X and U respectively to X-shaft drive motor 5 and U-shaft drive motor 1, and by moving the table and the upper guide, processing is operated. At the time of checking picture patterns, the power supply for processing is not actuated and no processing is operated, but command NC tape 17 is read in the same way as during processing and control device 16 outputs instruction values X and U in the same way as during processing respectively to X-shaft and U-shaft. At taper-cut picture pattern checking, switch 20 is closed, and the product of upper guide displacement U and the set value of variable resistor 19 is added to X as the amount of compensation. |
