<p>PURPOSE:To enable drilling according to a pattern cycle which does not meet the regulations of the standard drilling pattern cycle with respect to a numerical control unit for the drilling operation by machine tools. CONSTITUTION:Besides that data of the standard drilling pattern cycles are obtained after being calculated in the arithmetic section 16, the standard patterns are also inputted directly in the input section 12 and stored (14C). When executing, these standard drilling patterns are displayed on a setting display 24 (e.g., a CRT unit) and data for a pattern are established. Thereby perforations can easily be added or deleted through an image-plane input method (e.g., a light pen) readily enabling the preparation of an irregular drilling pattern cycle.</p> |
