A three dimensional linear processing machine and a method of compising and controlling machining program

摘要

The chuck (10), for positioning and holding a pipe at any rotational angle position around the axial center, is provided with the three dimensional linear processing machine. When the machining program (PRO) is composed, a plurality of the shape patterns (KPT) classified machining modes concerning pipes by machining shape is displayed on the display (23). Furthermore, dimensional data item concerning selected shape pattern is displayed on the display (23). Then, the machining program (PRO) is composed on the basis of the input code parameter (CP) and the selected shape pattern (KPT). Besides, shift quantity (TMz) and (TMy) are measured when the pipe to be machined is installed on the chuck (10), and on the basis of this, the machining program (PRO) is amended and executed.
