Introduction This manual describes the specifications of MITSUBISHI CNC 700/70 Series. [. . . ] u/2 e · 2, 4, 6, 8, 10, 11 and 12 are executed at the rapid traverse feed rate. i d B k k k k x 184 12. Program Support Functions 12. 1 Machining Method Support Functions (6) Longitudinal cutting-off cycle (G75) When the slotting end point coordinates, cut depth, cutting tool shift amount, and cutting tool relief amount at the cut bottom are commanded, automatic slotting is performed in the longitudinal direction of a given bar by G75 fixed cycle. The machining program is commanded as follows.

Program Support Functions 12. 1 Machining Method Support Functions (7) Compound type thread cutting cycle (G76) When the thread cutting start and end points are commanded, cut at any desired angle can be made by automatic cutting so that the cut section area (cutting torque) per time becomes constant in the G76 fixed cycle. Various longitudinal threads can be cut by considering the thread cutting end point coordinate and taper height constituent command value.
