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.

Reversible parameter 0 : Select this only for finished shapes without hollow areas (pockets). With the beginning of the pockets, the tool is pulled up in the 45-degree direction with each cycle until the finished shape is finally traced. 1: This can be selected regardless of whether the finished shape has hollow (pocket) parts or not. A method that traces the finished shape with each cycle is used for the beginning of the pockets. Depending on the parameter setting, pocket machining ON/OFF is automatically determined by the number of axes in the finish shape start block. (If omitted, the program being executed is designated. ) If the A command is omitted, the program being executed are applied. [. . . ] LAS TORRES, MONTERREY, N.
