Often the program comes in a circular pattern. Which often seems to be repetitive. Let's learn how to copy it instead of doing it.
When a program is rotated in a circular fixed degree, the G72.1 is used. You see how the subprogram is linked to the Maine program. In the same way, it is also linked to the subprogram and to copy it in a fixed degree.
The programming format is
G72.1...P...L...X...Y...R...
L is a no. of program in rotation(compulsory)
R is degree between two program(compulsory)
Note : The program gets easy if your starting point of program is same with end point of program after completion of rotation copy.
G16,G17, G18, G19, G28, G51, G51.1 must not be specified in this program.
