Note that for other kinds of workpiece attributes (rectangular pockets, slots, and so on), you can choose any point relative to the attribute as the temporary program zero point. First, the subprogram is written using the center of a hole as the program zero point for all positioning movements. At the end, remember to shift the program zero point back to its original position with the command G52 X0 Y0. Note that the values specified in the G52 command are always specified from the original program zero point (not from one shifted position to another). Though this application does not require it, you can also shift the Z axis program zero point.

The command G52 X8.0 Y2.0 will shift the program zero point to the lower right hole.

Here's how it works:įor the workpiece shown in Figure 1, the command G52 X2.0 Y2.0 will shift the program zero point to the center of the lower left hole (a great point of reference for programmed coordinates in the absolute mode). Newer Fanuc and Fanuc-compatible controls have a command word to specify a temporary shift of the program zero point: the G52. Instead, they will program each hole individually in the absolute mode.įixture offsets don't provide much help, since it can be cumbersome to set up a special program zero assignment for each hole, and you have a limited number of fixture offsets with which to work (many controls have six). Since the incremental mode can make programming much more difficult, many programmers do not take advantage of sub-programming for this kind of application. However, traditional thinking has been to develop the positioning movements in the subprogram in the incremental mode, since if positions are commanded in the absolute mode, the same hole would be machined four times. The commands needed to mill one of the holes can be stored in a subprogram and executed four times from within the main program. This is a good application for sub-programming. Consider the four identical circular counter-bored holes that must be milled in the workpiece shown in Figure 1. It is common to machine several identical workpiece attributes from within a single program.
