16-14
The format for the G82 cycle is as follows:
G17(XY);
G82Z__K__X__I__Q__L__F__E__P__D__;
or
G82Z__K__Y__J__Q__L__F__E__P__D__;
G18(ZX);
G82Y__J__Z__K__Q__L__F__E__P__D__;
or
G82Y__J__X__I__Q__L__F__E__P__D__;
G19(YZ);
G82X__I__Y__J__Q__L__F__E__P__D__;
or
G82X__I__Z__K__Q__L__F__E__P__D__;
Table 16.B summarizes the G82 cycle parameters. For a detailed
description of these parameters, see the text below and page 16-8.

Programming both plane axes in the same G82 block results in the error
“TOO MANY AXES PROGRAMMED”
Figure 16.4 shows the axis motions that make up the G82 plunge grinding
cycle. This figure assumes that the YZ plane (G19) is active and that the Y
axis is programmed in the G82 block, making it the plunge axis.
