Surface Grinding Fixed Cycles
Chapter 16

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.
Table 16.B
G82 Cycle Parameters
Parameter: Definition: Default Value: Possible Value:
Non-plane axis 2 reciprocation primary reversal point from last cycle programmed abs. or inc.
Reciprocation axis integrand 3 reciprocation secondary reversal point from last cycle programmed abs. or inc.
Either plane axis 2 plunge depth from last cycle programmed abs. or inc.
Plunge axis integrand 2 plunge pick at primary reversal point from last cycle programmed inc. only
Q 3 plunge pick at secondary reversal point plunge pick at primary reversal inc. only
L 3 number of spark-out passes zero zero to 999
F 2 plunge pick feedrate last feedrate programmed valid F word
E 3 reciprocation feedrate from last cycle or last F valid F word
P 3 for G82 2 for G82.1 dress program number from last cycle programmed valid program number
D 3 number of auto-dress executions zero zero to 999
1 must be programmed 2 must have been programmed in some previous block if omitted 3 optional
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.
