Programming a G82 or G82.1 causes the control to execute a plunge
grinding cycle using only two axes. You can use this cycle to grind a slot
into a part or to grind a part that is narrower than the grinding wheel or
grinding path. The G82.1 begins with a pre-dress operation prior to the
grind.
The plunge axis for this cycle is whichever axis of the active plane that is
programmed in the G82 block. Only one of the axes in the active plane
should be programmed or an error results. The reciprocation axis for this
cycle is the axis that is not in the active plane.
For example, assume that the G19 (YZ) plane is active and you have
configured the Y axis as axis one and the Z axis as axis two for that plane.
The cycle executes as follows:
For example, if the G19 (YZ) plane is active and configured such that the
Y axis is axis one and the Z axis is axis two, then you could program either
Y or Z in the G82 block, but not both. The X axis would be the
reciprocating axis. Assuming the Y axis is to be used for the plunge
depth, the cycle executes as follows:
1. The X axis moves to the primary reversal point (X) at feedrate E.
2. The plunge pick move (J) begins at feedrate F as the X axis
decelerates to the primary reversal point.
