Programming a G82 causes the control to execute a face grinding cycle.

This cycle is typically used to grind the face of a part. Axis 2, the X axis

in our case, is the reciprocation axis and axis 1, the Z axis, is the plunge

axis. The G82.1 cycle is identical but begins with a pre-dress operation

prior to the grind.

For example, if t he G18 (ZX) plane is active and configured such that the

Z axis is axis one and the X axis is axis two, then the Z axis would be the

plunge axis and the X axis would be the reciprocating axis. The cycle

executes as follows:

1. The X axis moves to the primary reversal point (X) at feedrate E.

2. The plunge pick move (K) begins at feedrate F as the X axis

decelerates to the primary reversal point.

Important: It is the programmer’s responsibility to make sure that the

reciprocation moves extend beyond the part sufficiently such that the

plunge move can be completed before the wheel comes back in contact

with the part. Plunge moves begin as the reciprocation axis decelerates.

Therefore, feedrate, acceleration and deceleration should be considered for

all axes involved.

3. The X axis moves to the secondary reversal point (I).

4. The plunge pick move (Q) begins as the X axis decelerates to the

secondary reversal point.
