Programming a G84 causes the control to execute a multi-pass face

grinding cycle. This cycle is typically used to grind the face of a part in a

situation where a shifting of the grinding wheel position is necessary to

cover several different surfaces to be ground on the face. Axis 2, the X

axis in our case, is the dither axis and axis 1, t he Z axis, is the plunge axis.

The G84.1 cycle is identical but begins with a pre-dress operation prior to

the grind.

The G84 cycle differs from the G82 cycle in several ways. First, the X

axis dither differs from reciprocation in that it is made up motions that are

centered about the X axis coordinate and are made only during the plunge

move. Second, the plunge motion is a continuous move to the plunge

depth (Z) instead of a series of plunge pick moves as used with the G82

cycle.

The third and most significant difference between the G84 and the G82

cycles is that the G84 incorporates an X axis shift, made after the

completion of each plunge. The length of this plunge shift (distance

between plunges) is defined by the Q parameter.
