Figure 16.2 illustrates the reciprocation, plunge, and crossover motions of
a typical surface grinding cycle (G83 Incremental Plane grinding in this
case) .

Modality and Programming
These surface grinding cycles are modal. Once programmed, the cycle is
executed in each subsequent block that contains the appropriate parameters
and parameter values. The G codes corresponding to these cycles do not
have to be programmed in each block.
Typically crossover and plunge axis motions are coordinated with the
motion of a reciprocating axis.
You can access Grinder Prompts through the Quick-view screens
(described in chapter 5) to simplify programming.
