Surface Grinding Fixed Cycles
Chapter 16
16-16
Important: It is the programmer’s responsibility to make sure that
the reci procation 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.
5. The reciprocation and plunge pick moves continue until the plunge
depth (Y) is reached.
6. After the plunge depth (Y) is reached, reciprocation continues and
the programmed number of spark-out passes are executed.
The format for the G83 cycle is as follows:
G83X__I__Y__J__Z__K__R__Q__L__F__E__P__D__;
Table 16.C summarizes the G83 cycle parameters. For a detailed
description of these parameters, see the text below and page 16-8.
