Positioning of C-axis at the rapid
feedrate
Positioning of C-axis at the rapid
feedrate
Q
2
Positioning of Z-axis at the point
"Q
1
- K" at the rapid feedrate
Positioning of X-axis at the point
"Q
1
- I" at the rapid feedrate
Q
3
Cutting along Z-axis from point Q
2
to
the commanded point Z
Cutting along X-axis from point Q
2
to
the commanded point X
Q
4
Z-axis returns to the Q
3
cycle start
point at the rapid feedrate. The cycle
is repeated until Z-axis reaches the
programmed Z level.
