MILLING CANNED CYCLES.<br />
CNC 8065<br />
(REF: 1209)<br />
·54·<br />
G88. Circular pocket canned cycle<br />
Canned cycles (·M· model)<br />
C Milling pass or width.<br />
If not programmed or programmed with a 0 value, it assumes a value of 3/4 of the diameter<br />
of the selected tool.<br />
If it is the same as parameter "J" (pocket radius), it only runs the finishing pass.<br />
If programmed with a value greater than the tool diameter, the CNC issues the relevant error<br />
message.<br />
L Finishing pass.<br />
If not programmed or programmed with a 0 value, it does not run the finishing pass.<br />
H Feedrate for the finishing pass. If not programmed or programmed with a 0 value, it is carried<br />
out at the roughing feedrate.<br />
V Tool penetrating feedrate. If not programmed or programmed with a 0 value, it is carried out<br />
at 50% of the feedrate in the plane.<br />
Basic operation:<br />
1 If the spindle was previously running, it maintains the turning direction. If it is stopped,<br />
it starts clockwise (M03).<br />
2 Rapid movement (G0) of the longitudinal axis from the starting plane (Zi) to the reference<br />
plane (Z).<br />
3 Rapid movement (G0) of the longitudinal axis up to 1 mm off the part surface.<br />
The movement permits, as in the case of the figure, a fast approach to the machining<br />
surface when the safety coordinate (Z) is far away from the surface.
