Enhanced Level Commands
4.1 Program support functions (1)
Note
I fthe value 0 is set into
default.
If it is need to specify 0 mm or 0 inch, set a smaller value than the movable resolution.
Peck tapping cycle
Rapid traverse is performed to R level after positioning along the X and Y axes.
Cutting is performed from point R with depth Q (depth of cut for each cutting feed).
Subsequently a return is carried out to point R. Whether retraction is overridden or
not is specified by a value other than 100% set to GUD7 _ZSFI[2]. Moving the cut-
ting feedrate F is carried out from point R to a position distance d from the end
point of the last cutting. This is where the cutting is restarted.
The spindle is stopped once point Z is reached, and, subsequently, rotated in the
reverse direction for retraction.
Set d (distance to the point where the cutting is started) in GUD7 _ZSFR[1].
Note
I fthe value 0 is set into
default.
If it is need to specify 0 mm or 0 inch, set a smaller value than the movable resolution.
Axis switching
The canned cycle must be canceled before the drilling axis can be changed. An
alarm is issued whenever the drilling axis is changed in rigid mode.
S command
An alarm is issued whenever a speed higher than the maximum speed for the gear
in use is specified.
F command
An alarm is issued, if a value overshooting the upper limit of the cutting feedrate is
specified.
