Detailed description
2.1 Path feedrate F
Basic logic functions: Feeds (V1)
28 Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Retraction acceleration, jerk
Acceleration is performed at maximum possible values.
This can be configured in machine data:
MD32300 MAX_AX_ACCEL.
Example
N55 M3 S500 G90 G18
; Set active machining plane
...
N65 MSG ("thread cutting")
MM_THREAD:
N67 $AC_LIFTFAST=0
; Reset before beginning of
thread
N68 G0 Z5
N69 X10
N70 G33 Z30 K5 LFON DILF=10 LFWP ALF=7
; Enable fast retraction for
thread cutting
; Retraction path = 10 mm
; Retraction plane Z/X
(due to G18)
; Retraction direction -X
(with ALF=3; retraction
direction +X)
N71 G33 Z55 X15
N72 G1
; Deactivate thread cutting
; If thread cutting
N69 IF $AC_LIFTFAST GOTOB MM_THREAD
;
was aborted
N90 MSG ("")
...
N70 M30
N55 M3 S500 G90 G0 X0 Z0
...
N87 MSG ("tapping")
N88 LFOF
; Deactivate fast retraction
before tapping
N89 CYCLE...
; Thread drilling cycle with
G33
N90 MSG ("")
...
N99 M3012.97
Control system response
At POWER ON and RESET, the retraction path is set as configured (MD), as is the state of
LFON or LFOF and LFTXT or LFWP using machine data:
MD20150 GCODE_RESET_VALUES
from the corresponding G group.
