Comment
; explain reversal points 1 and 2
; Reversal point 1: without exact stop
; Reversal point 2: Exact stop fine
; Feed for oscillating axis, feedrate, infeed axis
; Switch off oscillation motion at reversal point 1
; After delete DTG spark-out and approach end position
; After DTG, approach relevant reversal position
;
; 3 sparking-out strokes
; End position = 0
; enable oscillation for the Z axis
the current position of the oscillating axis in the
Machine Coordinate System
reversal position 1
set the marker with index 1 to value 0
(Reset marker 1)
the current position of the oscillating axis in the
Machine Coordinate System
the beginning of reversal range 2
(here: reversal point 2 -6),
set the axial override of the infeed axis to 0%.
set the marker with index 2 to value 0
(Reset marker 2)
the current position of the oscillating axis in the
Machine Coordinate System
reversal position 1,
set the axial override of the oscillation axis to 0%
Set the axial override of the infeed axis to
100% (so that the previous synchronized action
is cancelled!)
the distance-to-go of the partial infeed is
0,
