Type of machining for technology database access: Roughing
By setting the following optional parameters, you can define
additional contour elements:
A:Oblique cut at contour start
W:Oblique cut at contour end
R:Rounding
B1:Chamfer/Rounding at contour start
B2:Chamfer/Rounding at contour end
BP:Pause duration
BF:Feed duration
WS:Angle of the chamfer at the contour starting point (not yet
implemented)
WE:Angle of the chamfer at the contour end point (not yet
implemented)
Cycle run
1
Calculate the proportioning of cuts (infeed)
2
Approach the workpiece from starting point for first pass
3
Move at the programmed feed rate to the contour end point X2,
or if defined, to one of the optional contour elements
4
The contour is machined depending on the contour smoothing H:
5
Retract and approach for next pass
6
Repeat 3 to 5 until the contour starting point Z1 is reached
7
Return to starting point on paraxial path
8
Move to the tool change point according to the G14 setting
MT
M after T: M function that is executed after the tool call T
MFS
M at beginning: M function that is executed at the
beginning of the machining step
MFE
M at end: M function that is executed at the end of the
machining step
WP
Displays which workpiece spindle is used to process the
cycle (machine-dependent)
Main drive
Opposing spindle for rear-face machining
