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 arc
 B1:Chamfer/Rounding at contour start
 B2:Chamfer/Rounding at contour end
 BP:Break 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 calculates 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
WP Displays which workpiece spindle is used to process the
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
