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
