Roughing Cycles - Siemens SINUMERIK 808D User Manual

● Press the above softkey and the following screen appears:
The rest of the thread cutting process is exactly the same as that described for the manual thread cutting function.
The only difference is that thread cutting is not started with the marker pulse from the spindle encoder but with the angle that
was calculated in the previous screen for thread repair (thread recutting) as the start angle offset.

Roughing cycles

Functionality
The roughing cycles (integrated in the control) are the easiest way of producing common paraxial cutting contours. They are
defined by setting particular input parameters in the appropriate screen forms.
The contour can be machined using the following position of the contour:
● Outside right
● Inside right
● Outside left
Roughing is either longitudinal or planar.
