Roughing the relief cut elements:
● Approach of the starting point for the next relief cut axis by axis with G0 When doing so,
an additional cycle-internal safety clearance is observed.
● Infeed along the contour + finishing allowance with G1/G2/G3 and FF2.
● Approach of paraxial roughing intersection point with G1 and at feedrate FF1.
● Rounding along the contour, retraction and return are carried out as with the first
machining step.
● If there are further relief cut elements, this sequence is repeated for each relief cut.

Finishing:
● The cycle starting point is approached axis by axis with G0.
● The contour starting point is approached with G0 in both axes at the same time.
● Finishing along the contour with G1/G2/G3 and FF3
● Retraction to the starting point with both axes and G0
