5.4.7.8 Execute a roughing cycle

Rough cutting

Starting from the current axis position, the rough cutting sequence is as follows:

1. Diagonal approach to the start position calculated in the cycle in both axes.

The safety clearance and finishing allowance are taken into account.

2. Infeed in the infeed axis (transverse axis or longitudinal axis, depending on whether

"Face" or "Longitudinal" was selected).

The infeed is calculated within the cycle as follows:

– The input value "m1" is not exceeded.

– The infeed quantity is guaranteed to remain constant until the unmachined contour is

reached (taking finishing allowance into account).

3. Execution of the paraxial roughing motion in the cutting axis until the unmachined contour

is reached.

The finishing allowance is taken into account.

4. Withdrawal from the material in the infeed axis by the infeed distance.

5. Retraction by the clearance distance below 45

in both axes.

6. Return in the cutting axis to the start position calculated in the cycle.

7. New infeed in the infeed axis by the infeed depth calculated in the cycle.

All roughing cuts are performed one after another, as described above.

Finish cutting

When the final rough cut is completed, the contour is finish cut with the following motions:

1. Traverse in the infeed axis to the finished dimension for the contour, corrected by the

clearance distance.

2. Infeed in both axes (below 45

) to the contour start point.

3. Execution of the finishing motion along the parameterized contour.

4. Retraction by the clearance distance below 45

in both axes.

5. Return in the cutting axis to the start position calculated in the cycle.

6. Finally, the original position of the axes before the start of machining is approached

diagonally.
