Depth infeed rate – (only for perpendicular insertion and ∇)

FZ (only for G code) Depth infeed rate – (only for perpendicular insertion and ∇)

Maximum pitch of helix – (for helical insertion only)

Radius of helix – (for helical insertion only)

The radius cannot be any larger than the cutter radius; otherwise, material will remain.

Maximum insertion angle - (only for insertion with oscillation)

Chamfer width for chamfering (inc) - (for chamfering only)

Insertion depth of tool tip (abs or inc) - (for chamfering only)

* Unit of feedrate as programmed before the cycle call

Hidden parameters

The following parameters are hidden. They are pre-assigned fixed values or values that can

be adjusted using setting data.

PL (only for G code) Machining plane

SC (only for G

Safety clearance

Starting point

Starting point is automatically calculated - (only for ∇ and

Lift mode before new infeed - (only for ∇, ∇∇∇ base or ∇∇∇

Residual material contour pocket (CYCLE63)

When you have removed stock from a pocket (with/without islands) and there is residual

material, then this is automatically detected. You can use a suitable tool to remove this residual

material without having to machine the whole pocket again, i.e. avoiding unnecessary non-

productive motion. The finishing allowance should be set identically for all machining steps

because it does not count as residual material.

The residual material is calculated on the basis of the milling cutter used for stock removal.

It is also possible to run multiple residual material steps one after the other. In this case, the

milling tool should be selected to be smaller by a factor of no more than 3 for each new step.
