Groove (CYCLE930)

You can use the "Groove" cycle to machine symmetrical and asymmetrical grooves on any

straight contour elements.

You have the option of machining outer or inner grooves, longitudinally or transversely

(face). Use the "Groove width" and "Groove depth" parameters to determine the shape of the

groove. If a groove is wider than the active tool, it is machined in several cuts. The tool is

moved by a maximum of 80% of the tool width for each groove.

You can specify a finishing allowance for the groove base and the flanks; roughing is then

performed down to this point.

The dwell time between recessing and retraction is stored in a setting data element.

Finishing allowance in X – (not for finishing)

Finishing allowance in Z – (not for finishing)

Chamfer width (FS1...FS3) or rounding radius (R1...R3) - (not for

stock removal 1)

Parameter selection of intermediate point

The intermediate point can be determined through position specification or angle.

The following combinations are possible - (not for stock removal 1 and 2)

Intermediate point X ∅ (abs) or intermediate point X in relation to X0 (inc)

Intermediate point Z (abs or inc)

Angle of the 1st edge

Angle of the 2nd edge
