Specifying the positioning behavior of the PLANE

Independently of which PLANE function you use to define the tilted

machining plane, the following functions are always available for

the positioning behavior:

Automatic positioning

Selection of alternate tilting possibilities (not with PLANE AXIAL)

Selection of the type of transformation (not with PLANE AXIAL)

Danger of collision!

Cycle 28 MIRROR IMAGE may have different effects in

conjunction with the Tilt working plane function. The effect

mainly depends on the programming sequence, the mirrored

axes and the tilting function used. There is a danger of collision

during the tilting operation and subsequent machining.

Check the sequence and positions using a graphic simulation

Carefully test the NC program or program section in the

Program run, single block operating mode

1 Cycle 28 MIRROR IMAGE programmed before the tilting

function without rotary axes:

The tilt of the PLANE function used (except PLANE AXIAL)

The mirroring is effective after the tilt with PLANE AXIAL or

2 Cycle 28 MIRROR IMAGE programmed before the tilting

function with a rotary axis:

The mirrored rotary axis has no effect on the tilt specified

in the PLANE function used, because only the movement

of the rotary axis is mirrored
