Multiple-Axis Machining | The PLANE function: Tilting the working plane (option 8)

Input parameters

Projection angle on 1st Coordinate plane?:

Projected angle of the tilted machining plane

in the 1st coordinate plane of the untilted

coordinate system (Z/X for tool axis Z). Input

range: from –89.9999° to +89.9999°. The 0° axis

is the principal axis of the active working plane (X

for tool axis Z, positive direction)

Proj. angle on 2nd Coordinate plane?:

Projected angle in the 2nd coordinate plane of

the untilted coordinate system (Y/Z for tool axis

Z). Input range: from –89.9999° to +89.9999°.

The 0° axis is the minor axis of the active

machining plane (Y for tool axis Z)

ROT angle of tilted plane?: Rotation of the

tilted coordinate system around the tilted tool

axis (corresponds to a rotation with Cycle 10

ROTATION). The rotation angle is used to simply

specify the direction of the principal axis of the

working plane (X for tool axis Z, Z for tool axis Y).

Input range: –360° to +360°
