Defining the working plane via a single incremental
spatial angle: PLANE SPATIAL

Application

Use an incremental spatial angle when an already active tilted

working plane is to be tilted by

another rotation

. Example:

machining a 45° chamfer on a tilted plane.

Before programming, note the following

The defined angle is always in effect in respect to the

active working plane, regardless of the function you

have used to activate it.
You can program any number of

PLANE RELATIVE

functions in a row.
If you want to return to the working plane that was
active before the

PLANE RELATIVE function, define

the

PLANE RELATIVE function again with the same

angle but with the opposite algebraic sign.
If you use the

PLANE RELATIVE function in a non-

tilted working plane, then you simply rotate the non-

tilted plane about the spatial angle defined in the

PLANE function.
Parameter description for the positioning behavior:

Input parameters

Incremental angle?: Spatial angle about which the

active machining plane is to be rotated additionally

(see figure at right). Use a soft key to select the

axis to be rotated about. Input range: –359.9999° to
