Defining The Working Plane Via A Single Incremental Spatial Angle: Plane Relativ - HEIDENHAIN TNC 640 User Manual

Multiple-Axis Machining | The PLANE function: Tilting the working plane (option 8)
Defining the working plane via a single incremental
spatial angle: PLANE RELATIV
Application
Use a relative spatial angle when an already active tilted working
plane is to be tilted by another
chamfer on a tilted plane.
Programming notes:
The defined angle is always in effect in respect to
the active working plane, regardless of the tilting
function you used before.
You can program any number of PLANE RELATIV
functions in a row..
If you want to return the working plane to the
orientation that was active before the PLANE
RELATIV function, define the same PLANE RELATIV
function again but enter the value with the opposite
algebraic sign.
If you use PLANE RELATIV without previous tilting,
PLANE RELATIV will be effective directly in the
workpiece coordinate system. In this case, you can
tilt the original working plane by entering a defined
spatial angle in the PLANE RELATIV function.
You can select the desired positioning behavior.

Input parameters
Incremental angle?: Spatial angle by which the
active machining plane is to be rotated. Use a
soft key to select the axis to be rotated around.
