Defining The Working Plane With Spatial Angles: Plane Spatial - HEIDENHAIN TNC 620 User Manual

Defining the working plane with spatial angles:
PLANE SPATIAL
Application
Spatial angles define a working plane through up to three rotations
in the non-tilted workpiece coordinate system (tilting sequence A-B-
C).
Most users assume three successive rotations in reverse order
(tilting sequence C-B-A).
The result is identical for both perspectives, as the following
comparison shows.
