Defining The Working Plane With The Projection Angle: Plane Projected - HEIDENHAIN TNC 620 User Manual

The PLANE Function: Tilting the Working Plane (Software Option 1) 11.2
Defining the working plane with the projection angle:
PLANE PROJECTED
Application
Projection angles define a machining plane through the entry of
two angles that you determine by projecting the first coordinate
plane (Z/X plane with tool axis Z) and the second coordinate plane
(Y/Z with tool axis Z) onto the machining plane to be defined.
Before programming, note the following
You can only use projection angles if the angle
definitions are given with respect to a rectangular
cuboid. Otherwise there will be deformations on the
workpiece.
Parameter description for the positioning behavior:
See "Specifying the positioning behavior of the
PLANE function", page 371.
Input parameters
Proj. angle 1st coordinate plane?: Projected
angle of the tilted machining plane in the 1st
coordinate plane of the fixed machine coordinate
system (Z/X for tool axis Z, see figure at top right).
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. See figure at top right for
positive direction)
Proj. angle 2nd coordinate plane?: Projected
angle in the 2nd coordinate plane of the fixed
machine coordinate system (Y/Z for tool axis
Z, see figure at top right). 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 the 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;
see figure at bottom right). Input range: –360° to
+360°
