The PLANE Function: Tilting the Working Plane (Software Option 1) 12.2

TNC 640 | User's Manual for DIN/ISO Programming | 5/2013

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:

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

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°
