15.10 Tilting the working plane (software
option 1)
Application, function
The functions for tilting the working plane are
interfaced to the TNC and the machine tool by the
machine tool builder. With some swivel heads and
tilting tables, the machine tool builder determines
whether the entered angles are interpreted as
coordinates of the rotary axes or as angular
components of a tilted plane. Refer to your machine
manual.
The TNC supports the tilting functions on machine tools with
swivel heads and/or tilting tables. Typical applications are, for
example, oblique holes or contours in an oblique plane. The
working plane is always tilted around the active datum. The
program is written as usual in a main plane, such as the X/Y plane,
but is executed in a plane that is tilted relative to the main plane.
There are three functions available for tilting the working plane:
Manual tilting with the 3-D ROT soft key in the Manual
Operation mode and Electronic Handwheel mode, See "To
activate manual tilting:", page 511
Tilting under program control, Cycle
G80 in the part program
(see User’s Manual for Cycles, Cycle 19 WORKING PLANE)
Tilting under program control,
PLANE function in the part
program See "The PLANE Function: Tilting the Working Plane
(Software Option 1)", page 385
The TNC functions for "tilting the working plane" are coordinate
transformations. The working plane is always perpendicular to the
direction of the tool axis.
