Specifying the positioning behavior of the PLANE
function

Overview

Independently of which PLANE function you use to define the tilted
machining plane, the following functions are always available for
the positioning behavior:

Automatic positioning

Selection of alternate tilting possibilities (not with

PLANE AXIAL)

Selection of the type of transformation (not with

PLANE AXIAL)

Automatic positioning: MOVE/TURN/STAY (entry is mandatory)

After you have entered all parameters for the plane definition,
you must specify how the rotary axes will be positioned to the
calculated axis values:

The PLANE function is to automatically position
the rotary axes to the calculated position values.
The position of the tool relative to the workpiece
is to remain the same. The TNC carries out a
compensation movement in the linear axes

The PLANE function is to automatically position
the rotary axes to the calculated position values,
but only the rotary axes are positioned. The TNC
does

not

carry out a compensation movement in

the linear axes

You will position the rotary axes later in a separate
positioning block

If you have selected the

MOVE option (PLANE function is to position

the axes automatically), the following two parameters must still be
defined:

Dist. tool tip – center of rot. and Feed rate? F=.

If you have selected the

TURN option (PLANE function is to position

the axes automatically without any compensating movement), the
following parameter must still be defined:

Feed rate? F=.

As an alternative to defining a feed rate

F directly by numerical

value, you can also position with

FMAX (rapid traverse) or FAUTO

(feed rate from the

TOOL CALLT block).

If you use

PLANE AXIAL together with STAY, you

have to position the rotary axes in a separated block
after the

PLANE function.
