There are two functions available for tilting the working plane
■
3-D ROT soft key in the Manual mode and Electronic Handwheel
mode (described below)
■
Tilting under program control: Cycle 19 WORKING PLANE in the
part program: see „8.7 Coordinate Transformation Cycles“.
The TNC functions for “tilting the working plane” are coordinate
transformations in which the working plane is always perpendicular
to the direction of the tool axis.
When tilting the working plane, the TNC differentiates between
two machine types
Machines with tilting tables:
■
You must tilt the
workpiece
into the desired position for
machining by positioning the tilting table, for example with an L
block.
■
The position of the transformed tool axis
does not change
in
relation to the machine-based coordinate system. Thus if you
rotate the table — and therefore the workpiece — by 90° for
example, the coordinate system
does not rotate
. If you press the
Z+ axis direction button in the Manual Operation mode, the tool
moves in Z+ direction.
■
In calculating the transformed coordinate system, the TNC
considers only the mechanically influenced offsets of the
particular tilting table (the so-called “translational” components).
Machines with swivel heads
■
You must bring the
tool
into the desired position for machining by
positioning the swivel head, for example with an L block.
■
The position of the transformed tool axis
changes
in relation to
the machine-based coordinate system. Thus if you rotate the
swivel head — and therefore the tool — in the B axis by 90° for
example,
the coordinate system rotates also
. If you press the
Z+ axis direction button in the Manual Operation mode, the tool
moves in X+ direction of the machine-based coordinate system.
■
In calculating the transformed coordinate system, the TNC
considers both the mechanically influenced offsets of the
particular swivel head (the so-called “translational” components)
and
offsets caused by tilting of the tool (3-D tool length
compensation).
