Traversing The Reference Points In Tilted Axes - HEIDENHAIN ITNC 530 User Manual

When tilting the working plane, the TNC differentiates between two
machine types:
Machine 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).
Machine with swivel head
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 of your machine—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).

Traversing the reference points in tilted axes

With tilted axes, you use the machine axis direction buttons to cross
over the reference points. The TNC interpolates the corresponding
axes. Be sure that the function for tilting the working plane is active in
the Manual Operation mode and that the actual angle of the tilted axis
was entered in the menu field.
