Position Display In A Tilted System - HEIDENHAIN TNC 620 User Manual

Setup | Tilting the working plane (option 8)
When tilting the working plane, the control differentiates between
two machine types:
Machine with tilting table
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
relation to the machine coordinate system. Thus if you rotate
the table—and therefore the workpiece—by 90° for example,
the coordinate system
+ axis direction key in the Manual operation mode, the tool
moves in Z+ direction.
In calculating the transformed coordinate system, the control
considers only the mechanically influenced offsets of the
particular tilting table (the translational components).
Machine with swivel head
You must tilt the workpiece into the desired position for
machining by positioning the swivel head, for example with
an L block
The position of the tilted (transformed) tool axis changes in
relation to the machine 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 also
rotates. If you press the Z+ axis direction key in the Manual
operation mode, the tool moves in the X+ direction of the
machine coordinate system.
In calculating the active coordinate system, the control
considers both the mechanically influenced offsets of the
particular swivel head (the translational components) as
well as offsets caused by tilting of the tool (3-D tool length
compensation).
The control only supports the Tilt working plane
function in combination with the spindle axis Z.

Position display in a tilted system

The positions displayed in the status window (ACTL. and NOML.)
are referenced to the tilted coordinate system.
In the optional machine parameter CfgDisplayCoordSys (no.
127501) you can specify the coordinate system in which the status
display shows an active datum shift.
Limitations on working with the tilting function
The Actual-position capture function is not allowed if the Tilt
working plane function is active
PLC positioning (determined by the machine tool builder) is not
possible.
