Defining A Workpiece Blank - HEIDENHAIN TNC 320 User Manual

Defining a workpiece blank

After you have created a new program you can define a workpiece
blank. For example, define a cuboid by entering the MIN and MAX
points, each with reference to the selected reference point.
After you have selected the desired blank form via soft key, the
TNC automatically initiates the workpiece blank definition and asks
for the required data:
Working plane in graphic: XY?: Enter the active spindle axis. Z
is saved as default setting. Accept with the ENT key
Workpiece blank def.: Minimum X: Enter the smallest X
coordinate of the workpiece blank with respect to the reference
point, e.g. 0, confirm with the ENT key
Workpiece blank def.: Minimum Y: Smallest Y coordinate of
the workpiece blank with respect to the reference point, e.g. 0.
Confirm with the ENT key
Workpiece blank def.: Minimum Z: Smallest Z coordinate of
the workpiece blank with respect to the reference point, e.g.
-40, confirm with the ENT key
Workpiece blank def.: Maximum X: Enter the largest X
coordinate of the workpiece blank with respect to the reference
point, e.g. 100, confirm with the ENT key
Workpiece blank def.: Maximum Y: Enter the largest Y
coordinate of the workpiece blank with respect to the reference
point, e.g. 100. Confirm with the ENT key
Workpiece blank def.: Maximum Z: Enter the largest Z
coordinate of the workpiece blank with respect to the reference
point, e.g. 0. Confirm with the ENT key. The TNC concludes the
