46 First Steps with the iTNC 530
1.3 Programming the First Part
Define a workpiece blank
Immediately after you have created a new program, the TNC starts the
dialog for entering the workpiece blank definition. Always define the
workpiece blank as a cuboid by entering the MIN and MAX points,
each with reference to the selected reference point.
After you have created a new program, the TNC automatically initiates
the workpiece blank definition and asks for the required data:
U Spindle axis Z - Plane XY?: Enter the active spindle axis. G17 is
saved as default setting. Accept with the ENT key
U Coordinates?: Smallest X coordinate of the workpiece blank with
respect to the reference point, e.g. 0. Confirm with the ENT key
U Coordinates?: Smallest Y coordinate of the workpiece blank with
respect to the reference point, e.g. 0. Confirm with the ENT key
U Coordinates?: Smallest Z coordinate of the workpiece blank with
respect to the reference point, e.g. -40. Confirm with the ENT key
U Coordinates?: Largest X coordinate of the workpiece blank with
respect to the reference point, e.g. 100. Confirm with the ENT key
U Coordinates?: Largest Y coordinate of the workpiece blank with
respect to the reference point, e.g. 100. Confirm with the ENT key
U Coordinates?: Largest Z coordinate of the workpiece blank with
respect to the reference point, e.g. 0. Confirm with the ENT key
