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 preset.
After you have selected the desired blank form via soft key, the
control automatically initiates the workpiece blank definition and
asks for the required data:
Spindle axis Z – Plane XY: Enter the active spindle axis. G17 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 preset,
e.g. 0, confirm with the ENT key
Workpiece blank def.: Minimum Y: Enter the smallest Y
coordinate of the workpiece blank with respect to the preset,
e.g. 0, confirm with the ENT key
Workpiece blank def.: Minimum Z: Enter the smallest Z
coordinate of the workpiece blank with respect to the preset,
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 preset,
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 preset,
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 preset,
e.g. 0, confirm with the ENT key
The control ends the dialog.
