Select the unit of measurement used in the program, for example
millimeters (G71), conclude the block.
Defining the blank form
If you wish to use the graphic workpiece simulation you must first define
a rectangular workpiece blank. Its sides lie parallel to the X, Y and Z axes
and can be up to 30 000 mm long.
The ratio of the blank-form side lengths must be less than 84:1.
MIN and MAX points
The blank form is defined by two of its corner points:
• The MIN point — the smallest X, Y and Z coordinates of the blank form,
entered as absolute values.
• The MAX point — the largest X, Y and Z coordinates of the blank form,
entered as absolute values or incremental values.
