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 dialog for defining the blank form is initiated with the BLK FORM soft
key (in the second soft-key row).

the blank form
F!!i
The ratio of the blank-form side lengths must be leas than 84:1.
MIN and MAX points
The blank form is defined by two of its corner points:
l
The MIN point-the smallest X, Y and Z coordinates of the blank
form, entered as absolute values.
l
The MAX point-the largest X, Y and Z coordinates of the blank form,
entered as absolute values or incremental values.
