Defining the blank form
If you wish to use the TNC's 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 millimeters long.
The ratio of the blank-form side lengths must be less than 200:1.
MIN and MAX points
The blank form is defined by two of its corner points:
• MIN point: smallest X, Y and Z coordinates of the blank form, entered
as absolute values.
• MAX point: largest X, Y and Z coordinates of the blank form, entered
as absolute or incremental values.
Fig. 4.13: MIN and MAX points define the
blank form.
