Clamping the workpiece
Mount the workpiece with a fixture on the machine table. If you
have a 3-D touch probe on your machine, then you do not need to
clamp the workpiece parallel to the axes.
If you do not have a 3-D touch probe available, you have to align the
workpiece so that it is fixed with its edges parallel to the machine
axes.
