dimensions
– in this case you can insert the exact material dimension in al 3 axes.
surface (left from roughing operation) –
the material size can also be automatically
determined as the shell left from the roughing operation. This option is
useful when you plan to continue to work on an object which has been
earlier prepared with the roughing operation.
Pad (distance between material and table)
– here you can insert the actual thickness of the pad.
You can also play with the
Z height and pad thickness
settings in order to
force the tooling at the required height of the material (when e.g. the
material is much height than the model). For more details, see the following
sections.
If the material is much larger than your model, selecting the right project's starting location will
enable you to control the location of the model in your material (see
Machine home position vs. the
project's starting position
).
Location of the model in the material
Should your material be much higher than the height of your model, you can control the height at
which the model will be cut:
•
By entering the total material height as its Z height, the model will be cut at the button of
your material. In this case, the roughing operation will tool off all of the excess material
off the top.
•
In order to have the model cut at the top section of your piece of material, break the total
height of your material into two values: material height and pad thickness. Insert the
model height as your material height, and the remaining part of the actual height of the
material insert as the pad thickness. It is important the combined height of the pad and
material do match the actual height of your material.
Example: in this case, the model is 30 mm high, and the material is 50 mm high.
