2.10.5 Part / Stock Comparison<br />
Comparison between the design part and the inprocess<br />
stock is only available with a MRS (Material<br />
Removal Simulation) license available and<br />
enabled via the SIM button on the GENER and CERUN launch panels. The MRS license provides<br />
the added functionality to compute the effect of the cutting process of the tool on the rough<br />
stock. The resultant shape is called the “in-process stock”.<br />
The left-most of the circled buttons above toggles the display of the in-process stock. The two<br />
buttons to its immediate right toggle the display of Boolean Overcut (gouge) and Boolean<br />
Undercut (excess) material. The gouge and excess calculations are done using an exact comparison<br />
between in-process stock and its associated part. These associations must first be setup using<br />
the “Associated Part” setting in the Simulation»Stock (Ctrl Alt S shortcut) dialog (on page 18).<br />
The Boolean excess and overcut results can sometimes<br />
be misleading, since it can be difficult to judge<br />
the thickness of the excess or gouge material. VM<br />
provides a Simulation»Compare (Ctrl Alt Q shortcut)<br />
color graduated part/stock comparison feature to<br />
address this issue. The comparison colorization<br />
settings are applied only to gouge and excess material,<br />
which must first be enabled by selecting one or both<br />
of the Boolean Overcut and Boolean Undercut filters.<br />
Select the Colorized Boolean filter (second from right<br />
in the circled buttons above) to compute and view the<br />
results.<br />
The comparison is done by sampling the surface of<br />
the gouge and/or excess material, and computing the<br />
shortest distance to the part. The distance is then used<br />
to assign a fixed or graduated color, as defined using<br />
the various options of the Compare dialog. If the sample size is small, or the part very large, the<br />
colorization process may take a long time to compute. The comparison can be cancelled at any<br />
time, in which case the displayed results will be incomplete (but perhaps still useful).<br />
When viewing the gouge material in combination with either the part or the in-process stock, it<br />
helps to select the part with the mouse so that its surface becomes transparent, allowing the<br />
gouged material surface to be seen.<br />
