Within VM, objects are<br />
constructed of triangles.<br />
The VM Measure<br />
toolbar provides a middle series of three toggle<br />
buttons that filter the parts of the triangles that<br />
can be selected with the mouse. The left-most<br />
toggle on the VM Measure toolbar switches<br />
between chained (one to the next) and fanned<br />
(one to many) measurements. The rightmost<br />
toggle, when selected, ensures that objects<br />
being measured are always visible.<br />
<strong>Virtual</strong> <strong>Machine</strong> Reference, Menu Bar<br />
Simulation»Stock/Fixtures/Part (CeRun & Gener only)<br />
Measurement information appears in the form of a small HUD (heads-up display) in the simulation<br />
window.<br />
4.3.4 Simulation»Stock/Fixtures/Part (CERUN & GENER only)<br />
This menu bar selection provides the<br />
ability to add rough stock, fixtures and<br />
final parts to the simulation.<br />
This information is stored in a 3D model<br />
(.m3d) file, in the same directory and with<br />
the same name as the verification setup<br />
(.vsw) file. These two files are automatically<br />
saved when the program is completed,<br />
and will be reused on subsequent runs<br />
to quickly reestablish the material conditions<br />
necessary for an accurate simulation.<br />
See “Differences between Part, Fixture and Stock Components” on page 18 for a more detailed<br />
description of how each of these object types are used by VM. In brief:<br />
� Stock: Represents the uncut material at the start of an operation. Stock definitions are<br />
ignored for collision testing purposes unless running with the Material Removal Simulation<br />
(MRS) license option enabled.<br />
� Fixture: Represents the part holding device. Two forms of collision testing are enabled,<br />
depending on whether the fixture is machinable or not.<br />
� Final Part: Represents the final shape expected to be produced. Collision testing is always<br />
enabled, with an addition allowable gouge tolerance on the cutting portion of the<br />
tool.<br />
Objects are maintained in three separate lists, accessible by selecting one of the Stock, Fixture or<br />
Part tabs at the upper left corner of the dialog. For each type, a navigator along the left hand side<br />
of the dialog lists all of the objects defined for that specific type. For example, a fixture might<br />
consist of many parts, such as a base plate, clamps, spacers and so on. Select Import to bring in<br />
the stock, fixture and part definitions from a different part program. Select Export to save the<br />
current stock, fixture and part definitions to a named file for use in a different part program.<br />
