This guide will outline the standards used when creating machine simulation files to ensure the user gets the best experience when using machine simulation.
Model detail
To get the best performance within machine simulation, all non-essential bodies should be removed. We define a non-essential body as a part that could not interfere with the physical machining process. Some examples of non-essential bodies would be:
- Nuts & bolts
- Machine feet
- External electrical boxes
- external cabling
To improve simulation performance, it is also worth simplifying the geometry of the machine tool to remove any non-critical features or replace complex features with a simplified primitive. Removing these features will make the document more lightweight and collision checking will be much faster.
Colliding components
To reduce the possibility of collisions being detected on parts that are attached, there should be a gap created between each of the components. This usually means removing bearings &/ linear axis rails as shown below:
Model orientation
To ensure the model works with machine simulation, the CAD XYZ should align with the physical machine XYZ. This will ensure all machine axes move correctly when loaded into simulation
Model structure
Once the model is in the correct level of detail, it should be assembled in a simple hierarchy with a top-level component representing each physical axis and a single static component containing all of the parts that do not move (base, enclosure etc...). Ideally, these components should be at a single level and only contain solid bodies
Model appearance
To provide the best viewing experience, we recommend turning off all construction objects (planes, origins, axes etc..), sketches and images. This will ensure the model looks as natural as possible and the view will not be obscured by any design/construction entities.
Colors
Where possible, we advise using 'light' colors and contrasting colors for each different moveable axis. This will allow the user to easily identify which axis is moving without having to zoom out and see the whole machine. Ideally, the machine should look as realistic as possible, so using accurate machine colors would be best. However, if accurate machine colors are not needed, you can use our Fusion color pallet below:
