CIMulator3D software has an upgraded interface and offers clearer visualization with a customizable timeline panel, which effectively is a central dashboard for tool analysis. Tool programs can be verified for size, shape, machine clearance and cycle time estimates. The software provides a realistic and unique view of the material removal process. It also simplifies workflow by doing calculations in the background rather than having users initiate them, including collisions, which are recalculated automatically when machine configuration is changed; material removal rates, which are calculated when a row is shown in timeline to display the MMR graph; and tool balancing, which is calculated automatically when the tool balancing dialog is shown.
