Some CAM vendors refer to optimized software as the software best suited for the types of machines, processes or parts being programmed.

On one hand, having CAM integrated with the CAD program may be argued as the most effective and optimum way to work. Conversely, CAM programmers may be better served by selecting specialized software for the type of task, instead of relying on a solution integrated with CAD. Often both arguments are used by the same CAD/CAM vendor depending on the situation.

However, optimized software should not be confused with optimization software. But even narrowing the scope to NC program optimization software the meaning remains unclear. Some CAM vendors refer to NC program optimization as the ability to automatically determine how much stock each cutter can machine without gouging the part. Others refer to optimization as improving the trajectory of the cutting motion by using continuous tangent motion rather than sharp, interrupted movements.

Some define optimization very loosely as visualizing the machining process and imagining how to improve it. And then there is process analysis software that combines workpiece material properties and machine dynamics to predict forces, temperatures, etc. caused by a given toolpath. The predicted results can then be analyzed to identify opportunities to manually adjust portions of a toolpath.
