VERICUT is a true knowledge-based machining system: through the simulation process, it learns the exact depth, width, and angle of each cut. And it knows exactly how much material is removed by each cut segment. With that knowledge, OptiPath divides the motion into smaller segments. Where necessary, based on the amount of material removed in each segment, it assigns the best feed rate for each cutting condition encountered. It then outputs a new tool path, identical to the original but with improved feed rates. It does not alter the trajectory.
