The tool's trajectory in a CAM program refers to the places where the tool will be during the work. It is important to review it before generating the program for the following reasons
1. analyze the machining strategy and identify which one is better for each piece.
2.Avoid the collision of the tool holder with the work piece.
3.Avoid the shock of the tool with the piece.
4. Prevent the collision of the tool with elements that are not displayed on the CAM such as clamping flanges or screws.
