How accurately the toolpath matches the desired shape depends largely on the number of lines used. To accommodate this, CAM approximates spline and surface toolpaths by linearizing them creating many short line segments to approximate the desired shape. Model box point - Select a point on the model bounding box for the triad origin.ĬNC machine contouring motion is controlled using line G1 and arc G2 G3 commands.Stock box point - Select a point on the stock bounding box for the triad origin.Selected point - Select a vertex or an edge for the triad origin.Model origin - Uses the coordinate system (WCS) origin of the current part for the tool origin.Setup WCS origin - Uses the workpiece coordinate system (WCS) origin of the current setup for the tool origin.Origin drop-down menu offers the following options for locating the triad origin: Use this if your model does not contain a suitable point & plane for your operation. ![]() This uses both the origin and orientation of the existing coordinate system.
