ProcedureThe study models machining error based on curve linearization and scallop height parameters. It then uses computed cutter location (CL) data to compare actual tool trajectories with theoretical curves on sculptured surfaces, assessing deviations. A flexible automation code extracts CL data, imports it into CAD, and projects it onto the surface to compute height deviations for different tool paths and cutting strategies, aiming to find optimal paths.
