Abstract

There are many machining situations where slender tools are used to machine thin walled curve shape workpiece. Such instances are more common in machining of aircraft structural parts. In these cases, the workpiece deflections are quite common which result into surface error on machined components. This project presents a methodology for tool path compensation for effectively machining curve shape thin walled geometries by modifying the tool paths. The cutter compensation method is based on the adjustment of cutter path with respect to the magnitude of surface errors obtained from the preliminary machining with ideal cutter path. The effectiveness of the compensation strategy is then evaluated by measuring the component accuracy and surface roughness.
