The demand for products having intricate features has increased dramatically so manufacturing industries have to find ways of supplying these products quickly to the costumers. Lot of research and work have been done on sculptured parts using CNC machines. However, there is an urgent need to machine and finish scallops using identification of features in order to reduce machining time. The stereo lithography (STL) file format which depicts data about part geometry is provided by any CAD package, is given as a primary input for generation of the tool path. The output data in the form of cutter location (CL) points is calculated through the machining algorithm by applying different checks such as triangle check, edge check and vertex check and considering various parameters such as depth of cut for roughing pass, side step for roughing and finishing operation. In the present work, features mainly cavities, protrusions and groves are machined in the last in order to save machining time.
