Development of CNC Program for Piston Production

EA Ogbonnaya, BN Nwankwojike, EM Adigio, JA Fadeyi, CN Nwogu


Development of a computer numerical control program for the machining of a piston is a work that involves the casting and machining of a piston on a computer numerical control
machine tool. Aluminum scraps were collected and heated. The molten metal at 7200C was poured into a mould and allowed to cool under atmospheric conditions. A computer numerical control program was written for the turning, grooving and boring of the piston. After cooling, the piston was mounted on a Computer numerical control lathe machine and the program was used to machine the piston. Examination of the dimensional accuracy of the piston showed that the piston with Ø52.553mm had a tolerance value of ±0.004mm which falls within acceptable standard of limit for a piston. Comparison of the piston produced shows that it is of reduced price compared with what is present in the market and with shorter time of production.
