Abstract :
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
