Abstract: In order to realize high precision processing of hard alloy sphere on rotated dualplates lapping machine, a control system based on ATmega128 was used to gain processing in batches of lapping machine for precision ball. Aiming at the new pattern of sphereshaping movement, two main parameters including rotation rate and pressure were accurately controlled. Using the expert data system, the unstability of the human operation was eliminated. High lapping accuracy for processing in batches was improved. It is proved that, the good control effect is gained and product forming can be realized from the control system.
Key words: precision ball; lapping machine; ATmega128; control system
