摘　　要：为了实现硬质合金球的精密加工,采用ATmega128嵌入式微处理器,完成了双转盘精密球体研磨机批量加工控制系统的硬件设计;针对新型的成球运动方式的两个主要参数(转速与压力)进行了精确的控制;采用专家数据控制系统,有效地排除了人工操作的不稳定性,进而保证了批量加工精度和质量的高一致性。实践结果证明,使用该控制方法,取得了良好的控制效果,且实现了产品化。In order to realize high precision processing of hard alloy sphere on rotated dual-plates lapping machine, a control system based on ATmega128 was used to gain processing in batches of lapping machine for precision hall. Aiming at the new pattern of sphere-shaping 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.
