摘　　要：针对手工倒角劳动强度高、加工效率低的现状,开发了一台自动倒角机,采用基于PLC的控制系统,对倒角工序进行顺序控制,实现连续循环加工,以提高生产效率。该系统可对细长棒料两端同时倒角,并且可以通过触摸屏设定工件直径和切削量,以满足不同直径工件的倒角要求。利用光电开关准确感应工件的位置,通过相关的控制程序自动补偿工件长度误差和送料定位误差,从而实现快速、高效与高精度的倒角。According to the current situation that in manual chamfering machine system labor intensity is high and production efficiency is low,a set of automatic chamfering machine is requested to develop to improve the production efficiency.Therefore,PLC is put into use in the control system.The system can control the process of chamfering machine in sequence and achieve continuous cycle processing.Also it can chamfer the both ends of the thin and long bar stock in the same time.And that to different diameter and cutting output,the value can be set at any moment,so it applies to different dimensions w orkpiece. When the thin and long bar stock is feed,it exits errors w hich are caused by different length and different feed direction In the mechanical equipment,a photoelectric sensor is fixed near the tool to detect the w orkpiece accurately.According to the accurate position,the position error and length error can be compensated.It is proved to have the characteristics of celerity,efficiency and accuracy.
