In the article,the optimum tactics of the regular check to working procedures and the replacement of cutting tools in the course of continious component processing by automatic lathes has been disscussed. For question one,the optimum model of average management cost used for regular check and adjustment of component has been made out by applying the theory of management cost and method of probability statistics,the best designed interval of check and cutting tools′replacement in the working procedure has been obtained. For question two,based on question one,the objective functions has been established,and the optimum tactics of the best designed interval of check and thd replacement of cutting tools has been obtained considering the average loss brought about by unqualified.products at the interval of check and the average loss of machine stop for being misregarded as existing breakdown. The automatic checking and adjusting system the breakdown of working procedures has been designed by using automatic devices,and the algorithm flowchart has been given too Thus the loss of machine stop for being misregarded as existing breakdown would be avoided, and the benefit of working procedure would be increased.
