在新型号研制过程中,生产准备周期要求尽量缩短,所以生产准备工作中的拥挤与排队是新型号研制中的突出矛盾之一。以模夹具而言,当模夹具设计完毕后,立即集中于一段很短的时间在工装制造车间投入制造。由于模夹具都是一次性单件生产,所以这时工装制造车间的机工与模夹具钳工到工具室窗口借还工具的次数是相当频繁的。若车间工具保管员少,工人因等待借还工具的时间长而影响生产任务的完成;若车间工具保管员多,工人借还工具不等了,但车间对工具保管员的开支多了,也不经济。在这样的情况下,究竟应设置几个工具窗口才最经济合理呢?据统计,在这段时间里,工装制造车间平均每35秒就有一个机工或
In the new model development process, the production preparation cycle requirements are as short as possible, so crowding and queuing in production preparation work is one of the prominent contradictions in the development of new models. In the case of die clamps, when the die clamps are designed, they are immediately concentrated on a short period of time at the tooling shop. Since the die clamps are all produced in one piece at a time, the number of times that the mechanics and die clampers in the tooling workshop borrow tools from the tool room window are quite frequent. If there are few shopkeepers on the shop floor, workers will affect the completion of the production tasks due to the long waiting time for retrieving the tools; if there are many shopkeepers in the workshop, the workers will not be able to borrow the tools, but the workshop will have more expenses for the custodians of the tools. Uneconomical. Under such circumstances, how many tool windows should be set up to be the most economical and reasonable? According to statistics, during the period of this time, the tooling workshop has an average of one mechanic or every 35 seconds.
