在全面质量管理工作中,提倡上道工序为下道工序服务、下道工序是用户。工序间首要的服务项目就是恰当的工序间余量。很明显,过多的余量影响下道工序的经济效果,余量太少要出废品,工序余量过多,不仅费工时,甚致难以继续加工。如研磨、铰孔等工序,只能在较小的余量范围内进行。由此看来,工序间余量直接影响工件质量和经济效果,应以适当
In total quality management work, we advocate the process for the next process service, the next process is the user. The first service between processes is the right balance between processes. Obviously, excess margin will affect the economic performance of the next process. If the margin is too small, waste products will be left with too much allowance. This will not only make it difficult for workers to continue processing but also work time. Such as grinding, reaming and other processes, can only be carried out in a smaller margin. Seen in this light, the balance between processes directly affect the quality and economic effects of the workpiece should be appropriate
