摘要：为了提高原材料的利用率，实现合理的工艺改进，介绍原材料消耗工艺定额的定义、分类及其在工艺改进中的重要作用，以YJ2-142型摇架体和其他3种手柄零件的套材为例，对其冲制工艺进行改进探讨，并阐述工时定额对工艺制定方案的影响。指出：原材料消耗工艺定额是确定工艺改进是否科学、经济合理的重要分析手段；提高材料利用率应综合考虑几种零件的生产；在保证冲制质量的前提下，为提高生产效率和经济效益，工序数量应尽可能少；应用原材料消耗工艺定额和工时定额设计工艺，可提高材料利用率和产品质量，降低企业成本。

Abstract:To increase the utilization rate of raw materials for logical technology improvement, introduction is made to the definition,classification and the improtance of the raw material consumption process quota in process improvement with cradle YJ2-142 and three other handle parts as an example,probing is done into the punching process improvement,analysis is done to the hour quota on the process scheming.It is pointed out that the process quota for raw material consumption is an important means in determing whether the process improvement is done in a logical and economic way.Material utilization rate can only be increased by considering comprehensive production of several parts.In the premise of ensuring the quality of punching,the number of processes should be as few as possible for the purpose of improving the production efficiency and economic benefits.Process can be worked out with the process quota for raw material consumption and hour quota to improve the material utilization rate and product quality with low cost.
Key Words:raw material;consumption;process quota;stamping process;punching;layout;cradle; material utilization rate;hour quota
