摘  要

组合机床是一种高效率专用机床，有特定的使用条件，不是在任何情况下都可以收到良好的经济效益，在确定设计机床前，应该进行具体的经济技术分析。加工同一个机械产品的零件，通常会有很多种工艺方案，进行加工工艺设计，不同的方案会有不同的经济效果，影响技术经济的因素有很多，有时技术指标先进的方案，经济指标不一定优越，因此，需要对技术、经济指标作综合评价，综合多数的意见，选出优化方案进行经济效果评价，如果满意即可决定。
组合机床总体设计—“三图一卡”①“被加工零件工序图”它是组合机床的设计的主要依据，它是制造使用，检修和调整机床的重要技术条件②绘制加工示意图，它是刀具夹具，多轴箱，液压电器装置设计及通用部件选择主要原始资料，它是调整机床，刀具及试车依据。③绘制联系和运动关系及检验机床各部件相对于位置及联系是否满足加工要求，通用部件的选择是否合适，并为进一步开展主轴箱，夹具等专用部件，零件的设计提供依据。④相对生产率计算卡，它用来反映机床的加工过程，完成这一动作所需要的时间，切削用量，机床生产率及机床负荷率。

Abstract

Portfolio is a highly efficient machine for machine tools, there are specific conditions of use, is not under any circumstances to receive good economic returns, in determining the design of machine tools, should carry out specific economic and technical analysis. Processing products with a mechanical parts, usually have a variety of programmes, various options have different economic effects, the impact of technological and economic factors are many, sometimes technical indicators advanced programmes, economic indicators do not necessarily superior, therefore, need to On the technical, economic indicators for comprehensive evaluation, comprehensive views of the majority, elected Optimization of economic evaluation, if you satisfied with the decision.
