5.Select carefully between stocks and integral components.A previously developed components is frequently selected by a designer and his company from the stocks of parts manufactures,if the component meets the performance and reliability requirements and is adaptable without additional development cost to the particular machine being designed.However,its selection should be carefully made with a full knowledge of its properties,since the reputation and liability of the company suffer if there is a failure in any one of the machine's parts.In other cases,the strength,reliability,and cost requirements are better met if the designer of the machine also designs integral with other components,e.g.,gears to be forged in clusters or integral with a shaft.
6.Provides for accurate location and non-interference of parts in assembly.A good design provides for the correct locating of parts and for easy assembly and repair.Shoulders and pilot surfaces give accurate location without measurement during assembly.shapes can be designed so that parts cannot be assembled backwards or in the wrong place.Interferences,as between screws in tapped holes,and between screws in tapped holes,and between linkages must be foreseen and prevented.Inaccurate alignment and positioning between such assemblies must be avoided,or provision must be made to minimize any resulting detrimental displacements and stresses.

5.仔细选择股票和整体部件之间.一个先前开发元件通常是由一个设计师,他的公司的股票,如果组成部件生产符合要求的性能和可靠性,无需额外的发展相适应的特殊费用正在设计的机器.然而,它的选择应该小心地与一个完整的知识,因为它的性质和责任的公司声誉遭受失败,其中任何一种机器的零部件.在其他情况下,强度、可靠性和成本要求,更好地满足如果设计师设计的机器也与其它部件,如积分、齿轮、伪造或积分在集群轴.
6.提供准确的定位和互不干涉的零件组装.一个好的设计提供正确的定位和容易组装与维护.肩膀和飞行员面给精确定位没有测量在assembly.形状设计可以使零件组装或不能出现在了错误的地方.之间的干扰,轻轻地螺丝孔螺丝孔之间的联系,轻之间必须预见和预防.准确对齐和定位之间必须避免总成必须作出规定,或减少到最低产生有害的位移和应力.
