求翻译：一个好的结构不但应该达到设计要求，而且要有好的机械加工工艺性，也就是要有加工的可能性，要便于加工，要能保证加工的质量，同时是加工的劳动量最小。设计和工艺是密切相关的，又是相辅相成的。对于设计阀体的加工工艺来说，应选择能够满足内花键加工精度要求的加工方法及设备。除了从加工精度和加工效率两方面考虑以外，也要适当考虑经济因素。在满足精度要求及生产率的条件下，应选择价格较底的机床。是什么意思？

A good structure should not only meet the design requirements, and have good mechanical processes, is to have the possibility of processing, ease of processing, to be able to guarantee the quality of processing, while processing minimum amount of labor. Design and technology are closely related, the
