测量的精度,不仅对工程和工业产品质量起着监督和保证作用,而且往往还是工程成败,产品质量优劣的一项决定因素。当前,大力探讨新的检测原理,总结和推广既符合国家“形位公差”标准定义,又简便易行的检测方法;为对国家标准定义加深理解,使其测试手段、测量方法和数据计算符合国家形位公差标准要求,并获得接近真值的被测零件尺寸。下面就谈谈具体检测方法: 1.方箱与直角尺互检法: 将直角尺短工作面固定在方箱一工作面上,并调整直角尺窄工作面(横
Measurement accuracy, not only on the quality of engineering and industrial products play a supervisory and assurance role, and often the success or failure of the project, product quality is a determining factor. At present, vigorously explore the new detection principle, summarize and promote both the national “form tolerance” standard definition, but also simple and easy detection methods; to deepen understanding of the national standard definition, the test means, measurement methods and data calculated in line with National form tolerance standard requirements, and get close to the true value of the measured part size. Here to talk about the specific detection methods: 1. Square box and square mutual inspection method: the rectangular face short rectangular face fixed in a square face, and adjust the narrow square rectangular face (horizontal
