本文讨论了将表面形貌仪与通用微处理机联机,对加工表面进行数字处理的技术.目前国产表面形貌仪只能测定 R_a一项参数,应用这种技术后,可以作任意参数的评定.作者通过对五种加工表面的各十个形貌参数,进行了编程计算,并对表面作了频谱分析研究.探讨规律,认为这种应用是可行的,效果是好的,可以大大扩大商品形貌仪的功能,从而提高加工表面质量评定工作的水平.同时作者还对表面数字处理中用的三个基本规范:评定长度、取样长度和采样间隔,进行了研究,提出了不同于国内外长期以来所沿用的规范的设想和数据.
This article discusses the surface profilometer with a common microprocessor, the surface of the digital processing technology.At present, the domestic surface profilometer can only measure a R_a parameter, the application of this technology, you can make any parameter assessment The author calculated the ten topographic parameters of the five kinds of machined surfaces and made a spectrum analysis of the surface.It also discusses the law and thinks that this kind of application is feasible and the effect is good and the product can be greatly expanded The appearance of the function of the instrument to improve the quality of the surface quality assessment work level.At the same time, the author also on the surface of the digital processing used in three basic norms: assessment length, sampling length and sampling interval, were studied, different from at home and abroad Norms and assumptions used for a long time.
