3、问:根据规定,对于R_z、R_y值,图纸上未标注者可以不测,若标注上有,则应检测,那么采用什么样的仪器可以测定呢? 答:目前使用的触针式轮廓仪一般不能按R_z、R_y定义直接测读出结果,只可通过记录轮廓图形进行计算出来。多参数轮廓仪可直接显出R_z、R_y值。轮廓仪测量R_z、R_y参数值范围为0.2～25μm。对于小于0.1μm的R_z、R_y参数值测量,应用干涉显微镜,大于1.6μm者,则应用双管显微镜测量。必须指出,使用光学仪器测量R_z时,要按规定选取样长度和评定长度,即在取样长度
3, Q: According to the regulations, for the R_z, R_y value, the uncalled on the drawings can be unpredictable, if marked, there should be testing, then what kind of instrument can be measured? A: The current stylus profiler General R_z, R_y can not directly read the results of the definition of the definition can only be calculated by recording the profile graph. Multi-parameter profiler can be directly displayed R_z, R_y value. Profiler measurement R_z, R_y parameter value range of 0.2 ~ 25μm. R_z for less than 0.1μm, R_y parameter measurement, the use of interference microscope, more than 1.6μm, the application of double-tube microscopy. It must be pointed out that the use of optical instruments to measure R_z, according to the provisions of the selected sample length and length of assessment, that is, the length of the sample
