工件表面粗度的测量,出于功能、经济和审美的理由,可按不同的测量方法使用高灵敏度仪器在生产车间或实验室进行。通常使用触针式轮廓仪,这种仪器以二维表示法提供放大了的轮廓截面。但这种触测法也有它的缺陷,总之,应根据具体的测量条件选用测量仪器和 The measurement of the roughness of the surface of the workpiece, for functional, economic and aesthetic reasons, according to different measurement methods using high-sensitivity instruments in the production workshop or laboratory. A stylus profiler is often used, which provides an enlarged profile of cross-section in two-dimensional notation. However, this method also has its own touch-detection defects, in short, should be based on the specific measurement conditions selected measuring instruments and
