Understanding The Roughness Parameter Called “Max”

A quick glance at a finished surface will make you think it looks perfect. However, imperfections are bound to be there, and they may come in the form of valleys and hills, varying in both spacing and height. Roughness as that is called, exists in the form of a succession of minute irregularities. This may be caused by its own finishing process, such as the utilization of a single point tool. Surface roughness tends to be both directional and uniformly spaced. If surface roughness was a result of cylindrical or straight grinding, the roughness of the surface tends to be irregularly spaced.
