Abstract

A roughness measurement tool is used to determine the surface roughness of a roller supported by spaced V-blocks. A pivotably mounted lever arm has one end engaging the roller surface and the other end contacting the probe of a micrometer gauge. The distance between the pivot point and the end of the lever contacting the probe is five times greater than the distance between the pivot point and the end contacting the roller surface. This produces a 5 to 1 mechanical advantage. Hence, the movement of the end contacting the surface of the roller is magnified 5 times by the the movement of the end of the lever arm contacting the probe of the micrometer gauge. The pivot is a slot in the frame with a spring resiliently holding the lever arm therein.
