The applicability of a laser triangulation probe to non-contacting inspection

Abstract

SUMMARY This paper highlights the main advantages of non-contacting inspection and discusses the methods adaptable for the dimensional inspection of engineering components by using a compact solid-state laser triangulation sensor on a computer-assisted co-ordinate measuring machine (CMM). The machine used is the bridge-type Granite 80 model of the LK Tools Company. The methods described are equally applicable for similar inspection work by using industrial robots. The motivation for looking at non-contacting inspection methods is also discussed.
