Visual inspection of components for mechanized assembly.

Analyses (Boothroyd and Redford 1968) have indicated that knowledge of the relationship between parts quality and cost is essential if the performance of a mechanized assembly machine is to be optimized. For mass-production parts, improvements in parts quality are invariably obtained by some form of inspection and a knowledge of the cost of and efficiency of inspection is therefore desirable. Experiments have been carried out for visual inspection to determine the effect on inspection rate and efficiency of changing the quality of the part being inspected and the number, position and type of features of the part which can be inspected. The results of this work are presented in this paper and their significance is discussed. [ABSTRACT FROM AUTHOR]
