Application of root cause analysis in improvement of product quality and productivity
Abstract: Root-cause
identification for quality and productivity related problems are key issues for
manufacturing processes. It has been a very challenging engineering problem
particularly in a multistage manufacturing, where maximum number of processes
and activities are performed. However, it may also be implemented with ease in
each and every individual set up and activities in any manufacturing process.
In this paper, root-cause identification methodology has been adopted to
eliminate the dimensional defects in cutting operation in CNC oxy flame cutting
machine and a rejection has been reduced from 11.87% to 1.92% on an average. A
detailed experimental study has illustrated the effectiveness of the proposed
methodology.
Keywords: root cause analysis,
cause and effect diagram, interrelationship diagram and current reality tree
