OPTIMIZATION COMPARISON OF ROUNDNESS ERROR IN WIRE- EDM MACHINING BY VARIABLE METHODS

Roundness error can be evaluated perfectly for the by product life after manufacturing, leading the major criteria in assembly errors and vibration control mechanisms. Components with round profiles must have to go for a quality check, different optimal techniques like Least Squares Circle (LSC), Minimum Circumscribed Circle (MCC), Maximum Inscribed Circle (MIC) and Minimum Zone Circles (MZC) are available internationally to validate the error variations in roundness. This paper focuses on roundness evaluation using nonlinear optimization techniques, for the manufactured components in Wire- EDM. The Computer Aided Inspection (CAI) procedures have gained a prominent role in the field of inspection and evaluation of the manufactured parts. In the recent years, the Coordinate Measuring Machines (CMMs) have gained popularity in automated inspection for both online and offline inspection of manufactured components. Present comparison of practical components inspection by CMM with optimal methods
