Evaluation and Improvisation of Overall Equipment Effectiveness in a Sheet Metal Parts Manufacturing Industry

This chapter presents a case study of evaluation and improvisation of Overall Equipment Effectiveness for the machines like CNC Laser Cutting and CNC Panel Bender present in a small-scale industry involved in the fabrication of steel furniture. The calculations and analysis of Overall Equipment Effectiveness for the machines are carried out by measuring the time required for various steps involved during the manufacturing of the parts and also through conversation, interrogation and observations over a period of one week. After the current status of Overall Equipment Effectiveness is known, the lean tools and techniques like Root cause analysis, Six Big Losses, Kaizen and Single Minute Exchange of Die was used. The Kaizen team was formed and was led for four days. Also, the suggestions were implemented with the assistance of the Kaizen team. After the implementation of the tools and techniques again Overall Equipment Effectiveness was calculated and it was found to have improved. Later, the scheduling of the CNC Laser Cutting and CNC Panel Bender was also carried out with the assistance of scheduling software “LEKIN” for further improvement of Overall Equipment Effectiveness.
