The Use of Lean Manufacturing Techniques – SMED Analysis to Optimization of the Production Process

摘要

Lean is a culture of real and continuous optimization. As a concept of continuous optimization in the midst of limited resources must be practiced continuously as a long term organizational norm. This paper revels why changeover time reduction is important in manufacturing industries and from the various tool and techniques available within Lean manufacturing describes mainly SMED (Single Minute Exchange of Dies) for changeover time reduction and its application in Shaft manufacturing industry. This paper also describes principles, benefits, procedure and practical application of SMED. Theoretical bases are verified in a practical part that describes analysis and design optimization of non-productive time at changeover honing machine in selected shaft manufacturing compaty. The output is the structural design of universal palette and evaluation of productivity due to optimization of operations of time honing gear shafts. The result achieved showed considerable reduction in delay arising out of machine setting time, batch setting time and demonstration delay.
