Abstract

Automobile body is collective assembly of several assembly parts. Function of assemblies is related to one another assembly parts. Assemblies and its actions are derived from the basic mechanical chain mechanisms. These relative motions are most important term to achieve the required function. Precision and accuracy is the sound term of assembly parts for automobile body. Over all efficiency of automobile body function may contributed by even a small element of the assembly parts. Failure of small element in a part may affect function of the body system. Every part of the assembly should meet the basic requirement like strength. There should not be any failure of the product during its entire life time, what reliability engineering talks about. Consideration must be tune to the over all life time function not only at the period of launching. Achieving those strategies can be possible in many ways. Factors to be consider for choosing the right way to meet the requirement which may balance functional constrain and operational conditions. Optimization is term which establishing the balancing of functional constrain and operational condition. This paper deals about the optimization of automobile body part which fails during its function. CAD system made this project simpler to achieve optimized solution for the problem.

Abstract

The 'part mismatch problem' is one of the general quality, problems in automobile assembly production line. Part mismatch affects the production by quality rejection, rework, down time etc. Most of the time part mismatches leads to major functional problem at the assembly section. Kaizen is a method which can control and eliminate such part mismatch problems in automobile assembly production. In this paper, the applicability of kaizen for quality improvement in the production of automobile assemblies with a case study is illustrated. By using kaizen, automobile assembly production line quality problem is solved. Case study about the bracket mismatch leads to brake hose mounting nut offset. This was the major problem of the under body assembly. Step by step kaizen procedure followed to solve the problem by data collection, ischolar_main cause analysis, selection of best solution method, corrective action, documentation and continuing improvement. Kaizen implementation for solving the problem also reflects in the improvement of quality, cost reduction, delivery to customer, morale of the employees and safety. Kaizen was found to be an effective process for improving the quality and productivity. Practical implications of Kaizen can improve the productivity by downtime reduction and quality improvement.
