Abstract

Objective: To examine the existing system of a production line in a shop floor of steering gear box manufacturing industry and to improve the productivity using lean methodology without much affecting current working systems. Method/ Analysis: An extensive range of lean manufacturing tools are available to take care of all kinds of issues faced by different manufacturing industries. It also helps for successful cost reduction of the manufacturing component and to assure the quality of manufacturer and customer. Findings: The critical Non-Value added Activities (NVA) were recognized and probabilities required for development has been recognized. Value Stream Mapping (VSM) has the reputation of finding waste during manufacturing and business process which facilitate to identify and remove or stream the value added steps and to eliminate the non-value added steps. Application/Improvements: After accomplishment of appropriate lean tools, it was found that the total setup time was condensed by about 180 minutes and cycle time was condensed by about 98 minutes which ultimately reduces the lead time and increases the productivity.
