like improving the efficiency, productivity, and Ergonomics based caravan designing company. One of the biggest problems for the implementation of lean is the voluminous nature of work and various types of resistance in the early stages. If we ignore such resistance and plow ahead with implementation, the result is likely to be nothing more than superficial improvements. Thus, we have implemented the concept of Lean by providing both flexibility and comfort to the end consumer. Some of the major lean tools are implemented like Poke Yoke, single-minute exchange of die, Kanban, kaizen, standardized work, and takt time.
2. LEAN IMPLEMENTATION 2.1 POKA YOKE Poka Yoke is a Japanese term that means "mistakeproofing" or "inadvertent error prevention". A Poka Yoke is any mechanism in any process that helps an equipment operator avoids mistakes. Its purpose is to eliminate product defects by preventing, correcting or drawing attention to human errors as they occur.
1.INTRODUCTION
In this company before welding, the pipes are bent as required. It takes more time to mark the pipe and check for accuracy every time they bend it. Therefore, introduction of Poka Yoke will help in reducing the time taking to complete the process.
Lean assembling is an administration reasoning zeroing in on the decrease of the seven squanders (Over-creation, Holding up time, Transportation, Handling, Stock, Movement and Scrap) in fabricated items. By disposing of waste (Muda), quality is improved, creation time is decreased, and the expense is diminished. Lean is tied in with getting the right amount while limiting waste and being adaptable and open to change. Lean assembling is a strategy which center around client needs and satisfies it by conveying the necessities at less time with top notch and less expensive expense through taking out a wide range of stowed away squanders that present in the organizations by nonstop improvement
Thus, a stopper is introduced in the pipe bending machine at particular length. This avoids the errors that are made by humans. As pipe to be bent is of constant length in the most cases. This acts as a perfect method of Fool Proofing and has immediate effect on time, as it reduces the time taken to bend the pipe from 250 seconds to 100 seconds.
1.1 EVOLUTION OF LEAN MANUFACTURING The idea of Lean was created by the Toyota leader, Taiichi Ohno (1912-1990). Mr Ohno initially distinguished the seven sorts of MUDA (squander). Mr. Ohno's convictions were formed by his investigation of the Model T Portage (1913) Ceaseless stream in definite gathering, as well as his interest with American grocery stores. In 1913 Henry Portage planned the Model T Mechanical production system so that’ll the cycle was in a similar grouping as the form. Preceding these all-assembling processes (stepping, welding, and so on) were assembled making clump producing. While in the US Mr. Ohno understood that the American Store loading and restocking strategies were
