STUDY AND IMPLEMENTATION OF LEAN MANUFACTURINGTOOL - 5S’1Mr. Nikunj S Patel, 2Mr. Chetan U Patel, 3Dr. Pragnesh BrahmbhattRAI University, Laxmi Institute of Technology, GEC ModasaEmail:[email protected], il.comABSTRACT- Lean manufacturing is anapproach focused on improving quality;reducing variation and eliminating waste inan organization. This research provides aroadmap and implementation of leanmanufacturing tools in manufacturingindustries. The main objective of this paper isthe study, analysis of improvements aboutdifferent manufacturing industries such asmanufacturing of S.G Iron and Alloy CastIron ,Nonferrous Aluminum products,Corrugated boxes Industry, manufacturingheat exchanger and last one is manufacturingof Radiator ,Sealing Gasket etc. where theentire project has been done. Getting theseimprovements, using the initial resources, it isobtained some benefits, adding moreproduction and easiness to work in general.Also there is an improvement in terms ofqualityTo make the project, gather data tools havebeen used. Applying lean Tools and formats,an initial study has been made and thenproposal improvements. After analyze theresults, it is possible to show positiveconclusion using LM as an optimizationmethod, because currently, there is morespace less time used and better quality in thefinal product.These papers represent the one case study inradiator manufacturing company, where the5S’tool implemented. The main Objectivesare decreasing Inventory, more Utilization ofspace, Reduce Wastages.Index term- Lean Manufacturing, 5S’ GapAnalysis chartI. INTRODUCTIONLean manufacturing is a business philosophy thatcontinuously improved all process involved inmanufacturing process irrespective of what typeof product being manufactured. India is one ofthe fastest growing economics of the world. It isprovides highest level of customer servicethrough systematic and continuing searchingnon-value-added activities and wastes andeliminating them. Lean Manufacturing is mainlyadopted by organizations in order to reducewastes and improve the quality of products. InIndia small and medium scales industry has beenvery successfully in improving quality ofproducts, because products are tested at eachevery step in the manufacturing process .Theconcept of lean production arrived to India in themid 1980’s from Japan and united states ofarriving, but it was mostly the larger companiesthat adopted the techniques now the small andmedium companies has started to the Leanmanufacturing concept’s. This gives the extraedge in today’s cost and time competitive insmall & medium scale Industry in IndianMarkets, they are Price, and Quality and deliveryLean enterprise owners can deliver high qualityproducts with low prices.II.

INTERNATIONAL JOURNAL OF ADVANCES IN PRODUCTION AND MECHANICAL ENGINEERING nable foundries is often seen as a set oftools that reduce the total cost and improve thequality of manufactured products the leanmanagement is philosophy is one which targetswaste reduction in every facet of themanufacturing business. Metal casting industriesare actively involved to reduce the scraprejection and rework during the manufacturingprocess of the components. To achieve theseproduction concerns must follow the qualitycontrol procedures correctly and timelyimplementation of the lean manufacturing [4].The lean manufacturing of small industry couldImplementation the philosophy in own contendlean production concept successfully, aninvestigation in two middles sizes industries,India[10]. Value stream mapping techniqueinvolves flowcharting the steps, activitiesmaterial flows, communications and otherprocess elements that are involved with a processor transformation. In this respect, value streammapping helps an organization to identify thenon –value –adding elements in a targetedprocess. Different flow layouts are selected thatreduces the transport time [6], production leadtime and lower –in-process inventory [8]. Theproposedframeworkforleansigmaimplementation need to be validated in differentscenarios for establishing its validity[5] and theultimate goal of this system is to focus onachieving total communication efficiency thatuses Green and lean TQM system[7]. Leanmanufacturing philosophy asks for eliminationof wastes widen in the manufacturing system byfocusing on products value stream andeliminating non value adding activities throughcontinuous improvement [9]. An equipmentreplacement decision problem within the contextof lean manufacturing implementation. Inparticular, we demonstrate how the value streammapping suite of tools can be used to map thecurrent state map the current state of a productionline and design a desired future state. We providea roadmap for how VSM can provide necessaryinformation for analysis of equipmentreplacement Decision problem encountered inlean manufacturing [11].III. CONCLUSION FROM LITERATUREREVIEWSFrom the literature review, we conclude that inthe different direction, the various researchesdone on the lean manufacturing tools andtechniques but there are less number of companyaware about the LM tools and implementation ofthe same. So we implemented the 5s’ concept inthe company.IV. LEAN MANUFACTURING TOOLSAND TECHNIQUESThe core of Lean is based on the continuouspursuit of improving the processes, a philosophyof eliminating all non-value adding activities andreducing waste within an organization. TheValue adding activities are simply only thosethings the customer is willing to pay for,everything else is waste, and should beeliminated, simplified, reduced, or integrated.There are a number of Lean techniques availablesuch as, Value Stream Mapping, VisualWorkplace, Setup Reduction, Cellular/FlowManufacturing, Pull Systems and TotalProductive Maintenance just to name a few;however, it is absolutely essential that Lean isviewed from a total system perspective.Otherwise, either a company risks putting all ofits efforts into the wrong areas, and/or theimprovement process will come to a grindinghalt after the initial project.V.

CONCLUSIONAccording to case study, we conclude that leantools can be used effectively in any kind ofsectors as it is a world class manufacturingtool. The prime objective is to carry outprocess activity mapping for waste reduction.In this study bottleneck product was identified.Further value stream analysis tool wasemployed for identification of wastes in aprocess. The significance of each type of theerror was studied and waste ranking wascarried out. Current state map is plotted to4. sustainable foundries’, China foundryVol.8 No.1assess current status, waste eliminationtechniques are presented and future state mapis also preferred for improvement. The resultof study shows 20% waste reduction in thearea of unnecessary inventory, transportationand waiting. A 5S and Value stream mappingtools can be effectively employed to reducewastes and ultimately improve the process.IV. FUTURE RESEARCHThere is an infinite number of ways ofimplement Lean Manufacturing in theseIndustries. In this project Value StreamMapping is done theoretically but in actualpractice it can be useful. Many industries arenot aware of these tools. RegardingImplementation of 5s it is popular at highermanagement level, but by referring this projectit will be popular in a worker also. By using 5sand Value Stream Mapping moral of workerscan be increased. But this is possible in futureby conducting training program of such type.V.
