Different types of gears are manufactured in the company. Some types are cam shaft gear. Idler gear, fuel pump gear and fly wheel ring gear. The customers used these gears in tractor and fly wheel ring gear is used in car. In our case study idler gear was chosen for the implementation of DMAIC methodology. This problem will be tackled by implementation the Six Sigma DMAIC methodology. Failure to achieve the required outer diameter according to tolerance is the problem. Idler gear is the most critical component in the tractor. It is used with the combination of cam shaft gear and fuel pump gear. The purpose of these gears is to transmit the motion to the wheel. Failure to achieve in between outer diameter according to tolerance is the problem. The required outer diameter of Idler gear is 233.40 mm with a tolerance of ± 0.05 mm. So the outer diameter of the idler gear must to be between 233.35 mm and 233.45 mm. In past Six Sigma was implemented belt based training structure, so it was most expensive approach. Today we can implement DMAIC methodology of Six Sigma with less cost. In this background, an attempt was made to find out the root causes of defects in idler gear by employing Six Sigma DMAIC Methodology. The Sigma level of existing process is just 1.22. We was determined to the root causes of the defects in gear and made some suggestions for the company. These root causes are CNC lathe machine, cutting tool geometry and choice of the best combination of speed and feed rate. For that purpose we have designed an experiment and based on results we can choose the optimal combination. By implementing these suggestions company will be able to overcome the defects in idler gear and others as well. After reduction of these defects the sigma level will be increase by improving the process capability. DMAIC methodology is an effective tool for breakthrough improvement. This will enables the company to spend less cost to obtain Six Sigma level quality. Hence, DMAIC is the promising methodology to obtain maximum productivity and efficiency with less cost.Item Balancing of product mix assembly line using sub assembly parallel shops via computer sim(UMT, Lahore, 2016) MUHAMMAD SALMAN, USMAN ALI S and AFDAR NAWAZAssembly line balancing is extremely vital in automobile industries, where different models of a same product are produced and assembled on a single assembly line.

The main aim of the current thesis is to examine the product and the main reason of neck & base crack issue in the final product. This can be done by analyzing the reaction of different sections & plant of the factory. While focusing on the period between 2015 and 2016 the thesis traces the evolution of the neck & base crack issue dating back to 2010. The thesis also shows how the conditions will affect the quality of raw material & final product. In parallel, the thesis explores the quality defects on preforms & bottles after getting manufactured. This was strongly indicated from the 2010 that this problem will increased and definitely will target the market value and sales. To highlights the main reason of problem, humidity was concluded as the main reason for this issue. The central argument of the thesis, therefore, is effect of humidity on preforms & bottles and the after products. The thesis contends that by controlling the humidity we can control this issue of neck & base crack because it mostly occurs during the humid season from June to September. Getting data from all warehouses & by noticing all the parameters suggested by original equipment manufacturer the data was collected to investigate the reason behind this serious issue. Also, help from the technical team of the original equipment manufacturer was taken. The site visits were arranged so that they can have a brief and comprehension visit of the plants and to find out the main reasons behind the fault. After all the investigation and more than 1 year of hard work, they were all able to come to a conclusion that this problem was occurred, more or less, due to the factor of humidity. Finally, this thesis observes that the main problems lies in controlling the environment on all the plants like injection molding plant where preforms are manufactured & blow mold where bottles and final products are being manufactured and also the warehouses where the final product is kept. Moreover, this thesis also observe the wrong parameters used in manufacturing. After all the investigation, completion of action plans and remedies taken the company was able to reduce the defect to 95% expectedly. This could be a big achievement.Item Importance of occupational health and safety and barriers to its implementation(UMT, Lahore, 2016) HUSSAIN AHMAD, SUMMIYA NIZAMI and HUSNAIN HAIDERInjuries in the workplaces are a matter of concern for all organizations on ethical, economic, professional and legal grounds (Mark A. Friend, 2007). Occupational Health and Safety (OHS), also referred to as Occupational Safety and Health (OSH), is the field concerned with safety, health and welfare of people employed at any workplace. The main objectives of OHS include building, nurturing and sustaining a safe and healthy environment at workplaces. At some places around the globe, the scope of OHS is extended to included co-workers, family members, customers, and many other stakeholders who might get affected by the work environment. Workplace conditions are typically regulated by bodies designated by the legislature in place. Either common law practices alone or the statutory regulations drawn upon common law practices lay out the guidelines in this regard (Foster, 2012). Organizations in Pakistan are also bound by law to ensure a safe working environment for the people engaged at various workplaces. This study has been undertaken to observe the level of implementation of OHS in automotive parts manufacturers sector in Pakistan and to identify the barriers that companies face in their efforts to implement OHS in their workplaces so that improvement measures to be taken in the wake of the said barriers could be proposed.Item Improving productivity using lean manufacturing tools at GMS forgings Lahore(UMT, Lahore, 2016) HAIDER MASOOD, FARHAN SHAH and MUHAMMAD AJMALThis project presents an industrial case wherein the “Lean Manufacturing Concepts” have been applied for the objective of process improvement.

Currently about 2.7 billion people in developing countries rely on biomass including wood, charcoal, tree leaves, crop residues and animal dung for cooking. In Pakistan, nearly 66% of the population cook’s food using different biomass fuels. The situation is not likely to change in the near future due to the high cost of LPG that makes it unaffordable for poor people across the Pakistan. The biomass burning devices used for cooking are known in the literature by various names such as cook stoves, wood-burning cook stoves or biomass cook stoves. There is a need to focus on drastic reduction in the costs of these stoves through innovative designs and by exploring the possibility of using locally available materials. We have used rice husk as biomass and made a special reactor fabricated from local machines and local materials in order to decrease the cost of stove. We have achieved high thermal efficiency from our stove using gasification process which requires limited amount of air that has been provided by a DC fan that is also connected to solar power in order to charge the battery so that stove can be operated at any time even during electric load shedding. By-product is a bio-char which can be used as a fertilizer because of enrichment of essential minerals like potassium and nitrogen. We have designed different models of our stove using Creo Parametric 2.0 designing software and implemented different design factors in our stove for better handling, operating and for better safety purpose. We have won “Rector Award for Entrepreneurial and Innovation” for our final year project “Solar Powered Dry Biomass Fueled Stove”. We also compete for Pakistan Startup Cup 2016 and secured a position among top 25 projects all over the Punjab.
