EXECUTIVE SUMMARY : This project is based on FMEA, an organized approach that guarantees potential process failure modes and their related causes have been considered and tended to in the outline of the procedure. in this report we considered one product to study and take all the aspects into consideration to address main cause of failure of the product and its effects, after it moving further to the improvement system and then show some results based on research material. At the end, reveal a conclusion based on whole report outputs.
PRODUCT : CRANKSHAFT
PROJECT DETAILS : Project in view of crankshaft automobiles FMEA demonstrate in light of value. Breaking down potential reasons for impact on crankshaft . This is based on information got utilizing procedures in view of oral meetings and survey organization on mechanical disappointment of crankshafts from the specialists working in the ranges of car support and crankshafts reconditioning to enhance yields of the projects.
PROJECT METHODOLOGY : Main causes of crankshaft failure
SCOPE :
‘‘Improving the efficiency of automobiles by investigating the procedure FMEA. Decreasing the disappointment happens amid assembling process and expanding the efficiency in the firm‘‘.

Input was given (development team) prior to test runs of new product, test runs were conducted, and the FMEA was continuously updated to reflect new issues that would arise throughout the product cycle. Every conceivable event could not be covered, but the theory is to categorize as many potential failures that may develop during the manufacturing run. The FMEA was a critical component of our production control plans, FMEA’s would be reviewed and updated in accordance with CAR – corrective action reports that would generally originate in response to an internal material rejection or an external customer
The automotive component & Fabrication Plant, ACF, was the original plant site for Bridgeton Industries, a major supplier of components for the domestic automotive industry. All of the ACF’s production was sold to the Big-Three domestic automobile manufactures. Its main competitors were local suppliers and other Bridgeton plants. This company did very well but recently it became less effective when foreign competition and scarce, expensive gasoline caused domestic loss of market share. For boost its selling, it made four criteria, quality, customer service, technical capability, and competitive cost position to evaluate three classifications of products.
Bolt-on counterweights and EVO crankshafts go straight to heat treatment. Bolt-on crankshafts receive their heat treatment process, and EVOs go through a normalization process. After some rough machining and layout, EVOs get counterweights welded on, and then go through the heat treatment process. Heat treatment is a very important area in the manufacturing process. Without properly heat treating, the customer specifications on strength and durability might not be met. The heat treatment could affect downstream processes. After the crankshaft will bend if a proper normalization process was not conducted. The straightness of the crankshaft is also very important. If the crankshaft is bent too much, there might not be enough stock for the machining
Fuel efficiency in automobiles has become a topic of much discussion in recent years in the United States. This is due largely to the environmental devastation that fuel emissions cause, but it is also sparked by the rising fuel costs. Making cars with high fuel efficiency not only saves consumers money, but also will drastically reduce the pollution that is caused by emissions. Today automakers are putting a tremendous amount of effort into making their cars more fuel efficient, both to meet government regulations and to make their car more appealing to the consumer.
Automobiles are American's second largest investment after real estate. It is impoprtant to understand how to keep your car performing at its best.
Failure Mode and Effects Analysis is used to prospectively review a process to determine the potential for errors and potential harm. This allows prospective analysis of the care process.
The success of the automotive parts manufacturing industry is, at its core, derived from the health of the automotive industry as a whole. Conveniently, the
These fuel efficiency automobiles would aid the nation to save on the total energy consumed by the citizens and also reduce on the energy expenses thus fostering growth through the transfer of resources to
The Opportunity of the unit is based on its ability to modify its product despite the two failures. The unit has a very excellent and talented
This paper deals with the production systems of two major leaders in the automobile market. Mass production is briefly touched up on and its advantages and disadvantages are discussed. Lean production is the emerging trend, which talks about minimizing waste and increasing production. We have also thrown light on when to use lean and mass
The above engine is one of the extensively used engines for commercial purpose in India. This engine can with stand the peak pressures encountered because of its compression ratio .Further, the necessary modifications on the piston crown can be easily carried out in this type of engine. Hence this engine is selected for the present project work.
The success of Toyota Company depends on the coordination capacities related to the production of car parts, assembly, store network administration, generation planning, and quality control techniques (Barney & Hesterly, 2008). With the current campaigns on an unpolluted environment, Toyota has fully embraced the production of modern fuel efficient and clean hybrid vehicles. Already, the car has launched the Prius and is working on other new efficient automobiles.
Implementing the restructuring plan, network scheduling method, change in communications and quality control measures will improve the product process at FHE. These changes will also improve costs, employee moral and increase speed and delivery of new products. FHE will continue to see increases profits and maintain their competitiveness in the market. Introduction of the new CAD-CAM system proposed at FHE will increase the efficiency of the
In any modern automobile manufacture, they need highly demand to use plant utilization which very important to success.
This work is done to study the improvement of the quality in automobile industry. This chapter consists three sections named as “Problem definition”, “Objectives” and “Methodology of the study” respectively. The section 3.1 named as “Problem definition” describes the challenge or difficulty that is to be solved. The solution may be achieved after fulfilling the objective by using some sub-objectives that are described in section 3.2 named as “Objectives”. The methodology described in section 3.3 in details. This methodology has been devised keeping in mind the view of “Problem definition” and the “Objectives” that are suggested for the fulfilment of the solution for the problem.
