This report focuses on the manufacturing processes involved in the manufacturing of crank shafts at Bharat forge. The two major manufacturing processes used in the company for making crank shafts are forging and Machining. The function of a crankshaft is to convert a reciprocating linear piston motion into rotational motion .The basic parts of a crankshaft are Shaft, Crankpin and counter-weights. Crankshaft is usually made by steel. Monolithic is a single piece crankshafts are produced in the company.
When the customers put orders to the firm, the details and the specifications of the crank shafts go the Production and Planning Department in the firm. This department then takes help of the Design Department of Bharat Forge in making of the respective dies according to the specifications of the customers. Both Open -Die forging and closed die forging are used in the company for production of monolithic crankshafts. Today more and more customers tend to prefer the use of forged crankshafts due to their lighter weight, more compact dimensions and better inherent dampening. After the for...
Metallix Scotland Limited is a traditional manufacturing company based in Edinburgh. Employing 270 staff, the company mechanizes components for the automotive and aerospace industry. In order to ensure the quality of its products, MSL has relied upon customer Quality Assurance audits. However, it has been decided that the company will gain ISO 9001 accreditation and the customer base have supported this decision and agreed to the move. On the other hand, gaining ISO 9001 requires a lot of commitment and highly trained staff.
The process begins when raw plastic is brought to the plant. This raw plastic is running through certain machines depending on the part ordered. The machine takes raw plastic and molds the plastic into the ordered part. Dye is then added if needed to change the color. One person can run up to 13 machines at a time depending on what machines are running. Every two hours quality checks are put in place. To do a quality check an employee takes a shot of product and searches for defective parts. If a defective part is found the machine gets shut down and maintenance fixes the problem. If a defective product is missed on a quality check a red tag is given. If an employee is given a red tag they must attend a red tag meeting. Furthermore, if an employee receives three red tags the employee is laid
This new form was called hydraulic die-forming. Hydraulic stems from the Greek word hydro meaning water and aulos meaning tube (McCreight, 2004). In today’s society, hydraulic pressing and stamping of dies are used for everything from making small pots and pans to the more extravagant automobile body models. Another use that has recently developed is the more artistic use of, producing form in silver and gold. In order to achieve this smaller, cheaper scale of die-forming experiment were conducted by Richard Thomas and Ruth Girard, which eventually led to the development of the pourable epoxy steel...
For an assembly plant to be so productive materials must be on hand at all times. Every mustang begins with a truck; reels of raw steel weighing in at 30 tons a piece are delivered periodically. Now this raw steel is the moved to a machine that cuts i...
Some of the issues presented above resulted from inefficiencies in the two distinct processes taking place in the same production facility at Custom Molds, namely the Molds Fabrication process and the Parts Production process (Exhibit 1a and b). The two processes serve different customer needs. Mold fabrication, a skill oriented and craftsman-driven process, requires flexibility and quality. Parts manufacturing, on the other hand, involves a more standardized process that competes on delivery and low cost. The margin for parts is also much smaller.
Crank is a book about a young girl who seems to be lost in her own world. She has yet to find out who she really is. This girl has barely hit puberty and maybe being a late bloomer has caused her to make up for the time lost. Like any other teenager she can’t seem to understand why her mom is so strict, and especially why she is so in love with a husband who acts as if he has no backbone. Kristina is her name. Kristina is a young girl; at the age of 17 her life has been pretty average. Having two siblings, a sister who is confused about her sexual orientation, and a younger brother who has all the attention for being the new baby of the family. A stepfather who acts as if he has no flaws;
The case revolves around Bob Marvin, president of the Motor Parts Corporation (MPC), and his executive vice president, AL Shepherd, who held a key senior management position in the company. After Bob, Al had the most important job since most of the line functions reported directly to him. His job required a considerable amount of traveling which he was not able to do lately because of his wife’s illness. Al 's wife, Ruth, was suffering from a malignant brain tumor due to which he was spending more and more time away from work to be with her.
A wise man once told me “With any engine project, a solid foundation is necessary” (Jewett). Racing has been a major part of my life ever since I was little. While growing up, my uncles working on cars and racing together has impacted me. When I was little, I watched my uncles race, and it made me want to race when I got older. However, the instructions for rebuilding a twenty-three-hundred motor include the type, bottom end and the head.
The engine block is known to be the largest piece of metal in a car and also one of the most important part of the engine in which all other components such as the cylinders and pistons are fitted into it and also it contains small holes which act as passage for circulating fluid coolant around the engine to regulate/control the engines temperature. The engine block is where the combustion energy is then transmitted to mechanical energy by the rotation of the crank shafts which then cause the up and down rotation of the pistons which drives the propeller/transmission system that moves the car. In previous engine block models of cars, most were made of iron material, but nowadays engine blocks are manufactured from lightweight aluminum alloy materials to reduce the weight of the car which contributes in good performance (This is mainly found in sports cars), also the cars which have aluminum engine blocks consumes less fuel by producing less emission than those which have iron engine blocks .But in general view ,most of the cars use iron engine blocks because they are cheap...
Anybody and everybody can become an industrial machinery mechanic; especially, those who are passionate about getting their hands plastered in motor oil, grease, and other mechanical lubricants. These people will more than likely be ecstatic about getting into industrial machinery mechanics. They need to be able to put in one hundred ten percent of their effort into becoming an industrial machinery mechanic. An industrial machinery mechanic’s overall objective on the job is to stop a mechanical error before it happens. An industrial machinery mechanics are often caught repairing, maintaining, and fabricating machinery.
Advancement of processing techniques in late 1960s and early 1970s led to the fabrication of modern duplex steels. Introduction of vacuum and argon oxygen decarburization (VOD and AOD) was the main factor that led to this massive development in duplex steels during this period. By the advancement of these techniques it was possible to achieve steels with low carbon content mixing with high nitrogen and chromium contents in balance with austenite and ferrite. This eliminated lot of shortcomings in old duplex steels. The alloy content provided a resistant to corrosion while duplex microstructure contributed to prevent chloride stress cracking under severe conditions. And these duplex steels possessed good weld ability also.
Bores can vary in diameter and form, from bigger piston bores in motor cylinders to rather small bores in fuel injection systems. Quality parameters for these bores are form and geometric accuracy as well as surface roughness and structure. All requirements can economically be met by using the honing process as the final finishing operation for readymade bores. Honing is an abrasive machining process using abrasive grains usually made of diamond or Cubic Boron Nitride (CBN) in metallic bonding. During the process three movement components, namely an axial movement along the bore axis, a rotational movement around the bore axis and the feeding movement of the honing stone, are combined. The feeding movement of the honing stone is induced by an axial movement of the feeding cone, which is translated into a radial movement of the honing stone at the interface between honing stone and work piece. The feeding movement is decisive for the results of the honing process. For a regulation of the process that enables high process stability and repeatability as well as good quality results from the first part it is important to know about the forces in the feeding system of the
The group is also one of the largest manufacturers of small and medium sized steel forgings and the second largest forgings manufacturer in India.
These procedures and practices are used both by GM and by their vendors. The policies vary from layered inspections, statistics, process failure modes, effects analysis and control plans (Drew, 2011). All quality measures produce a graded system of quality management utilizing quality tools. An example of quality control test is that of speedy response wherever dilemmas are resolved quickly and immediately throughout visual management. Individuals responsible for specific tasks are kept accountable for some corrective actions that may subsist. What General Motors did was ignore this quality measurement when it was dealing with the problems of the Chevrolet
Honda has established a program for its suppliers to strive for improvements in order to meet Honda’s requirements. The goals of the BP program are to improve the relationship between Honda and their suppliers, reduce manufacturing costs, and eliminate product defects. They accomplish these goals by focusing on 5 key areas: Best Position, Best Productivity, Best Product, Best Price, and Best Partners (Bounds and Arnold).
