Manufacturing technology - Coursework Example

The fuel is then compressed and burnt after which it is expelled. Al the fuel is then moved through the cam or pop shaft, this is then moved to the gear and finally to the tires. An automotive piston that is found in the gasoline engine can withstand temperatures of up to 573K. There is a coolant that runs through the engine block and it always has a temperature of 363K. The piston must be cold when it is fixed into the cylinder. The piston can withstand high pressure of up to 10KPa inside the cylinder.

It can withstand different atmospheres; it is able to do well in high latitude as well as low latitude. However in high humidity the engine uses less fuel as compared to low humidity. 1 There are several materials that can be used to make an automotive piston. Some of this include aluminum and copper alloys. The material to be used should be able to withstand high temperatures to start with. This is because the temperature of the engine is too high and so the material has to be able to withstand this without melting or having to expand a lot.

The material also has to be able to withstand high pressure. A material that does not withstand high pressure cannot be used in the engine because of the high pressure that is experienced in the engine. Due to its high melting point and its ability to withstand high pressure and stress, the ideal material to be used is aluminum. . The best however is the assembly of all the piston pins and rods. Before the assembly, the con rod is taken and there bores arranged in a parallel manner. This arrangement ensures that there is no bending of the cones when they are finally in use.

Lubrication is another factor that is necessary. Before the pins are assembled in the cones care is needed to lubricate the pins to ensure that there is less friction between the pins and the cons. For the piston to withstand corrosion and abrasion it needs to be smoothened at the surfaces to make it look more clear and new. For better selection of which type manufacturing process is needed, CES process is used. The physical advantages as well as the cost of the processes are looked into. The software then gives out the best process to be used in terms of the cost and the mechanical advantages that it has to offer.

Different methods contain different advantages but the best one that is used here is the manufacture by the powder rod technology. This process is the simplification of the sinter and the extensional press processes. During the (PPAP) process no heat or even spark should be removed so the forging is done in completely heating and when it is totally enclosed in the dies. Two forms of forging are necessary these are the hot upsetting and the hot repressing. In the hot upsetting, the there is a significant amount of lateral flow.

The production per part approval process is the manufacturing process that was used here. This process has been approved by various agencies in the government as well as many institutions of higher learning. Unlike the (APQP) which has been used in the development and automotives for the many years, (PPAP) has few failures when it comes
