INTRODUCTION
1.1 Basic understanding of the manufacturing processes:
If you look around, you will find many objects that man has made to make life more comfortable. For example, the chair on which you are sitting, the pen you are using, the house you are in, the air conditioner, the lights and other electrical fittings, and so many other things. All these are designed and made by engineers. It can be readily understood that many of these products are made up of many components and very complex. Naturally, the process of making them must be very complex. More importantly different components require different materials and different methods to make. Manufacturing processes teaches you about the different methods and techniques used for making …show more content…

This will help in a proper selection of the appropriate process for any given product. There are many points to be considered for selecting the best manufacturing technique for any product. A systematic understanding and evaluation of the manufacturing processes is required for this purpose. The following are some general points to be considered for evaluating any manufacturing process:

1. Materials: The first point is about what material is to be used for making the given product. The type and properties of this material and its suitability will influence the selection of the manufacturing process. For example, with very hard materials like carbides, it is not possible to use machining. Sintering process is to be selected. Similarly, Polymers are best processed by injection molding and blow molding process.
After selecting and using a process, the properties of the material may be changed. This also should be considered in the selection process.
2. Quality: This tells how good and accurate the products should be. Quality of a product is assessed in terms of the surface quality, dimensional accuracy and stability. Different processes offer different quality levels. Normally, the cost of the process is high for high qualities. A suitable process should be selected depending on the required quality and cost of the
