Consider the solid model design of piston picture (a). You have been assigned a task to manufacture this piston based on the following methods:- a. Sand Casting b. Any other manufacturing method of your own choice c. Draw the complete engineering-based comparison between the adopted method of your own choice and sand casting for manufacturing the piston. Your comparison must include the effectiveness of manufacturing method, stresses-based analysis in manufacturing methods, product finishing, time laps for completing the product, cost effectiveness of methods, labor cost analysis. d. How can you measure the surface roughness of the piston surface highlighted in picture (b), based on your previous knowledge of manufacturing processes? You must have to mention the equipment by which you will measure its roughness and write the accuracy level. You must draw a valid reason for selecting that equipment. Take the dimensions of piston at your own but take more realistically.

(a) Sand casting:
It is a one of the easiest, cheapest method of manufacturing by which almost all kind of pattern having internal and external cavity can be formed easily. This method can be also used to manufacture the piston.
in sand casting, there is pattern which makes a cavity of sand into which molten metal is pored and metal takes the shape of piston after solidification.
(b) Milling:
A milling is a method of machining that can also be used to design the piston.in a machining operation, there are some cutters which rotates continuously and removes the material from the work piece.
milling is a method that can perform many operation. milling machine can be vertical or horizontal.
