Workshop: It is the shop (or place) where some physical useful work has been performed for manufacturing different types of products. To execute this work, different types of shops are required which are explained here.
For different types of manufacturing processes, different types of shops are required :
Fitting Shop: In this shop, different parts of a product are assembled to get the final shape of the product. The following operations are performed on the parts of the job before assembling: filing, drilling, tapping, cutting, etc. Surface finishing is maintained by Filing operation. If we require to make a hole in the parts of the job, we have to perform drilling operations. Making internal threading is called Tapping. For getting the required shape to the job piece, if it requires to remove some parts of the job piece, we have to go for cutting operation. With the help of, ‘Hack-saw” this operation is performed. Carpentry shop is also used for making furniture. Timber is the material used in the carpentry shop.
Casting shop: There are some design setups where we can make the mold with the help of a pattern. The pattern must look like the final product. So, the pattern is the replica of the final product. Mold is a cavity within which hot molten metal is poured. This mold is prepared with the help of a pattern. So, the shape of the mold is also the same as the shape of the final product. When the mold is filled up with the hot liquid molten metal, it is kept for few hours for cooling. After a few hours, the molten metal inside the mold becomes solid. This solid takes the shape of the mold. Then, this solid metal is separated from the mold and thus we get our required final product.
Forming Shop: Sheet metal works are performed in this shop. If we want to manufacture products of different shape of sheet metal, deformation of sheet metal with the help of Die and Punch is performed by applying pressure to get the shape of the final product. This process is called Forming process.
Machining shop: In this shop, machining operations are performed. Machine tools and cutting tools are used to manufacture the products. There are two types of machining processes – conventional machining and non-conventional machining process. In conventional machining, we use Lathe machine, Shaping Machine, Milling Machine, Drilling Machine, etc, whereas, in non-conventional machining, we use an electron beam melting process (EBM), Laser beam machining(LBM), computer numerical controlled (CNC), etc. In a conventional machining process, the size of chips is large and tool life is less compared to the non-conventional machining process. Also in the conventional machining process, direct contact exists between the workpiece and cutting tool.
Welding shop: It is a joining process by which two metals are joined together by applying heat or pressure. In some joining processes, heat plays an important role and in some joining processes pressure plays an important role. In some welding processes, base metal and electrode both melt. The filler material may also be added to the joint to form a pool of molten metal which is known as Weld Pool. Two metals can be joined by Soldering and Brazing also, but in these cases, low temperature is involved and base metal does not melt. So, the use of filler material is compulsory in Soldering and Brazing processes.
