Planning Machine
It is used to perform almost the same operations as are done on a shaper but jobs of comparatively larger size are machined on the planner.
Grinding Machine
Grinding machine is used to finish the work pieces. Like other machining processes, grinding is also a process of removing metal, but during grinding process comparatively very small volume of metal is removed to bring the work piece to good finishing size.
Milling Machine
A machine tools which is used for producing flat or profiled surface, grooves or slots with the help of revolving multiple tooth cutter is known as milling machine. Milling machine occupies a place opposite to lathe.
Shaper Machine
Shaper is a versatile machine which is primarily intended for producing flat surfaces. These surfaces may be horizontal, vertical or inclined. This machine involves the use of single point cutting tool held in a properly designed tool box mounted on a reciprocating ram.
Machine Shop
The shop where most of the work is performed on different machines is called machine shop. In Machine shop, the raw material is cut, machined, formed or shaped with the help of machines. Different machines used in machine shop are:
1. Lathe machine
2. Shaper
3. Milling machine
4. Planning machine
5. Drilling machine
6. Grinding machine
7. Threading machine

Sheet metal machines and joints
SHEET METAL WORKING MACHINES
For production and heavier works, machines are used to carry out different sheet metal operations. Some commonly used machines in sheet metal shop are:

Pattern Making and Allowances
Pattern is an mirror image of the casting, when it is used with suitable moulding material it forms a cavity called as mould.
When this cavity is filled by molten metal and after solidification we get the desired casting.
Foundry Shop and tools
The place where jobs are prepared by melting and pouring the molten metal into moulds is known as foundry.

Forging (Smithy) Shop
The process of giving a desired shape to metal piece by heating and hammering is known as forging. The metal piece is heated up to a desired temperature known as forging temperature.

Electric Arc Welding
The welding in which the electric arc is produced to give heat for the purpose of joining two surfaces is called Electric arc welding.
Gas Arc welding

Gas welding is the process in which a gas flame is used to raise the temperature of the metal to be joined. The metals are heated up to melting. The metal flows and on cooling it solidifies. A filler metal may be added to the flowing molten metal to fill up cavity made during the end preparation. Many combination of gases are used in Gas welding. But most common of these in oxygen and acetylene.
Welding Techniques
Forge welding:
This welding is done by the black-smiths. In this two similar metal pieces are heated upto the plastic stage in the furnace. Then it is hammered so that a homogenous mixture is formed at the joint. The surface to be joined should be cleaned and made free from any foreign particle this is done by brushing.
Welding Shop
Welding is a process of joining two materials with the help of heat or pressure or by some other means. The cost of welding is very less as compared to other processes and forms a strong joint.
