Cutting
Cutting is a collection of processes wherein material is brought to a specified geometry by removing excess material using various kinds of tooling to leave a finished part that meets specifications. The net result of cutting is two products, the waste or excess material, and the finished part. If this were a discussion of woodworking, the waste would be sawdust and excess wood. In cutting metals the waste is chips or swarf and excess metal. These processes can be divided into chip producing cutting, generally known as machining. Burning or cutting with an oxyfuel torch is a welding process not machining. There are also miscellaneous specialty processes such as chemical milling.
Cutting is nearly fully represented by:
• Chip producing processes most commonly known as machining
• Burning, a set of processes which cut by oxidizing a kerf to separate pieces of metal
• Specialty processes
Iron cutter is used to cut the metal in the desired shape and size. It reduces the human effort to a great extent. In old days metal cutting saws are used which can cut the metal but the finishing of the cutting metal and dimensions may vary because of unskilled person. To reduce the chances of mistake and to reduce scrap the automating metal cutting machine is introduced which is more accurate and more fast than the saw.
