Cutting is a process of machining which uses a cutting tool to remove material from a workpiece. It is used to shape or finish workpieces that have already been formed or hardened. The most common types of cutting are drilling, reaming, turning, milling, and grinding.
Although cutting is usually associated with metalworking, it can also be used on other materials, such as plastics and wood. Its popularity is due to the fact that it is inexpensive and fast, compared to other machining methods. Different types of cutting require different approaches to cutting.
The parameters of cutting are the cutting speed, feed rate, and depth. The cutting speed is the speed at which the cutting operation is performed. This is determined by the type of tool used, the material being cut and the cutting parameters. The feed rate is the rate at which the cutting tool is moved over the workpiece in a given time, and it is mainly dependent on the cutting speed. The depth that is achieved with a given cutting motion can be calculated by the feed rate and cutting speed.
The cutting tool used for cutting is usually either a router, drill bit, or turning tool. Routers are used for cutting softer materials such as woods and plastics, and tend to produce smoother finishes than other tools. Drills are used for cutting harder materials such as metals, and are the most versatile cutting tools because they can be used for both rough and precise cuts. Turning tools are used for cutting curved surfaces and they are capable of producing precise cutting motions.
The type of cutting fluid used is also important. Cutting fluids are used to lubricate the cutting tool and reduce tool wear, friction, and heat generated during the cutting process. The most common types of cutting fluids are oil-based, water-based and synthetic cutting fluids, and diamond or cermet cutting fluids that are used for cutting harder materials.
In addition to cutting parameters and cutting tools, proper safety equipment must be used. This equipment includes safety glasses, a face masks, and protective clothing. The type of safety equipment used will vary depending on the type of cutting being performed.
Cutting is a fundamental machining process that has been applied in many industries for centuries. Its importance cannot be overstated, and its use can be improved by understanding the various cutting parameters, cutting tools, and safety equipment used.
