ces that are too hard to be machined by other machining processes. The work piece does not heat up during this process as water is used to cool it. "Drilling" is another machining job, which involves the use of a drill or a drill press that Machining refers to the basic process of cutting parts out of a work piece according to predetermined size and shape. Machining jobs are performed using different types of machining techniques such as laser machining, wire electrical discharge machining (EDM), Chemical etching machining, metal stamping machining, water jet machining, and abrasive water jet machining.

Most of the machining jobs are controlled with the help of computer numeric control (CNC) software that guides the cutting equipment along the lines and arcs of a computer aided design (CAD) drawing. The CAD drawing is a three dimensional (3D) graphic representation of parts that are to be fabricated.

Apart from cutting parts from work pieces, machining jobs also include the process of "grinding." Grinding is a process in which a grinding belt or wheel is rubbed against the work piece for removing unwanted material from it. The process is commonly used for fabricating metal pieces that are too hard to be machined by other machining processes. The work piece does not heat up during this process as water is used to cool it. "Drilling" is another machining job, which involves the use of a drill or a drill press that h

"Drilling" is another machining job, which involves the use of a drill or a drill press that has a drill bit for cutting parts from a work piece.

Machining jobs may include "milling," wherein the milling machine resembles a drill press and the cutter looks like a drill bit that goes downwards in the piece to be cut. However, the milling process is less accurate and is preferred less than the turning or grinding machining process.

Machining jobs have enabled manufacturers to design and produce complicated parts used in high tech industries such as aerospace and automobile. An increasing number of machining jobs are now being rendered using environmentally friendly techniques, such as water jet and laser, which are good for the future growth and development of manufacturing industries.
