Abstract :

In the manufacturing industries, various machining processes (turning, milling, drilling etc.) are adopted for removing the material from the workpiece to obtain finished product.  Among the various metal removing processes, drilling is the one of most important metal removing process as compared to other traditional machining processes. Drilling is use for making the hole in the work pieces. Hole making is a most important machining process in manufacturing. During the drilling, the drill rotates and fed into the work piece to remove the material in the form of chips that move along the fluted shank of the drill. Different drilling tools and hole making methods are used for drilling. The selection of different tools and methods depends on the type of workpiece, size of the hole, the quantity of holes, and the quantity of the holes in given time periods. Also, drilling is used as an initial process for many machining operations, such as reaming, tapping and boring. Drilling process is widely used in the aerospace, aircraft and automotive industries.
