The power tools are tools that are used to simplify the complexity of the human work and also produce the same amount of work in a much accurate and speedy manner when compared to the work done by human effort. The power tools are tools that uses high power source in order to accomplish highly efficient work. The power tools are classified in to two on the basis of their mobility, the stationary power tool and the portable power tool. The stationary power tool as the name suggests is immobile but highly efficient and drive high power motors installed in the tool to accomplish the desired work, the portable power tool is the power tool that drives a lower drive motor and the accuracy of the power tool is slightly compromised.

Rigid band saw is a power tool which uses a continuous band of metal with teeth along the one edge of the metal blade; this power tool is used to cut the various types of work piece, the band saw has a principle of operation that there is a band of metal that lies on the wheels that are rotating on the same plane, the rotating wheels are generally powered by the electrical motor. The various other means of powering the band saw is wind energy, water flow, or animal power.

The applications of the rigid band saw is widely distributed as the band saw is suited for cutting irregular surfaced materials, the various types on cutting applications such as wood cutting, sheet metal working, etc. The rigid band saw is a stationary power tool that moves the blades of the tool in accordance with the desired shape and dimensions of the material. The band saw also uses different type of blades for different materials.

The various rigid band saws operate on different principle of operation, the gravity feed band saw uses the gravitational force for cutting the material as it falls with its own weight with the rotating wheels that cuts material, the hydraulic feed band saw uses the motion of the hydraulic piston in order to move the saw forward while cutting the material, the screw feed band saw uses the screw mechanism in order to move the saw while cutting the desired material.

Thus, various types of saws use different mechanism to accomplish the same work. The most technologically advanced method of implementation of the band saw mechanism is by using the automated band saw in order to have the highest efficiency in cutting the material in the accurate manner forming a work piece of perfect dimension. The automated band saw has a feature of controlling various aspects of the band saws such as the feed rate, fall pattern, part feeding, part clamping, etc.

These are the various characteristics that define the dimensions of the work piece. In an automated band saw the characteristics are controlled using numerical controllers that have computer programs that are used to control the characteristics of the band saw.
