What Is Degree Of Freedom In Tool Design? Explanation With Image

The degree of freedom defines as the capability of a body to move. Consider a rectangular box, in space the box is capable of moving in twelve different directions (six rotational and six axial). Each direction of movement is counted as one degree of freedom. i.e. a body in space has twelve degree of freedom.

Above figure shows a body in space and its possible direction of movement. The body can move two directions along the each axis of three mutually perpendicular axes; also can rotate about this axis either clockwise or anticlockwise. There are twelve degree of freedom for a body in space.

In machining process, in order to attain specific results, the degree of freedom is constrained by using work holding devices, jigs and fixture and locating devices.
