Abstract
Producing square holes in the field of manufacturing, is very common and useful technique. But at same time there is a problem of high cost and complexity in manufacturing. Creating square hole using drill, in addition to have an easier manufacturing is made possible using the special tool. In this paper, curves of constant width are discussed first of all and then, a mathematical model was achieved for the shape of the cam of constant width i.e. Reuleaux triangle. The system design considers modification to existing system for satisfying the requirement of making square hole. We have performed operation on wood and other soft metals. We have identified idea in the research papers for generating square hole by using drilling operation. To make square hole we have to convert circular motion into square motion. The idea is to use Reuleaux triangle which when rotated inside a square, each vertex traces a curve that is almost a square. So, by designing a bit on cam it would be creating square hole on the work piece. During the rotation of the cam, the center of rotation is not fixed and this is the main problem in this mechanism. So there is a need to a non-coaxial coupling to transmit the rotational motion.
