In this paper, Pedal operated circular saw machine which can be used for industrial applications and household needs is fabricated. It does not requires any specific input energy or electric power. The objective of this model is using the conventional mechanical process which plays a vital role. This project consists of a larger sprocket which rotates with a help of human powered pedal. The smaller sprocket is connected to the plane which is mutually perpendicular to the axis of the larger sprocket is made rotated by using chain drive. The smaller sprocket is rigidly supported by means of shaft and bearing support. The circular saw is mounted on the same shaft where the smaller sprocket is mounted. When the pedal is operated, circular saw rotated which in turn cuts the wooden block material. The main aim is to reduce the human effort for machining various materials such as wooden blocks etc. The power circular saw machine, which runs on human power, works on the principle of the conversion of rotational motion in a mutually perpendicular axis. Importance of this paper lies in the very fact that it is green project and helps us to reduce our electricity need too. Secondly, this cutter can be used and transferred to our working place easily. Moreover, if needed we can generate electricity with our project by connecting it to dynamo, diode and battery.
