Design and Fabrication of a Pedal operated cutting machine

Abstract

The present trend of engineering focuses on expending little effort and expecting maximum mechanical advantage. The simple conventional machines have proved to be more efficient in this area. As the Technology advances, these simple machines will be coupled with electrical, mechanical, solar drives to extract more work. Such equipments are used from household arena to industrial field also. The conventional wood cutting procedure using Tenon saw or wood saw requires more time and more human effort. An attempt to improve the speed, feed, accuracy with less investment will be tried to accomplish in this present project work. The design and fabrication of prototype wood cutting equipment operated with manual source will be under taken in this project. The concept is to cut wood work pieces by pedaling operation with less human effort and comparatively in less time. The principle involved in this equipment is the Rotary motion of pedaling operation (or electrical powered operation) will be converted to the Reciprocatory motion of the shaft attachment. This attachment shaft will be bolted with a hacksaw frame fixed with wood cutting blade. There will be a provision on the work table to measure the length of the work piece to be cut or retained. This can be achieved by fixing a steel rule on the work table by which the time delay for measurement can be avoided.
