Designing And Manufacturing Of Cobble Stone Cutting Machine

Abstract

Nowadays in Ethiopia and most third world (developing) country cobble stone is the most preferable construction material for road construction and house building. Currently the cobble manufacturing is almost in traditional way, using hand hammer and cutting tools (chisels) which results, wastage, occupational accidents (ergonomic problem), less aesthetic value, improper utilization of human labor resources are the basic determinant problems, thus better way of cobble stone manufacturing method should be scarded for. The general objective of the project is to design and manufacture /provide/ portable and less cost cobble stone cutting and shaping machine which increase the production rate as compared to traditional method replacing the labor force by means of motor power driven machine and demonstrate the working principle of the cobblestone cutting machine. There are a number of basic problems in using the existing (commercial available) cobble stone cutting machine. The problems with this are its size or (huge), Costly, due to its size it is not portable (cannot be easily moved from place to place), and then the manufacturers (micro and small enterprise) or contractors do not like to purchase this machine. This project enables to Increase productivity, develop designing and manufacturing skill, Increase income for micro and small enterprise those who works in cobble stone production activities, Reduce cost by using local available materials, Substitute other import machines
