Solar sintering of Jordanian silica sand

This paper presents the detail description of a solar powered CNC machine. The CNC machine is designed, built and operated completely using solar energy by adjusting the head of the machine using plastic Fresnel lens of 100 cm diameter to focus sunlight to get the melting temperature of various materials, such as: silica sand, glass, plastic, and steel. The proposed concept can be used to build a solar powered factory that is applicable for many industrial sintering applications. The Fresnel lens is used to melt different materials such as silica sand, glass, bricks, and steel. The process of solar powered sintering is fully control through a CAD/CAM program.
