The idea behind this research work is to design and fabricate a low cost, compatible, desktop, easily operable and flexible 3 axis CNC router. The selection of the components used for CNC router based on the latest technology and optimum cost. We chosen design of CNC router worked on moving gantry compared to moving bed. Moving gantry design increase workable space, increase movement in z axis. The CNC router machine is fabricated and tested by engraving different design on MDF board of thickness 6mm and area 300x300mm. On the basis of different tests like depth test, speed test and accuracy test of CNC router, it can be concluded that the proposed CNC router is cost effective, flexible and accurate. The achieved accuracy of engraving accuracy is 99% and of depth is 97%. Popularity of CNC router increases rapidly in all areas Popularity of this increase due to impressive capabilities of these machines. By using this we can create the complex shapes which can take long time when the skilled craftsman make the product. In the last few year business is increasing in router system. But many do not know about this machine how they work and what is he do. This is where we want to help. We will discuss and explain the basics of CNC router Systems. In today world the use CNC system technology along with their storage capacity and high computational is increase use in production of products. Now days the most challenging factor how the CNC technology make simple, cheaper and affordable. Objective of this thesis is to design of 3 axis CNC router and fabrication. The structure of CNC router have big part in total cost of the CNC router system thinking of design the structure which is systematic study of drive motors and spindle motors. Maximum travel of CNC router system on x axis, y axis and z axis also which defined approach of machining work volume of the machine material removal also study. We make design and structure which have precision in making the product.CNC router give more flexibility to manufacturing the product. There is also waste produce and error in manufacturing the product.CNC router is used for manufacturing door carving, sign boards, wood panels, interior decoration and exterior by making the product from CNC router repeatability is increase and reduce time. In this thesis we discussed about the design of the CNC on AUTOCAD and proe.cnc router made less in cost and having the good accuracy. Fabrication of CNC router by assemble of different parts of router to make final assemble CNC router we test and analyze the speed of router and cutting accuracy with depth measurement test. We cut the different alphabets on the MDF board of thickness of 6mm and cutting from 3mm to 6mm.we make the CNC router in which the gantry is moving with help steppers motor which are controlled by the computer and microcontroller to give motion to the system. The frame of CNC router is made with the aluminum extrusion and MDF board.
