DESIGN, MANUFACTURING, EVALUATION, AND ANALYSIS OF CNC CARVING MACHINE

Industries of the country need automation in different equipment which consumes a plenty of time. One of these systems is CNC carving machine which can provide more output in short span of time. All of the setups in industries regarding carving machines were manually manufactured by road side workshops and there was not a single scientific design regarding this machine. It was a great need to design, manufacture and fabricate. It was also a great need to automate it by design software like Mach 3. Keeping in view its need, it was designed by Solid-Works program, manufactured and fabricated in Machine shop. It was provided with such a spindle which could use different head styles in order to change the cutting tools. It also was observed that this unit had a very low cast as compared to the other similar machines. In this setup the drill machine was used where the cutter had to perform its function. The cutting tool used in this machine was a twist drill bit. The precision achieved through this machine was 0.001 inch. The machining speed achieved in this setup was 1 inch per second with longer life span and capability to perform. In order to perform the function, this machine needed a Mach 3 software which could have different designed programs in it. These files of programs were generated from Aspire software. This aspire program generated the codes of the part which was needed to be carved on a particular work piece, metal plate, wood part or any sort of stone. The design could be obtained from Auto-CAD, Solid-Works, Pro Engineer or any software which can be used to make the mechanical parts. Its infrastructure was divided into three systems, i.e. Mechanical, Software, and Electrical. In its mechanical infrastructure, different components were used as per their importance. Like, framing, guide and drive components had a great importance in this case. For this purpose, lead screw was changed to ball screw in order to eliminate the friction losses and to save energy. There several choices for its drive system according to the structure of this machine. Cast iron material was used because of its rigidity. The guide rods were analyzed and it was noticed that these have a less deflection, good thermal expansion due to long time in working condition and strong enough to bear the vibrations. Electrical System needed its controller, computer and its inner electric parts. This machine was totally based on the computer having Mach 3 in order to get the information for the required output.
