- 16. LASER Marking It isachieved by moving a low-powered beam slowly across the material using a method called discoloration, which creates high-contrast marks without disrupting the material. LASER heats the material, causing oxidation under the surface and turning the material black. It applies low temperatures to metal to anneal the surface. MNS University of Engineering & Technology, Multan
- 17. LASER Engraving The LASER createshigh heat during the engraving process, which essentially causes the material to vaporize. It’s a quick process, as the material is vaporized with each pulse. This creates a cavity in the surface that is noticeable to the eye and touch. MNS University of Engineering & Technology, Multan

- 28. Motion Control A machineis assembled and Arduino flashed with 'GRBL controller" is used as motion controller of the machine. Testing The completed machine is tested using different techniques, i.e. speed testing, perpendicularity testing and circular testing. The possible error sources are determined and fixed. Budget In this project, a small scale two axis CNC LASER engraver machine is designed and analyze under very limited budget of (40,000 pkr). Structure The most suitable structure frame, the open frame vertical type structure, is chosen. Features Due to accuracy of the machine body parts and precise assembling, the machine achieves the desired precision and repeatability level. It is sufficient to create small features such as letters and graphs with sizes less than 1cm. Conclusion MNS University of Engineering & Technology, Multan
- 29. Heavily rely onthe design of motion controller The best possible solution is using Raspberry Pi as the “PC” terminal of the controller and using a touchscreen as the interface user can easily transfer machine code file into the system using a USB drive Then stream of the machine code into Arduino through another USB port easily.
