This thesis describes the process of designing and manufacturing a CO₂ laser engraving machine.
The project consists of several phases, including planning, selecting components, procurement, and assembly. Various technical disciplines are involved, primarily electrical engineering and mechanical engineering. Knowledge from both fields was utilized, especially during the planning and assembly phases.
In the initial phase, I envisioned the design and created an electronic CAD model of the machine. This was essential, as the machine contains numerous components that need to be integrated into a functioning system. I virtually implemented all the desired technology into the model, which allowed me to determine the final form of the machine. This was crucial for preparing the bill of materials and ordering the necessary parts.
The next step involved designing the electrical schematic, where I defined all the required electrical parameters for the proper functioning of the embedded electronic components.
A significant amount of time was spent selecting the right components, as incorrect procurement could lead to an inferior final product and unnecessary costs.
Once the plans were completed and materials ordered, the assembly process began. First, I assembled the basic structure according to the design, then gradually added the electronic components.
In the following phase, the machine was fully assembled and wired, followed by testing, laser calibration, and troubleshooting any hidden defects. In the end, the machine functioned as intended and was ready for use.
