The objectives of this research are (1) to determine the design of CNC laser cutting and (2) to determine stress and deformation of the design. The type of the research is research and development (R&D). R&D is a process or steps to develop a new product or improve an existing product. R&D can also be interpreted as research which is used to produce certain products and test the effectiveness of these products. The object of the research is CNC laser cutting design. The design is accordance with design requirements and objectives (DR&O) from user. The output of the research are design concepts, finite element analysis, and detailed engineering design of the CNC laser cutting. The data collection techniques are literature study, observation, focus group discussion, and simulation. The results of the research are CNC laser cutting design with improvements from the old design. The improvements of CNC laser cutting design are (1) more accurate by using thread as a driving transmission; (2) larger work area with 650x550mm; (3) can cut metal up to 10mm by using 200W CO laser; and (4) have operation buttons and emergency button. The main materials used are ST37, Aluminum 6061, Mild Steel, and Acrylic. The main components of CNC laser cutting are the frame, case, linear actuator, control system, drive system, and CO laser. Based on the simulation, the maximum von-Mises stress of the X-Axis C-Beam on the linear actuator is 27.76MPa which located at the connection of the C-beam with the plate. The maximum deformation of the X-Axis C-Beam on the linear actuator is 0.387mm. Natural frequencies of X-Axis C-Beam on linear actuator are 119.06Hz, 128.31Hz, 133.55Hz, 219.79Hz, 359.61Hz, and 360.65Hz. © 2023 Author(s).
