Analysis of the Effect of Cutting Motion Speed in CNC Laser Cutting on Roughness and Accuracy

The cutting speed of laser cutting is predicted to affect the roughness of its object. However, its roughness characteristics still need to be determined to consider whether it is tolerant. The aspects of cutting products are studied intensely. Specific cutting styles with different plates like Eser thick versus velocity of the cut varied, affecting the fineness of surface cutting. However, a monitor showing frequency and period explained the more significant roughness. Those are predicted to be straightforward for checking samples. Using CMM and the Surface Roughness Tester, the cutting parameter and its process can be recommended for future applications. The brief used Eser plate cutting using CNC laser cutting with thicknesses of 3 mm, 4 mm, and 5 mm with cutting speeds of 1 m/min, 1.4 m/min, and 2 m/min. The best cutting speed was 2 m/min for a plate thickness of 3 mm, with an accuracy level of 98% and 98.51%, while the lowest Ra value was 6.51 µm. The plate thickness was 4 mm, the accuracy level was 98.05% and 98.77%, and the lowest Ra value was 4.183 µm. The plate thickness was 5 mm with an accuracy level of 97.7% and 97.99% and Ra of 8.995 µm. In the laser process, the thicker an object is, the lower its accuracy. In addition, the frequency of roughness sensitivity detection impacts more than its period during a standard operation.
