There is a growing demand for improving the welding quality by reducing the machining error and improving the quality of the machined surface in the beveling for the improvement of the welding groove of the thick plate. For this purpose, it is necessary to develop an automatic beveling machine that adopts a cutting method that replaces the conventional oxygen flame cutting method. In this study, the cutting characteristics according to the machining conditions were evaluated during the face milling applied to the thick plate welding groove. We measured and evaluated cutting force for the machining conditions such as cutting depth, feed rate, chamfer angle, workpiece material, and material of the tool. We expect that this study is used as basic data for designing the stiffness of the spindle, the strength of the fixture and the power of the spindle and the feeding device when designing the automatic beveling machine.
