In theoretically traditional practice, the cutting force calculation/prediction based on the cutting force coefficients (CFCs) will not be affected by the properties of the machine tool such as the structural dynamics and the Frequency Response Function (FRF), etc. It means the CFCs are related only to the paired cutting tool and workpiece, but not the machine. However, it seems to be not the same in practice. This paper proposes an alternative method by conducting the cutting test experiment on the other machines that have enough working space for a dynamometer to be installed for the cutting test, and then applying it to a small working space machine. A series of experiments had been designed for cutting test and tapping test to verify the proposed method. This paper then focused on the exploration of varieties that influence the cutting forces. Finally, a new stable machining method has been successfully developed and verified with a case study by using a real seven-axis mill-turn machine tool (MTM) different from the machine tools used for the cutting test.ABSTRACT
