The hard milling is machining of the hardened materials with the hardness range from 40 HRC to 70 HRC. This is an efficient solution that can be used to replace the grinding operation in the mold and die manufacturing industry dynamics and the cutting conditions must be considered and chosen properly for hard milling. This paper shows the cutting conditions for hard milling process are chosen through the stability lobe diagram of a machine tool. Firstly, the determination of the average cutting force coefficients for the tool-material pairing is carried out through slot milling experiments. Secondly, the measurement of frequency response functions for a milling machine tool is performed based on the hammer tests. Finally, the development of the stability lobe diagram is conducted by the use of the Cutpro software. The result reveals that the spindle speed and the axial depth of the cut in a stable cutting region were considered and selected for the hard milling.
