Abstract—This study aims to provide the value of the cutting force coefficient on the rough 5 axis milling machining process using flat end 4 flute tools on the peek material. The cutting force coefficient is an experimental machining parameter obtained from modeling. The machining process with several spindle rotational speeds produces a morphology chip, which is then used as modeling information to form a cutting force coefficient graph from an experimental stage. Using 5 variations of spindle speed and constant depth of cut, the results obtained for the thickness of the chip resulted in differences in the coefficient of cutting force. At the highest spindle speed, the chip thickness resulting from the machining process is reduced compared to the lowest spindle rotation. Consequently, the value of the cutting force coefficient will increase compared to other lower spindle speeds.
