An experimental investigation of high-feed milling on M28

a novel metastable β–Titanium alloy

was presented. The cutting forces and material removing rate of shoulder milling and high-feed milling were compared in the typical cutting parameters of each style. Cutting forces were also compared to reveal the effect of solution and aging heat treatment on M28 in milling. The influence of cutting speed and feed per tooth on the cutting force was also analyzed. A comparison cutting experiment between M28 and TC4 shows that the cutting force of the former was almost 200%–300% times that of the latter. All the results show that M28 is imparted a strong reinforcement effect of aging treatment and the cutting force of it is much larger than that of TC4 in the same condition. Due to more proportion of the cutting force can be transmitted into the spindle axial direction

the high-feed milling shows some kind of advantage in the machining of such kind of hard-to-machine material.
