Effect of Increasing Spindle Speed at a Constant Chip Load on Cutting Force Behaviour of Hastelloy X

Cutting force is vital in machining nickel-based superalloys due to their excellent mechanical properties, thus creating difficulty cutting. In the current scenario of metal machining, milling processes require high spindle speed and low chip load, which result a cutting force. However, load not only but also material removal rate (MRR). It contrary ultimate high-speed (HSM) goal, improve productivity cost-effectiveness. Therefore, emergence an approach for achieving simultaneous MRR crucial. This paper presents effect increasing at constant on Hastelloy X during half-immersion up-milling down-milling. both half-immersions, simulation results experimental are good agreement. The percentage contribution feed force, normal axial resultant can be arranged descendingly from as > Moreover, have U-shaped behaviour. 24,100 rpm 0.019 mm/tooth were found achieve MRR.
