“…On the other side, feed rate is decreased with respect to decreasing the chip load. Further, as reported in [7][8][9], cutting force is found to decrease with an increase in spindle speed, while as chip load decreases the cutting force will also decrease. Therefore, increasing spindle speed while decreasing chip load will significantly decrease the cutting force during metal cutting.…”

Research on cutting force revealed that the cutting force decreases as cutting speed increases, which is in line with Salomon’s Theory. However, the fundamental behaviour was never clearly explained because most studies had focused on increasing the cutting speed by increasing spindle speed without retaining the rate of chip load. On that note, the effect of increasing spindle speed while chip load is constant on the cutting force of Hastelloy X is presented in this paper. Third Wave AdvantEdge software was applied and half-immersion up-milling simulations were conducted in dry condition. Result showed that the resultant force was primarily affected by the axial force, followed by normal force and feed force. Trend-lines indicated that the behaviour of cutting force components and resultant force was quadratic. Desirability Function Analysis (DFA) results revealed that the optimum combination of chip load and spindle speed led to lowest cutting force components and resultant force was at 0.013 mm/tooth and 24,100 RPM. Furthermore, the optimum cutting conditions that led to the lowest cutting force components and resultant force at chip loads of 0.016 mm/tooth and 0.019 mm/tooth was 24,100 RPM also. Therefore, increasing Material Removal Rate (MRR) while minimizing cutting force components and resultant force can be achieved by increasing the amount of chip load at spindle speed of 24,100 RPM.

“…Given that there is a direct relationship between power and cutting force in milling and that most researchers emphasize the effects of these milling modes on cutting force, we can say that our results are consistent with previous research. The studies of [20,22,34,35], show that the cutting force in down milling is greater than that in up milling. Based on the consistency between power and cutting effort, we can say that our work is in good agreement with previous work.…”

Increasing the quality of a machined product and minimizing energy consumption is a primary objective for all industries, given their significant impact on manufacturing costs and the environment. The choice of the machining process and the optimal cutting parameters to meet this requirement is the objective of this experimental study, which deals with the effects of the cutting parameters and the machining process on the energy consumption and surface condition during the milling of AISI 304L austenitic steel. This article presents a multi-objective optimization method based on the response surface methodology and Grey's weighted relational analysis. Based on this approach, the down milling cutting parameters indicate that the cutting speed is the most influential parameter on energy consumption (62.71%), while the feed rate is the most influential factor in roughness (47.20%). For up milling, the cutting speed is the most important factor influencing surface roughness (29.07%) and also energy consumption (64.09%).It has also been found that the cutting power can be reduced by 39% for down milling and 16% for up milling compared to the maximum value. On the other hand, the quality of the machined surface can be improved by 58.5% for down milling and by 60% for up milling.

“…It is well established that the cutting forces and thermal gradients generated by the up-milling and down-milling modes during the contact tool-material are not identical [2,3]. Consequently, the machined surface integrity (including surface roughness, micro-structural changes, residual stresses and sometimes damaging defects) is certainly different [4][5][6] as well as the tool wear rate [7][8][9] and also the dynamic stability of milling process [10].…”

The experimental investigations showed an important difference between integrity of both milled surfaces. The down-milled surface is lowly work-hardened and well finished (lower roughness), but subjected to tensile residual stresses and severely damaged by folds of metal and short micro-cracks. The up-milled surface is highly work-hardened and subjected to compressive residual stresses, but poorly finished (higher roughness) and damaged by a density of micro-cavities due to carbide extraction. The results of 3-point bending fatigue tests revealed that the fatigue limit at 2 × 10 6 cycles of the up-milled state is largely higher of about 26% in comparison with the down-milled state. The effects of surface integrity induced by each milling mode on fatigue strength were evaluated using a HCF behaviour predictive approach based on Dang Van's multiaxial criterion. The predictive results estimated that the pre-existing micro-cracks play a dominant role in the fatigue strength degradation of the down-milled surface while the other surface effects seem to be lower. On the contrary, the fatigue strength of the up-milled surface is less affected by the pre-existing micro-cavities. The detrimental roughness effect (stress concentration effect) is significantly reduced by the beneficial effects of superficial hardening and compressive residual stresses. So, this study revealed that up-milling is the more appropriate mode for a better surface integrity towards fatigue strength of X160CrMoV12 steel than the down-milling mode.
