“…As observed at the end of the works, gradual notch wear and Built-Up-Edge (BUE) were encountered on the tool surface while the feed rate greatly influenced surface roughness. The findings were in agreement with the work by Mohd Ali [14], where the primary factor affecting the surface roughness value is feed rate, followed by cutting speed and depth of cut.…”

Inconel 718 with exceptional characteristics is well known as a difficult-to-cut material especially during high-speed machining process. High cutting temperature further damaged the tool which results in low tool life. To overcome this matter, optimization on cutting parameters needed to be conducted in order to achieve longer tool life and desired cutting finish. Sets of optimized parameters consists of different cutting speed and feed rate were listed out through Research Surface Method (RSM) software which the effects and the output values were observed through high-speed end milling work on a 100 x 100 x 150 mm Inconel 718 block. The lowest cutting force and surface roughness at 776.04 N and 0.195 µm were recorded at the lowest parameter combination, while the highest results of 1,322.89 N and 0.478 µm were obtained from the highest parameter combination. Higher cutting parameter further deteriorate the cutting tool due to high heat and drastic reduction in tool life was observed, from 32 minutes of cutting process to only 2 minutes and 40 seconds. The results were further investigated through optimization work and cutting speed is the dominant factor that affected the results. The final model suggested that by using uncoated carbide tools, the lowest cutting speed and feed rate of 50 m/min and 0.05 mm/tooth can be implemented to obtain the desired cutting responses.

“…An analysis of the effect of feed rate and cutting speed on the surface roughness was analytically and experimentally investigated by Mohd Ali [6]. The conclusion that was found from the research was that the feed rate was the predominant parameter which determines the condition of the surface roughness.…”

This research work considered the high speed milling operation of Inconel 718 using a 4 flute solid carbide end mill tool without the use of coolant. Inconel 718 is a Nickel based Heat Resistance Super Alloy (HRSA) that is vastly used in the aerospace industries due to its excellent corrosion resistance and good mechanical properties. However, Inconel 718 is considered as a difficult-to-cut super alloy, which poses several problems when machining the material. The aim of this work is to investigate the effect and the influence of cutting parameters (feed rate, spindle speed, and depth of cut) on the quality of the machined surface as well as to evaluate the tool wear after machining. This evaluation of the surface roughness was done using a CNC milling machine at various parameters range for the values of feed rate (50-150 mm/min), spindle speed (2000-4000 RPM), and depth of cut (0.05-0.1 mm). The experiment was designed using Response Surface Analysis Method with Central Composite Design (CCD) to optimize the experimentation. The resulting tool wear and surface roughness after high speed machining were then analysed using ANOVA to determine the cutting parameters which is most affecting the surface roughness.

Al/SiCp-Gr hybrid aluminum matrix composites are used for high performance"ceramic" brake discs as it is able to withstand extreme temperatures. The addition of solid lubricant particles such as graphite along with SiCp as hybrid reinforcements effectively improves the tribological properties of the composites. There is still a need for the detailed, economic and systematic study of their machining characteristics in engineering applications of these composites. We report the influence of cutting parameters and effect of graphite rate on cutting force and surface roughness in drilling Al/20%SiC/5%Gr, Al/20%SiC/7.5%Gr and Al/20%SiC/10%Gr hybrid composites fabricated by vortex method. The drilling tests were conducted with diamond like carbon (DLC) coated cutting tools. Taguchi's L9 orthogonal array, S/N ratio and analysis of variance (ANOVA) were used for finding the optimal process parameters for cutting force and surface roughness, Ra. Linear regression model was developed for surface roughness and cutting force to check the model adequacy. Statistical analysis results show that the rate of graphite and feed was found to be significant parameters for surface roughness (Ra) and cutting force. Spindle speed has the insignificant effect on cutting force by the ANOVA The predicted values from the developed model and experimental values were found to be very similar in this study.

Reinforcement of aluminium alloys with solid lubricants, hard ceramic particles, short fibres and whiskers effectively improves the mechanical, physical and tribological properties of the composites. Hybrid aluminium matrix composites are used for high performance "ceramic" brake discs since they are able to resist extreme temperatures [1] to [5].
