The objective of this study is to investigate the effects of feed and spindle speed on the flatness error on each composite using end milling cutting tools in hybrid metal matrix composites made of aluminium 6061 and 7075 reinforced with various weight fractions of SiC and Mg. Specifically, the study will evaluate the effects of these factors on the flatness error. In addition, the objective of this research is to evaluate the findings achieved in comparison to those produced by casting a specimen of Al6061 and Al7075 utilising a hybrid mode. The Constituents and the Methods involved: During the course of this experiment, a number of different spindle speeds and feed rates were utilised in order to cut slots using 10 mm high-speed steel (HSS) uncoated end mill cutting tools. All of the aluminium plates that were utilised in this experiment had a thickness of ten millimetres. This research was conducted with two groups: group 1 served as the control group, while group 2 was the experimental aluminum7075 composite. Both groups were compared to one another. The names "Groupings 1 and 2" were used to refer to both of the groups. G-Power was utilised to the extent of eighty percent for the control group, which was comprised of materials that were composites manufactured from aluminium 6061 matrix. A sample t test significance value of p=0.000 (both 2-tailed) is considered to be statistically significant. This result was achieved, which is lower than the threshold of p<0.05, suggesting that there is a statistically significant difference between the two groups. The findings of the research suggest that the values for evaluating the flatness error of the machined slot at various spindle speeds for Al6061 and Al 7075 metal matrix composites are 0.003 mm and 0.015 mm, respectively. These values were determined by the metal matrix composites. On the other hand, further information concerning the characteristics of the materials was acquired. Within the parameters of this investigation, a comparison is made between the control group and the experimental group with regard to the flatness error values. Based on the findings of this comparison, it can be concluded that the utilisation of Al7075 HMMC leads to a 41 percent improvement in outcomes. This is performed while taking into consideration the characteristics of the material. [ABSTRACT FROM AUTHOR] |
