Fibre-reinforced polymer composites have begun to replace the conventional monolithic materials in the recent years as a result of better specific strength and enhanced characteristics. The present work has put forward an attempt to study the dry-sliding wear behaviour of CFRP composites followed by implementation of Taguchi-GRA combinatorial approach for the two output responses namely, wear and frictional force. Load (L), sliding distance (D), sliding velocity (S), and percent of fibre reinforcement (R) are considered as input conditions and the experiments were planned using design of experiments. In addition, Principal Component Analysis (PCA) has taken into consideration for the weights calculation in GRA. An elaborate study on the implementation these methodologies on the combined behaviour of wear and frictional force has been presented. Furthermore, ANOVA data is analysed, it appears that both the load (L) and the percent reinforcement (R) has greater effect towards the wear behaviour. A detailed discussion on wear mechanism has also been presented with a support of SEM morphology.

“…There is a constant need to decrease the tooling cost in order to produce things more affordably, particularly when executing machining processes. One of these needs is to lengthen the lifespan of the cutting tool by choosing the most suitable cutting parameters, resulting in reduced surface roughness and cutting forces [1][2][3]. In this approach, many experimental designs and methodologies, such as Taguchi and Response Surface methods, are carried out to select optimum experimental parameters, saving time and cost.…”

In this study, the ideal experimental design planning for the machining process was investigated. Two experimental designs were created by differentiating the parameter levels considered in the drilling process of stainless-steel. Close and far-level designs were obtained by creating 20% and 40% differences between the parameter levels. In the experimental system prepared according to the Taguchi method, surface roughness and cutting forces were measured as the output parameters. The results were analyzed statistically by optimization, analysis of variance and correlation analysis, and visually by chip morphology examination. According to the findings, it was determined that a 20% difference between the parameter levels was more appropriate in terms of experimental system stability, statistical data significance, and chip morphology.

“…They claim that the higher the cutting speed and the depth of cut, the higher the process temperature; this may lead to thermal cracking, plastic deformation and oxidation. Sahoo et al [15] optimize the drilling process in terms of the tool wear, spindle speed (215, 315 and 455 rpm) and feed per revolution (0.106, 0.213, and 0.316 mm/rev) to obtain the lowest surface roughness. They found that at 455 rpm and 0.106 mm/rev, the surface roughness was the lowest.…”

This article discusses experimental results concerning the quality of through holes drilled in Inconel 718. The tests involved hole cutting under 27 different conditions using different values of the feed per revolution and spindle speed, and different types of kinematic system. The drilling was performed on a CTX Alpha 500 universal turning center using tools with internal coolant supply. Three kinematic systems were considered for hole cutting. The first, based on the driven tool holder, had a stationary workpiece and a rotating and linearly fed tool. In the second, where drilling was based on the spindle rotations, the workpiece rotated while the tool moved along a straight line. In the third system, the workpiece and the tool rotated in opposite directions; the tool also performed a linear motion. The study aimed to assess the quality of holes on the basis of the following output parameters: the hole diameter, cylindricity and straightness errors, and the surface texture. A multifactorial statistical analysis was used to determine how the hole quality was dependent on the process parameters and the type of drilling kinematics. The findings confirm that the kinematic system, as well as the feed per revolution, are the key factors affecting the quality of holes drilled in Inconel 718. The analysis of the hole drilling process for Inconel 718, performed using a CNC turning center, shows that the third kinematic system was the best option as all the four parameters describing the hole quality had the lowest values. The best results were obtained in the 6th (n = 637 rpm, fn = 0.075 mm/rev, KIN III) and 8th experiments (n = 955 rpm, fn = 0.075 mm/rev, KIN II), because the parameters were then the lowest, with the scatter of results being up to 30%.
