“…Single-objective optimization (SOO) is a powerful method used to achieve the "best" solution by maximizing or minimizing a single objective [20]. Depending on the objective of the experiment, the individual response characteristics are optimized based on the signal-to-noise (S/N) ratios using the following technique [21]:…”

The optimization of machining processes is a deciding factor when increasing productivity and ensuring product quality. The response characteristics, such as surface roughness, material removal rate, tool wear, and cutting time, of the finish turning process have been simultaneously optimized. We used the Taguchi-based design of experiments L9(34) in this study to test and find the best values for process parameters like cutting speed, feed rate, depth of cut, and nose radius. The Taguchi-based multi-objective grey relational approach (GRA) method was used to address the turning problem of Inconel 718 alloy to increase productivity, i.e., by simultaneously minimizing surface roughness, tool wear, and machining time. GRA and the S/N ratio derived from the Taguchi approach were utilized to combine many response characteristics into a single response. The grey relational grade (GRG) produces results such as estimations of the optimal level of input parameters and their proportional significance to specific quality characteristics. By employing ANOVA, the significance of parameters with respect to individual responsibility and the overall quality characteristics of the cutting process were ascertained. The single-objective optimization yielded the following results: minimal surface roughness of 0.167 µm, tool wear of 44.65 µm, minimum cutting time of 19.72 s, and maximum material speed of 4550 mm3/min. While simultaneously optimizing the Inconel 718 superalloy at a cutting speed of 100 m/min, depth of cut of 0.4 mm, feed rate of 0.051 mm/rev, and tool nose radius of 0.4 mm, the results of the multi-objective optimization showed that all investigated response characteristics reached their optimal values (minimum/maximum). To validate the results, confirmatory experiments with the most favorable outcomes were conducted and yielded a high degree of concurrence.

“…Increasing the wear resistance of cutting tools is a very urgent problem, which is solved in various ways: by creating new tool materials with improved physical, mechanical and cutting properties [1][2][3][4], by modifying the working edges of the tool with wear-resistant coatings [5][6][7][8], by assessment of the thermal load of the tool [23] and by selecting optimal technological operating modes for the tool [9][10][11]. One of the main factors that contribute to the intensification of wear processes of tool cutting materials is significant vibrations in the cutting system.…”

This article is devoted to determining the rational range of cutting speeds during longitudinal finish turning of heat-resistant steel 20MnMoNi5-5 based on a set of tribological and vibration parameters of the cutting process. Turning workpieces with diameters D=120 mm made of 20MnMoNi5-5 steel with T15K6 carbide plates without cooling at finishing feeds and allowance values at cutting speeds of 100-220 m/min was carried out and studied. It was experimentally established that the local minimum for vibration energy was located within the speed range of 190-220 m/min. According to the results of tool life tests in this speed range, the wear rate of the cutting inserts was also minimized and the operating time of the tool was increased, making it possible to ensure the required surface roughness Ra≤1.6 μm.
