“…Thermal phenomena accompanying the grinding process significantly impact the quality of the ground surfaces [12]. High grinding temperatures cause defects in the surface layer of the ground part (e.g., burns, cracks) [13], which reduces the part's quality [14], and therefore the temperature factor becomes one of the main factors of the grinding process [15].…”

One of the features of sintered materials is porosity. Depending on the application, this can be both a disadvantage and an advantage. The porosity geometry affects the propagation of heat during the grinding of the sintered material. An experimental study of the temperature in the cutting zone during the grinding of sintered porous materials was carried out. The relationship between the contact temperature in the cutting zone, the parameters of the cutting modes during grinding, and the porosity of the part is revealed. It was found that the use of process coolants is not always possible due to the presence of pores in the material. It is proved that the cutting temperature of porous materials is higher due to the deteriorated heat dissipation properties, but the cutting temperature does not affect the degree of compaction of the surface layers of the powder material. An adequate mathematical model is obtained, which describes the change of cutting temperature depending on the material's cutting depth, grinding speed, and porosity.

“…Tool-wear-monitoring methods include direct measurement methods and indirect measurement methods. AI technology is actively utilized in various methods in the manufacturing industry [ 9 , 10 , 11 ], and various methods using AI technology in direct and indirect measurement methods are being studied for tool wear monitoring [ 12 ]. The direct measurement method is a method of directly measuring the tool wear area using an optical microscope or vision sensor.…”

A novel method for tool wear estimation in milling using infrared (IR) laser vision and a deep-learning algorithm is proposed and demonstrated. The measurement device employs an IR line laser to irradiate the tool focal point at angles of −7.5°, 0.0°, and +7.5° to the vertical plane, and three cameras are placed at 45° intervals around the tool to collect the reflected IR light at different locations. For the processing materials and methods, a dry processing method was applied to a 100 mm × 100 mm × 40 mm SDK-11 workpiece through end milling and downward cutting using a TH308 insert. This device uses the diffused light reflected off the surface of a rotating tool roughened by flank wear, and a polarization filter is considered. As the measured tool wear images exhibit a low dynamic range of exposure, high dynamic range (HDR) images are obtained using an exposure fusion method. Finally, tool wear is estimated from the images using a multi-view convolutional neural network. As shown in the results of the estimated tool wear, a mean absolute error (MAE) of prediction error calculated was to be 9.5~35.21 μm. The proposed method can improve machining efficiency by reducing the downtime for tool wear measurement and by increasing tool life utilization.

“…Dissimilar welding of thermoplastic is one of the best solutions in engineering due to reduction in weight [30]. In general, FRW of dissimilar polymeric materials is a difficult task because the material flow during FRW is the factor most affecting the welding mechanism required for manufacturing qualified welded parts.…”

Friction welding (FRW) is a promising method for joining cylindrical components of dissimilar and similar polymers or metals. In particular, FRW is capable of generating defect-free welds. Fused deposition modeling (FDM) has been widely employed in the automotive industry, ranging from lightweight tools, testing models, and functional parts. Conventionally, dissimilar parts fabricated by FDM are joined by glue. However, distinct disadvantages of this approach include both low joining strength and low joining efficiency. Hitherto, little has been reported on the characterizations of weld strength of FRW of dissimilar parts fabricated by FDM. In addition, FRW of dissimilar polymeric materials is a difficult task because different polymers have different physical, rheological, and mechanical properties. In this study, the effects of welding revolution on the weld strength of friction welding dissimilar parts fabricated by FDM are investigated experimentally. It was found that the average flexural strength of dissimilar polymer rods fabricated by FRW is about 1.52 times that of dissimilar polymer rods fabricated by gluing. The highest flexure strength can be obtained by FRW using polylactic acid (PLA) and PC (polycarbonate) rods. The average impact strength of dissimilar polymer rods fabricated by FRW is about 1.04 times that of dissimilar polymer rods joined by gluing. The highest impact strength can be obtained by FRW using PLA to PLA rods.
