“…This method mainly relies on the mechanical action of abrasive particles and the chemical action of oxidants in a polishing slurry to make the surface of a polished workpiece flat and smooth, which has the advantages of no surface/subsurface damage, low density of surface defects, and low cost [ 14 ]. Moreover, CMP technology has been employed for polishing the rake faces of carbide inserts, and it has been found that this method can improve the surface quality and cutting performance of an insert [ 15 , 16 ]. In addition, Qin et al [ 17 ] investigated the material removal mechanism of the chemical mechanical polishing of a carbide insert and established a material removal model for the chemical mechanical polishing of a carbide insert.…”

Typical edge defects in the edge region of a new cemented carbide insert without edge preparation include burrs, poor surface quality, micro-breakages, and irregularities along the edge. To address the problems in new cemented carbide inserts without edge preparations, a chemical–mechanical synergistic preparation (CMSP) method for the cemented carbide insert cutting edge was proposed. Firstly, the CMSP device for the insert cutting edge was constructed. Then, the polishing slurry of the CMSP for the insert cutting edge was optimized using the Taguchi method combined with a grey relation analysis and fuzzy inference. Finally, orthogonal experiments, the Taguchi method, and analysis of variance (ANOVA) were used to investigate the effect of the polishing plate’s rotational speed, swing angle, and input frequency of the controller on the edge preparation process, and the parameters were optimized. The results showed that the best parameter combination for the polishing slurry for the cemented carbide inserts was the mass concentration of the abrasive particle of 10 wt%, the mass concentration of the oxidant of 10 wt%, the mass concentration of the dispersant of 2 wt%, and the pH of 8. The CMSP process parameter combination for the linear edge had the polishing plate’s rotational speed of 90 rpm, the swing angle of 6°, and the input frequency of the controller of 5000 Hz. The optimum CMSP process parameter combination for the circular edge had the polishing plate’s rotational speed of 90 rpm, the swing angle of 6°, and the input frequency of the controller of 7000 Hz. The polishing plate’s rotational speed had the most significant impact on the edge preparation process, followed by the swing angle, and the effect of the input frequency of the controller was the smallest. This study demonstrated that CMSP is a potential way to treat the cemented carbide insert cutting edge in a tool enterprise.

“…However, great cutting force and high cutting temperature were produced in the machining of stainless steel due to its high strength and hardness at high temperature, high plasticity, high toughness and low thermal conductivity [3]. The cutting process is unstable, workhardening is serious and tools are prone to adhesive wear during machining austenitic stainless steel [4][5][6]. Therefore, austenitic stainless steel is a kind of typical difficult-to-cut material, the relative machinability is only 30%∼50% of 45 steel [7,8].…”

New TiC-TiB 2 ceramic cutting tool materials TiC-TiB 2 -Ni-Mo (TBNM8) and TiC-TiB 2 -Ni (TBN5) with high comprehensive mechanical properties were fabricated by hot pressed sintering with the optimised sintering processes. The cutting performance of TBNM8 in continuously turning austenitic stainless steel (1Cr18Ni9Ti) was experimentally investigated. With the optimal cutting parameters, the cutting performance of TBN5 and commercial tool LT55 were compared in wet and dry turning 1Cr18Ni9Ti. The failure mechanisms of the cutting tools were analysed combined with their high-temperature mechanical properties. The results showed that the tool life of TBN5 and TBNM8 was much longer in continuous dry turning 1Cr18Ni9Ti than that in wet turning, the possible reason was analysed as that the tool materials keeping high mechanical properties at elevated temperature, which led to the great improvement in machining efficiency and good characteristics of environmental friendliness because no cutting fluid was used during the cutting process.

“…It has usually been used as a surface precision polishing method for various materials such as copper, aluminum, and tungsten as well as their alloys. [2][3][4] However, the chemical activity of aluminum is stronger than zinc. The metal zinc and aluminum standard electrode potential difference (the standard electrode potential difference of Zn/Zn 2+ is −0.763 V, and the Al/Al 3+ standard electrode potential difference of −1.663 V) is large.…”

To improve the surface integrity of ZA27 alloy, a method of chemical mechanical polishing (CMP) considering the galvanic corrosion at the Zn/Al interface is proposed to treat the surface of ZA27 alloy. Firstly, the electrochemical experiment is carried out to study the influence of the pH, H2O2 concentration, and glycine concentration on corrosion potential between zinc and aluminum. Then the Taguchi method integrated with grey relation analysis and fuzzy inference are used to optimize the CMP parameters of ZA27 alloy. Finally, the prediction model of the MRR and surface roughness Ra is established using the mathematical regression analysis method. The experimental results showed that the minimum zinc-aluminum corrosion potential difference is 14 mV when the pH is 10, H2O2 concentration is 1 wt%, and glycine concentration is 0.4 wt%. The optimum CMP parameter is the polishing pressure of 34 kPa, the polishing plate's rotational speed of 70 rpm, and the abrasive particle concentration of 15 wt%. After polishing with the optimum CMP parameter, the MRR is 242 nm/min, and the surface roughness Ra is 13.91 nm. This study demonstrates that the CMP considering the galvanic corrosion at the Zn/Al interface is an effective method for treating ZA27 alloy surface.
