“…As cutting progresses, the periodic removal of adhered material from rising shear stresses can result in attrition or pull out of the carbide particles leading to chipping, notching or fracture of the tool edge [5,160]. In addition, tools exposed to increasing stress and temperature are also prone to suffer from plastic deformation as observed in turning and milling processes [86,87,214].…”

“…However, the technology is widely used as well for high performance cutting of various hard to machine aerospace alloys, such as titanium and nickel based alloys. The main objectives are to increase tool life while decreasing cutting forces and improving surface finish and form accuracy [29,86]. Even though there is still a huge need for research in the field of VAM, it is used in industry for various cutting processes [29].…”

“…In addition, delamination of protective coatings was clearly distinguished in his research. Various researchers [12][13][14] have previously reported when machining difficult-to-cut materials, such as titanium alloys. It was found that the residual tensile stress in the coating surface significantly affects the incipient crack formation and extension [13] and the thermal effects inducing degradation in thermal conductivity of the tool-coating combination were considered to be the main reason of coating failure [14].…”

Coated carbide tools are widely used in machining titanium alloys due to their excellent wear resistance, high strength, and hardness even at elevated temperature. The paper gives a special attention to the failure mechanisms of coated carbide cutting tools during high-speed intermittent cutting process. The effects of serrated chip formation on the instantaneous cutting forces, transient temperature, and thermal stress distributions on the cutting tool were investigated based on finite element method (FEM). The results show that the cutting tools undergo combined thermomechanical and high/low cycle fatigue loading during intermittent cutting process. Micro-crack propagation and coating delamination were observed on the cutting edge and rake face. Flank wear and brittle fractures on the cutting edge caused by crack propagation were identified as the main failure mode of coated carbide tools in intermittent cutting process. Intense tensile thermal stress on the cutting tool edge was found to be produced by differential cooling rates in the idle periods. The rapid alteration of stresses was believed to be the direct cause of crack propagation on the cutting edge.

A long, quasi-homogeneous cold plasma jet was generated through a homemade cold plasma jet generating device. Friction-wear test and assisted cutting of Ti6Al4V were studied under air, nitrogen, and nitrogen cold plasma jet (NPJ) atmospheres. The friction coefficient under nitrogen jet was small, and the wear appearance was smooth at lowspeed friction. At high-speed friction, the friction coefficient under NPJ was the smallest, which declined by 70 % compared with that under air atmosphere. The scratches and adhesive traces on the friction surface were the lightest as well. The lubrication and cooling effects were not evident under low-speed cutting, whereas the NPJ enabled the radial force Fy and the average flank wear width VB to decrease by nearly 40-47 % respectively under high-speed cutting compared with the ones under air atmosphere. Results show that the NPJ assisted cutting has little influence on the surface roughness, residual stress, and work hardening of workpieces, while the machinability of Ti6Al4V can be effectively improved.
