Abstract: Cutting process modeling is still a significant challenge due to the severe plastic deformation of the workpiece and intense friction between the workpiece and tool. Nowadays, a novel experimental approach based on digital ...

Abstract: Hard turning is becoming increasingly considered by industry as a potential substitute for grinding. However, it is greatly hurdled by surface integrity problems such as tensile residual stress and white layer, which are ...

Abstract: Abstract. Machining of silicon carbide particle-reinforced aluminum matrix (SiCp/Al) composites is challenging due to the complex interactions between the cutting tool and silicon carbide (SiC) particles, which critically ...

Abstract: Abstract. SiCp particle-reinforced Al (SiCp/Al) metal matrix composites offer excellent mechanical properties but are prone to surface defects during machining due to microstructure non-uniformity. Accurate surface roughness ...

Abstract: Chatter is an undesirable dynamic phenomenon in machining processes, which causes cutting disturbance, overcut, quick tool wear, etc., and thus seriously impairs workpiece quality. To mitigate chatter, traditional methods ...

Abstract: The real-time monitoring of visibility for expressway traffic safety cannot be widely achieved due to the high cost of the traditional method. This paper proposes a novel method to monitor expressway visibility using two ...

Abstract: In five-axis milling process, the tool path generated by a commercial software seldom takes the dynamics of the machining process into account. The neglect of process dynamics may lead to milling chatter, which causes ...

Abstract: Residual stress, characteristic of surface integrity, is a great issue in cutting process for its significant effects on fatigue life and dimension stability of the machined parts. From a practical viewpoint, residual ...

Abstract: Machining process dynamics can be described by state-space delayed differential equations (DDEs). To numerically predict the process stability, diverse piecewise polynomial interpolation is often utilized to discretize the ...

Abstract: Cutting stress field in machining process plays a significant role in the understanding of cutting mechanics and prediction of surface integrity, tool wear, and failure. It is in great need to get accurate and reliable ...
