Nomex honeycomb composites are used extensively in aerospace, automotive, and other industries due to their superior material properties. However, the tool wear during machining can compromise processing accuracy stability of whole process, thus studies on strengthening method urgently needed. This study presents a radial difference calculation (RDC) evaluate disc cutter quantitatively both con...

The purpose of this study is mainly to develop an information and communication technology (ICT)-based intelligent dimension inspection and tool wear compensation method for precision tuning. With the use of vibration signal processing/characteristics analysis technology combined with ICT, statistical analysis, and diagnosis algorithms, the method can be used to proceed with an on-line dimensio...

Abstract As one of the main rock-breaking tools on cutterhead shield machine, disc cutter often fails due to abnormal wear, which in turn affects tunneling efficiency order find and replace failed time, a means effectively detect wear state method diagnose failure are required.In this paper, diagnosis combining measurement ARIMA prediction is proposed, theoretical model change law under three c...

In the metal cutting process, the friction and wear behavior between the cutting tool and machined surface is the most important factor that affects the surface quality and the service life of the cutter. The irregular pore structure of porous titanium alloy has changed its mechanical properties and the processing technology. The friction and wear mechanism of the cutting tool and the machined ...

Abstract—The wear measuring and wear modelling are fundamental issues in the industrial field, mainly correlated to the economy and safety. Therefore, there is a need to study the wear measurements and wear estimation. Pin-on-disc test is the most common test which is used to study the wear behaviour. In this paper, the pin-on-disc (AEROTECH UNIDEX 11) is used for the investigation of the effec...

The reliability of disc cutters has a significant influence on the safety and working efficiency tunnel boring machines (TBMs). To investigate under different geological operational conditions, we conducted series novel rolling cutting tests intact jointed sandstone blocks using dip angles interlayers. Different normal forces rotational speeds cutterhead were also applied during experiment. A e...
