While the combination of virtual reality (VR), industrial internet of things (IIoT) and digital twin (DT) can promote the integration of the physical world (real) and the digital world (virtual), one of the most important challenges that companies face is the choice of architecture. This study intends to utilize VR, IIoT, DT advantages and to reduc...

This study aims to conduct abnormality detection by applying machine learning algorithms when drilling a carbon fiber reinforced plastic laminate. In-process signals including current, thrust force, and vibration were captured during the dry drilling experiments using a 6 mm physical vapor deposit diamond-coated drill at the consistent spindle spee...

A gear is used not only for power transmission but also in precision positioning. A conventional and general gear has only one degree of freedom motion. Therefore, the case of its use is limited. In this paper, we propose and manufacture an innovative spherical gear. The proposed spherical gear has a multiple degrees of freedom motion. Compared wit...

Camera calibration is essential for calculating camera parameters, and the parameters should be constant whenever the position tracker needs to be recalibrated. Manual camera calibration obtains a checkerboard image by tilting or positioning the checkerboard by hand. However, it makes difficult to obtain the same checkerboard images in every calibr...

In this study, sustained and pH-responsive delivery of drugs were conducted using sealed microcontainers (MCs). The MCs were fabricated using a polydimethylsiloxane (PDMS) stencil. The polymer solution was filled into holes of the stencil space; then, the organic solvent was evaporated to obtain MCs. Poly(lactic-co-glycolic acid) (PLGA) was used as...

For the ultra-precision turning machine, the spindle system is a core component and plays a decisive role in precise machining. The unbalancing state in the spindle can degrade the quality of the machining surface. Therefore, the spindle system must be exceptionally well balanced before processing. In this paper, we proposed a high accuracy spindle...

The near-net-shaped blade is adopted in the aero engine as it’s material-saving and efficient. However, the leading edge shape’s curvature is sharply changed in its machining process and the deformation trend of each cross section has slight differences. Using the traditional machining method is exhausting and time-consuming. Furthermore, it brings...

The joints of four aluminum alloy (7075, 5754, 6061, 1060) sheets were prepared using the clinching process with different die assemblies, and the forming and mechanical properties of the produced joints were evaluated using different testing procedures. The neck thickness, undercut values, bottom thickness, and joint dimensions of the joints were ...

This study investigates the tool-wear-reduction mechanism of graphite-powder mixed kerosene (GPMK) in micro electric-discharge machining (EDM). RC discharge circuits produce small, short discharge pulses and are therefore widely used in micro-EDM, rather than transistor circuits. In this case, given that an anode has higher energy proportion than a...
