Electrical–Thermal–Mechanical Analysis of Focused Infrared Heating Process
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 7 - Trang 885-903 - 2020
Demand of infrared (IR) heating technology has been increasing in industrial heat treatment processes to replace traditional heating methods because of this technology’s high energy efficiency. However, numerical analyses of IR heating have not been sufficiently reported. This work proposes a framework for electrical–thermal–mechanical analysis of a focused IR heating process using multi-physics a......
Comprehensive Study on the Cutting Force Modeling and Machinability of High Frequency Electrical Discharge Assisted Milling Process Using a Novel Tool
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 10 Số 2 - Trang 381-408 - 2023
Remote Inspection of Internal Delamination in Wind Turbine Blades using Continuous Line Laser Scanning Thermography
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 7 - Trang 699-712 - 2020
This study proposes a continuous line laser scanning thermography (CLLST) system for remote inspection of internal delamination in wind turbine blades. The CLLST system offers the following advantages: (1) remote delamination inspection can be achieved by mechanically scanning a line laser beam and simultaneously capturing the corresponding thermal waves in nondestructive and noncontact manners; (......
Development of composite micro-patterns on polymer film using repetitive ultrasonic imprinting
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 1 - Trang 341-345 - 2014
Ultrasonic imprinting is a novel process in which micro-patterns can be replicated on thermoplastic polymer with short processing time and low energy consumption. Ultrasonic imprinting uses ultrasonic vibration energy to soften thermoplastic polymer, and to replicate micro-patterns on the softened polymer surface from a patterned horn or mold. In this study, a new patterning method based on ultras......
Inkjet−Printable Nanoporous Ag Disk Arrays Enabling Coffee−Ring Effect−Driven Analyte Enrichment Towards Practical SERS Applications
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 9 - Trang 421-429 - 2021
To make surface enhanced Raman scattering (SERS) sensors more practical, we propose nanoporous Ag disks as SERS-active plasmonic structures that can be readily inkjet-printed just before use to avoid degradation of SERS enhancement. Together with the aid of the enhanced plasmonic fields from the nanoporous Ag (confirmed by electromagnetic simulation), we utilize a coffee-ring effect to concentrate......
The influence of abrasive size on high-pressure chemical mechanical polishing of sapphire wafer
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 2 - Trang 157-162 - 2015
Demand for sapphire wafer has increased with growth of LED market. Chemical mechanical polishing (CMP) comprises a large part of wafering cost since the CMP process requires approximately 3–6 hours. For longer polishing times, the cost of consumables (COC) in CMP increases the total wafering cost; hence, considerable efforts have been made to decrease the polishing time of sapphire wafers to reduc......
The State of the Art of Finite Element Analysis in Mechanical Clinching
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 9 - Trang 1191-1214 - 2021
Clinching technology is a mechanical connection technology that is applied to connect metal or non-metal sheet materials. It is widely used in different applications, such as automobile, aircraft, household appliances and other industries. In order to reduce weight, save energy, reduce fuel consumption, reduce pollution and curb global warming, lightweight structures with clinched joint are increa......

Study on manufacturing of recycled SiC powder from solar wafering sludge and its application
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 1 - Trang 299-304 - 2014
Slurry containing SiC powder and oil is used to cut ingots with a wire in a solar cell wafering process. The slurry, which is generally recycled due to its high price, produces a residue known as sludge during the recycling process. The sludge is mainly composed of SiC, Si, and oil. This study proposed a method to remove Si and oil from sludge to obtain a high-purity SiC powder of approximately 98......
Novel Approach to Improve the Optical Performance by Machining Process Without Surface Finishing
International Journal of Precision Engineering and Manufacturing-Green Technology - Tập 8 - Trang 1381-1392 - 2021
With the increase in dimensions of optical elements in addition to ever rising demand for aspherical optics, the millimeter-scale periodic waviness that is naturally produced by machining (such as diamond turning) process in precision optical engineering has been one of the most crucial issues in the development of high surface quality optical elements. Even an extremely small waviness can affect ......
