Speech Title: Advanced Manufacturing Cloud of Things (Industry 4.0 + AVM = Industry 4.1) 

Abstract: Virtual Metrology (VM) is a method to conjecture manufacturing quality of a process tool based on data sensed from the process tool and without physical metrology operations. In other words, VM can convert sampling inspection with metrology delay into real-time and on-line total inspection. This talk will first introduce the theories and functions of the Automatic Virtual Metrology (AVM) system and then demonstrate how to apply AVM to high-tech (semiconductor, TFT-LCD, etc.) and traditional machine-tool (automobile wheel machining, airplane engine casing, etc.) industries. The current Industry 4.0 platform can only keep the faith of achieving the nearly Zero-Defects state without realizing this goal. In other words, Industry 4.0 only emphasizes "Enhancing Productivity" but not "Improving Quality". The key reason for this inability is the lack of an affordable online and real-time total inspection system. The Zero-Defects state can be achieved by adopting the AVM system due to its capability of providing all products total inspection data. As the AVM system is integrated with the Industry 4.0 platform, the goal of Zero-Defects can be accomplished, which is defined as "Industry 4.1." This talk then focuses on how to utilize Internet of Things (IoT), Big Data Analysis, Cloud Manufacturing (CM), and Cyber Physical Systems (CPS) along with the AVM technology to develop an Advanced Manufacturing Cloud of Things (AMCoT) that construct a smart manufacturing platform for achieving the goals of Industry 4.1.

Biography: Soon after Fan-Tien Cheng graduated from the department of Electrical Engineering of National Cheng Kung University (NCKU) in 1976, he got in the Chung Shan Institute of Science and Technology (CSIST), serving as Research Assistant at the most basic level and then got promoted to Senior Scientist in 19 years. Then he went back to NCKU to start his teaching career and devoted the knowledge and practices he had learned in CSIST to the research domains of manufacturing automation and e-Manufacturing for industries such as semiconductor, TFT-LCD, solar cell, machine tool, and aerospace to help achieve the goals of enhancing the industry competitiveness by successfully improving manufacturing processes and lowering production cost. 
Professor Cheng’s research achievements are significant both academically and industrially in the domains of e-Manufacturing, Smart Manufacturing, and Industry 4.1. Among those, he has been taking the lead especially on the academic and practical applications of VM technologies. So far, he has more than 25 VM-related journal papers, dozens of VM invention patents both domestically and internationally, and 35 AVM-related technology transfers to high-tech industries like semiconductor (TSMC, UMC, ASE), TFT-LCD (CMI, AUO), solar cell (Motech) and traditional industries such as aerospace (AIDC) and machine tool (FEMCO) as well as foundations/associations like ITRI and MIRDC. In one word, he has exceptional contributions in both the academy and industries.

Speech Title: Closed Form Solutions of Interfacial Shearing and Peeling Stresses at Layered Structures in Electronic Packaging 

Abstract: The study of thermal mismatch induced interfacial stresses at layered structures and their role in structural and functional failure is one pertinent topic to electronic packaging and photonic applications. Therefore, an understanding of the nature of the interfacial stresses under different temperature conditions is necessary in order to minimize or eliminate the risk of mechanical failure. An accurate assessment of interfacial thermal stresses plays an important role in the design and reliability studies of microelectronic devices. In the microelectronic industry, from a practical point of view, there is a need for simple and powerful analytical models to determine interfacial stresses in layered structures quickly and accurately.

The present lecture will briefly review the previous work on the determination of interfacial thermal stresses. In the present work, the case of uniform temperature model of two layered structure has been extended to account for differential uniform temperatures as well as linear temperature gradient in the layers. The expression of shear stress compliance is defined to avoid contradictions by the earlier researchers. The influence of bond material and geometric properties on interfacial stresses is also considered in a simple way.

Finally, a simple and improved solution for tri layered structure subjected to uniform and differential uniform temperature in the layers is proposed by removing the short comings of the earlier model. The condition for bow free assembly is also discussed.

Speech title: Application of Vegetable-based Lubricant as a Sustainable Metalworking Fluid for Machining Process

Abstract: Continuous implementation of lubricants from renewable sources such as animal fats, vegetable oils and biolubricants as metalworking fluids in machining applications was contributed by the increase awareness from human health deficiency and bad environmental impacts as well as on sustainable development for future manufacturing activities. Renewable lubricants from vegetable oils are very attractive as alternative lubricant source which pose relevant properties such as highly biodegradable, non-toxic, have good lubricating properties, are made from renewable sources and bear low production costs. Vegetable-based metalworking fluids from palm oil and jatropha oil are desirable as the alternative to mineral oil that possessed negative effect to human and environment. The assessment of its performance was conducted tribological and machinability aspects. Both palm and jatropha oils were chemically modified through various processes and added with an additive, such as ionic liquid and hexagonal boron nitride. The tribological properties of the palm and jatropha oils were further improved in terms of its friction and wear performances by adding the additives. The machining performances of these newly invented vegetable-based MWFs were evaluated in terms of cutting forces, cutting temperature, surface roughness and tool life during turning of AISI 1045 medium carbon steel using uncoated cermet inserts under MQL technique. The thin lubrication film formed by the vegetable-based oils was able to withstand the friction at the tool-workpiece interface, resulted in low cutting force, low cutting temperature, lower surface roughness value and prolonged tool life. This phenomenon was attributed to the formation of long and branched carbon chains in palm and jatropha oils molecule which increased the absorption film ability. From the results of the tribological and machining performances evaluations, the newly developed vegetable-based MWFs were significantly surpassed currently used synthetic ester thus provides new opportunities for minimum quantity lubrication-based oil.
