제조환경이 더욱 복잡해짐에 따라 전통적인 시뮬레이션만으로는 실시간 현장 결과를 평가하는 데 많은 어려움을 겪고 있다. 이를 극복하기 위한 대안으로 Digital Twin개념이 활발히 논의되고 있지만, 제품설계 단계에 국한되어 연구가 진행되고 있는 실정이다. 본 연구는 Digital Twin개념이 생산 공정 프로세스에 적용되기 위한 Digital Twin 기반 제조환경 프레임워크를 제시하였다. 구성요소는 실제 생산환경인 물리적 시스템과 데이터베이스, 그리고 가상 시스템인 트윈 모델을 제안하였다. 본 연구에서는 Arena 소프트웨어와 엑셀 VBA를 활용하여 컨베이어 시스템을 대상으로 간단한 Digital Twin 기반 제조시스템을 모의실험하였다. 실험결과 트윈 모델이 실제 물리적 시스템의 실시간 데이터를 전송받아 동일한 시간단위로 작동됨을 확인하였고, 엑셀 VBA에서 축적된 실시간 데이터와 학습 데이터를 기반으로 조정된 파라미터를 생성하고 있음을 확인하였다. 또한, 간단한 모의실험을 통해 Digital Twin 모델 구동 방법을 제안하였으며, Digital Twin 모델의 구현 가능성을 보여주었다.

Recent manufacturing system requires development on new production technology to enable prompt manufacturing of diverse products. Most of the researchers have been working on micro-factory. Especially, focus on manufacturing of micro parts. Present manufacturing system consumes excessive resources in the form of energy and space to manufacture the micro parts. In this study, the micro lens module assembly system was modeled, analyzed with MST(Micro System Technology) Application Module and simulated through UML Language (Unified Modeling Language) with object-oriented logical model analysis method. Digital model of micro-factory was modeled, to execute the new paradigm of digitalization on products, resources and processes of micro-factory.

Existing manufacturing system has consumed too much energy, space and resource in micro parts manufacturing. To improve this, micro factory system is suggested. But it is difficult to get the high reliability in the assembly, production and inspection of the minute parts because the construction of the micro factory has been started just before. In this study, we will build the digital manufacturing simulation on the micro factory's process and verify the production and assembly process using this simulation.

Nowadays, the increasing global competition forces automobile manufacturer to increase quality and to reduce the cost and time for manufacturing planning. To solve these problems, automobile manufacturers try to apply digital manufacturing technologies. In this paper, a concept of method for planning the digital assembly system is proposed. Based on the requirements of assembly tasks obtained through product analysis, the function and sequence modeling for assembly process is executed using the IDEF0 and UML model. For implementation of digital assembly system, the selected components are modeled by using 3D CAD tools. According to the system configuration strategy, lots of the alternative solutions for the assembly system are generated. Finally, the optimal assembly system is chosen by the evaluation of the alternative solutions with TOPSIS(Technique for Order Preference by Similarity to Ideal Solution) method. According to proposed procedure, digital laser welding system is implemented in DELMIA.

Digital Virtual Manufacturing is a technology to facilitate effective product developments and agile productions by digital model representing the physical and logical schema and the behavior of real manufacturing system, and it includes product, resources, processes and plant. For successful applications of this technology, a digital virtual factory as a well-designed and integrated environment is essential. In this research, we constructed a sophisticated digital virtual factory of a Korean automotive company's press shop. For efficient constructions of a digital virtual factory useful to kinematic simulations and visualizations, we analyzed entire business process and detailed activities of press engineering. Also, we evaluated geometries, structures, characteristics and motions of a plant and machines in press shop. The geometric model and related data of a virtual press shop are built and managed by a modeling standard defined in this paper. The virtual manufacturing simulation of press machines is conducted to evaluate kinematic motions, cycle time and locations of components using geometric models and related data. It's for interference checks and productivity improvements. We expect that this virtual press shop helps us to achieve great savings in time and cost in many manufacturing preparation activities in the new car development process of automotive companies.

Digital technology has changed various aspects of the clinical dentistry. The intraoral scanner and Computer-aided design / Computer-aided manufacturing (CAD-CAM) technology are widely used in fabricating fixed prostheses and in implant surgery. These technologies greatly improved the efficiency of clinical and laboratory procedures. With all newly introduced software, devices, and clinical studies, digital technology has been actively applied in removable prostheses. It is now possible to fabricate the removable prostheses more quickly and easily through subtractive and additive manufacturing. Various clinical and laboratory protocols were introduced by many manufacturers. The purpose of this review is to summarize the literature on digital technology for fabricating complete denture with current status and future perspectives.
