In this paper, we present a case study of developing MVIS (Machine Vision Inspection System) designed for exterior quality inspection of stamping dies used in the production of automotive exterior components in a small to medium-sized factory. While the primary processes within the factory, including machining, transportation, and loading, have been automated using PLCs, CNC machines, and robots, the final quality inspection process still relies on manual labor. We implement the MVIS with general- purpose industrial cameras and Python-based open-source libraries and frameworks for rapid and low-cost development. The MVIS can play a major role on improving throughput and lead time of stamping dies. Furthermore, the processed inspection images can be leveraged for future process monitoring and improvement by applying deep learning techniques.

Recently, elevator inspection and self-examination were strengthened through the revision of the Elevator Safety Management Act, but there have been no significant reduction in serious accidents and major failures. Therefore, the government intends to lay the foundation for reflecting the safety quality rating system, which adjusts the elevator inspection cycle, as a policy to induce safety management of preemptive and active management entities. This study systematically reviewed and classified the safety quality rating system for elevator inspection cycle adjustment in previous studies, collected expert opinions, and reconstructed the key items into realistic evaluation items, and evaluated and scored the relative importance of each factor through the AHP technique.

In this study, a study was conducted to improve the reliability of the valve by developing a valve leakage and reliability measurement system designed to secure the high quality and reliability of the butterfly valve. The system measuring the torque required for valve opening and closing operation, and was configured to operate after multiple opening and closing of the valve to check for leakage of the valve. Finally, a system that can perform efficient work in terms of productivity was developed by enabling leak inspection, torque measurement, and reliability inspection through one integrated system.

본 조사는 일본의 쌀 검사 제도와 품위 등급 규격에 대한 동향을 살펴보고 그에 따른 내용을 파악하여 국내 쌀 산업 발 전 방향에 도움이 될 수 있는 방안을 모색하고자 수행하였다. 1. 농업 경쟁력 강화 프로그램으로 2016년부터는 농산물 규격 검사의 간소화로 최근에는 곡물 검사장에 곡물 판별기를 활용하여 뉘, 맥류, 뉘 이외 곡물 등을 이종 곡립으로 통합하여 5% 이내로 개정하였다. 2. 쌀에 대한 손실 방지를 위해 정미의 포장 표시를 년·월· 일 표시에서 상·중·하순으로 개정하였다. 3. 일본은 매년 생산된 현미 품위 생산량과 등급 비율을 공개 하고 있으며, 1등급 쌀을 대상으로 식미 랭킹을 선정하고 있다.

Recently, due to the aging of workers and the weakening of the labor base in the automobile industry, research on quality inspection methods through ICT(Information and Communication Technology) convergence is being actively conducted. A lot of research has already been done on the development of an automated system for quality inspection in the manufacturing process using image processing. However, there is a limit to detecting defects occurring in the automotive sunroof sealer application process, which is the subject of this study, only by image processing using a general camera. To solve this problem, this paper proposes a system construction method that collects image information using a infrared thermal imaging camera for the sunroof sealer application process and detects possible product defects based on the SVM(Support Vector Machine) algorithm. The proposed system construction method was actually tested and applied to auto parts makers equipped with the sunroof sealer application process, and as a result, the superiority, reliability, and field applicability of the proposed method were proven.

  Many producers put sampling inspection policy into the way of their convenience. Examples of the convenience are irregular lot size and too small sample size. Because they don"t use a standard sampling inspection policy, they can not guarantee the quali

This paper aims to explore effective ways to improve inspection service and develop customer-centered inspection administration, by carrying out a case study on the K Society of Ship Inspection. The methods applied for this research project are as follows, 1) sector-based examination of the existence of the ISO 9001 system; 2) evaluation or the operation or the system; 3) conduction or a survey questionnaire with the participation of all staff and inspections institutes to analyze customer satisfaction of their inspection service, and 4) statistical analysis of the data collected from the survey questionnaire.
