최현재,이영우,이주현,백지선,김동환,조규태,채흥석 한국정보과학회 2019 정보과학회 컴퓨팅의 실제 논문지 Vol.25 No.3

The evaluation of the quality of existing weapon system software was done by the Defense Acquisition Program Administration using a peer review based on the product checklist for each development phase. Since the product checklist is written at the level of checking the presence of contents in each chapter/section of the technical document, there was no quality evaluation such as completeness, consistency, and traceability of the modeling data. As a result, a technical document with different levels of modeling was written for each developer, and the evaluation by peer review was subjective, making it difficult to measure or quantify the consistency quality. It took a lot of time and effort as the review of the output was not automated. In order to improve the quality evaluation method of weapon system software technical documents, we propose the construction of a weapon system software reference model that expresses the items of technical document and the measuring quality metrics for quantitative evaluation. It also introduces the development measure of a quality measurement tool for quality evaluation automation. 기존 무기체계 소프트웨어 품질 평가는 방위사업청의 개발단계별 산출물 점검표를 기반으로한 동료검토를 통해 수행되었다. 산출물 점검표는 기술문서의 각 장/절에 대한 내용 유무 확인 수준으로 작성되어 모델링 데이터에 대한 완전성, 일관성, 추적성과 같은 품질 평가가 존재하지 않았다. 이로 인해 개발자 별로 모델링 작성 수준이 상이한 기술문서가 작성되었고, 동료검토에 의한 평가는 주관적이어서 일관성 있는 품질 측정 및 수치화가 어려웠다. 그리고 산출물들에 대한 검토가 자동화되지 못해 시간과 노력이 많이 소모되었다. 기존의 무기체계 소프트웨어 기술문서 품질 평가 방법을 개선하기 위하여 기술문서 구성 요소들을 표현하는 무기체계 소프트웨어 참조 모델 구성 방안을 제안하고 정량적인 품질 평가를 위해 품질 측정 메트릭 측정 방안을 제시하였다. 또한 자동화된 품질 평가를 위한 품질 측정 도구 개발 방안을 소개한다.

김동규(Dong Gyu Kim),사민우(Min-Woo Sa),허재영(Jae Young Heo),강익수(Ik Soo Kang),정윤철(Yun Chul Jung) 대한기계학회 2021 대한기계학회 춘추학술대회 Vol.2021 No.5

최근 CFRP의 사용량 급증으로 CFRP 절삭 시 품질 문제에 대한 관심이 매우 높고 이를 해결하기 위한 다양한 방법이 시도되고 있다. 그중 가장 대표적이고 쉽게 접근하는 방법이 절삭 공구를 최적화하는 것이다. 현재 산업 현장에서 사용되는 대표적인 CFRP의 절삭 공구는 다이아몬드 코팅 초경 공구와 다결정 다이아몬드 공구로 한정되어 있다. 본 논문에서는 이렇게 한정된 CFRP 용 절삭 공구를 대체할 수 있는 절삭 공구를 개발하기 위한 사전 연구로 기존 상용 절삭 공구의 절삭 특성을 파악해보았다. 절삭조건 중 절삭 속도, 절삭 깊이, 날당 이송량, 이송속도를 변수로 뒀고, 절삭공구의 종류에 따른 절삭력, Macro/Micro 표면 품질 평가를 통해 절삭 특성을 파악해보았다. 다결정 다이아몬드 공구는 다이아몬드 코팅 초경 공구보다 절삭력과 표면 품질 측면에서 우수함을 확인하였다. Due to the recent rapid increase in the use of CFRP, interest in quality problems during CFRP cutting are very high, and various methods are being tried to solve this problem. One of the most representative and easily accessible methods is optimizing the cutting tool. Currently, types of cutting tools for CFRP are limited in industrial sites, there are diamond coated carbide tools and polycrystalline diamond tools. In this paper, as a preliminary study to develop a new type of cutting tool that can be replaced for cutting tools for CFRP, the machining characteristics according to types of the cutting tool were analyzed. The cutting speed, depth of cut, feed per tooth, and feed rate were set as variables for cutting condition, and cutting characteristics were identified through the cutting force, and macro/micro surface quality. A polycrystalline diamond tool performance is superior to diamond-coated carbide tools in terms of cutting force and surface quality.
