Abstract

As the culture of making things based on "do-it-yourself" (DIY) activity is increasingly promoted, the use of recent digital technologies and tools, including the 3D printer, have become widespread. However, the use of computerized numerical control (CNC) engraving machine is considered difficult because of the complicated procedures and specialized knowledge required for its operation. Therefore, this study aims to resolve the issue that limits the usability of the CNC engraving machine. This paper presents a novel CNC engraving machine system for non-experts based on human-centered design. First, the size and type of the workpiece and tool are reduced. Second, computer-aided process planning (CAPP) steps such as tool path generation, workpiece clamping, and corresponding coordinate system are automated by compromising productivity and efficiency. As a result, a CNC engraving machine system that can be easily used by non-experts was developed. This development has great significance in that it opens up the possibility of using the CNC engraving machine for a wider range of DIY activities.

DIY(Do It Yourself) 중심의 창작 활동이 확산되면서 일반 사용자들이 손쉽게 아이디어를 구체화 할 수 있는 환경이 마련되고 있다. 3D 프린터를 비롯한 디지털 기술과 도구의 대중화가 급속도로 진행되고 있는 반면, CNC 조각기의 경우 전문 지식의 부족과 복잡한 사용 절차로 인해 사용이 원활하지 않다. 이에 본 연구에서는 3D 형상 모델 파일만 선택하면 자동으로 가공이 가능한 CNC 조각기의 시스템을 개발하였다. 피삭재와 공구의 크기 및 종류를 제한하고, 생산성의 배제를 통해 공정 계획 및 공구경로 생성, 피삭재 고정, 피삭재 좌표계 파악을 자동화하였다. 그 결과 비숙련자도 혼자 충분히 사용 가능한 CNC 조각기의 시스템이 개발되었다. 이를 통해 기존보다 넓은 범위에서 다양한 사용자들이 사용할 수 있는 CNC 조각기의 발전이 기대된다.
