Abstract

The fourth industrial revolution is noted. It is a smarter factory. At present, research on CNC (Computerized Numeric Controller) is actively underway in the manufacturing field. Domestic CNC equipment, acoustic sensors, vibration sensors, etc. This study can improve efficiency through CNC. Collect various data such as X-axis, Y-axis, Z-axis force, moving speed. Data exploration of the characteristics of the collected data. You can use your data as Random Forest (RF), Extreme Gradient Boost (XGB), and Support Vector Machine (SVM). The result of this study is CNC equipment.

4차 산업혁명이 주목받고 있다. 특히 스마트 팩토리는 제조 분야에서 그 필요성이 강조되고 있다. 현재 제조 분야에서 CNC(Computerized Numeric Controller: 컴퓨터 수치 제어)에 관한 연구가 활발히 진행 중이다. 국내에서는 CNC 설비에 음향 센서, 진동 센서 등 여러 가지 센서를 부착하여 소음, 진동 등 설비 관련 데이터를 수집하는 방안에 관한 연구가 존재한다. 본 연구는 CNC 머신에서 발생하는 데이터를 중심으로 머신러닝 기법을 활용하여 설비 가동 조건이 공구 마모도에 미치는 영향을 분석한다. CNC 설비에서 발생하는 X축, Y축, Z축의 힘, 이동 속도 등 다양한 데이터를 수집한다. 데이터 탐색 기법을 통해 데이터의 특성 및 분포를 분석하였다. 데이터를 RF(Random Forest), XGB(Extreme Gradient Boost), SVM(Support Vector Machine)을 이용하여 CNC 설비 가동 조건이 공구 마모도에 미치는 영향을 분석하였다. 본 연구의 결과는 CNC 설비 가동에서 최적의 조건을 찾고, 이를 바탕으로 품질 향상 및 기계 손상을 예방하는데 활용될 수 있을 것으로 기대된다.
