진동 신호를 이용한 캠 프로파일 CNC 연삭기의 실험적 평가에 관한 연구

A study on the Experimental Evaluation for the Cam Profile CNC Grinding Machine using Vibration Signals

A earn profile grinding machine is a mandatory machine tool for manufacture of high precision contoured cam. Experimental evaluation of modal analysis is an effective tool to investigate dynamic behavior of a machine. This paper presents the measurement system and experimental investigation on the modal analysis of a grinding machine. The weak part of the machine is found by the experimental evaluation. The results provide structure modification data for good dynamic behaviors. And safety of the machine was confirmed by the modal analysis of modified machine design. Finally, the cam profile grinding machine was successfully developed.
