Abstract
3축 파이프 형상절단기에서 다양한 접합형상에 대하여 모관과 지관의 접합궤적을 수학적으로 유도하였다. 그 접합궤적에 절단폭 등의 공구 보정하여 실제로 가공할 절단궤적을 결정하여 이 공구궤적에 해당하는 CL-data를 생성하고, 또한 공구 궤적을 확인하기 위하여 ghost 기능을 구현하였다. 생성된 CL data를 PLC의 위치결정제어 모듈에 로딩하여 동시 3축(<TEX>$\alpha$</TEX>, X, <TEX>$\beta$</TEX>축)의 이송을 제어하여 경로를 따라서 형상절단과 동시에 개선을 할 수 있도록 동시3축 파이프 형상절단 시스템을 개발하였다. Joint paths of master and branch pipes are induced mathematically for many kinds of joint patterns between both pipes in 3-axis pipe profile-cutting machines. By compensating them with a kerf width, the real cutting paths are determined, and their CL-data are generated, and the tool paths generated by CL-data are verified by a ghost function. A bevelling of welds is implemented through tilting a cutting torch in the <TEX>$\beta$</TEX>-axis direction for 8 sections in the chuck rotation of <TEX>$\alpha$</TEX>-axis. A PLC controls simultaneously position and velocity in a real time for <TEX>$\alpha$</TEX>, X, <TEX>$\beta$</TEX>-axis by loading CL-data generated. We developed the PLC-controlled 3-axis pipe profile-cutting system which can cut a master or branch pipe along the cutting path and simultaneously do a bevelling process.
