摘要
五轴联动计算机数控激光加工系统是多功能综合性的机电一体化设备 ,可进行平面和三维曲面的切割、焊接等激光加工。传统的CNC系统往往只提供直线和圆弧插补功能 ,不能满足CAD系统的曲线和曲面造型能力对CAM系统的要求。本论文针对复杂轮廓零件数控加工的需要 ,提出了一种新的空间曲线B样条插补五轴联动算法 。
Five-axises linkage CNC laser-machining system is a kind of mechanical and eletronic muti-functions equipment,which can carry on incising and welding of plane and 3D surface.Traditional CNC can only provide the function of line or circle interpolation.This can not meet the needs of sculpture capability of CAD system for curve and 3D-surface.This paper provide a new 3D curve interpolation algorithm of B-spline for five-axises CNC System and emulate this algorithm on Matlab successfully.
