【摘要】 从理论和实践上论述了具有丝半径、放电等各种间隙补偿功能的曲线合成插补理论。该理论直接利用轮廓曲线和丝圆的信息 ,间接实现任意直线和二次曲线的等距曲线的插补 ,而不需计算等距曲线。有效地避免了传统的计算等距曲线产生的计算误差 ,提高了机床的控制精度 ,解决了该理论涉及的有关问题 ,并在慢走丝线切割机床加工中得到了应用。更多还原

【Abstract】 A curve synthetic interpolation theory with compensation of wire radius and spark gaps had been expounded theoretically and practically. With the theory,the offset distances of any straight lines and quadratic curves could be interpolated indirectly with the help of outlines and wire circle informations,it was unnecessary to calculate offset curves. This method avoided effectively traditional calculating errors of offset curves, the control precision of LWEDM has been increased, problems dealing with the theory has been solved in this paper,and the theory has been used in LWEDM.更多还原
