摘　　要：根据短道速滑冰刀的特点提出了用G1连续圆弧样条拟合短道速滑冰刀弧度曲线,以此建立短道速滑冰刀刃磨的数学模型。由于冰刀弧度曲线从弧顶向两边弧度半径递减,我们也提出了从弧顶向两边构造了半径递减的G1连续的圆弧样条的算法,并在华中数控系统HNC-12“小博士”上实现。A thought of grinding the blade curve of skates for short track speed skating with GI continuous arc splines is presented according to the skates blade properties. Because the radians or curvature radie of the blade curve are descending from its acme to both sides, so a descending radi~ sequence has been formed. An algorithm of constructing GI arc splines has also been implemented and tested on the NC system named Huazhong HNC-12 ＂Little Doctor＂.
