This method can be extended to deduce the solving equation for other hob blade curve of cylindrical worm.

该方法可以推广到其它圆柱蜗杆滚刀的刃廓曲线求解公式的推导。

A thought of grinding the blade curve of skates for short track speed skating with G1 continuous arc splines is presented according to the skates blade properties.

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。

This blade has a gentle, sloping convex curve to the point versus the concave curve of the clip blade.

相对于回形刀刃的凹曲线而言，这种刀刃具有一条延伸到刀尖的、温和的凸斜率曲线。
