4.刃具计算中的几个问题 i.对于齿形曲线在相同的y_0值下有几个x_0值时往往造成接触方程在该区间无解,这可采用将o_2-x_0y_0坐标系转动一角度β,使得新坐标o_2-x_0~’y_0~’在该坐标下齿形曲线上的y_0~’对应有单一的x_0~’值。
4 cutting tool calculation of several issues i. For the tooth shape curve at the same y_0 value of a few x_0 values are often caused by the contact equation in this interval no solution, which can be adopted o_2-x_0y_0 coordinate system rotated by an angle β , So that the new coordinates o_2-x_0 ~ y_0 ~ ’in the coordinates of the tooth curve y_0 ~’ corresponding to a single x_0 ~ ’value.
