卧式铣床支架的支承轴承的精度会影响刀杆的回转精度，从而影响孔的尺寸精度和圆柱度。

The precision of the support bearing of the horizontal milling machine bracket affects the rotation precision of the cutter rod, thus affecting the dimension precision and cylindricity of the hole.

同时解决了曲面法矢垂直于回转平面时刀轴矢量难以确定的关键问题。

Also, a solution is offered to solve the problem of generating tool axis vector when the surface normal ts perpendicular to rotary plane.
