This paper sets up an instantaneous cutting force model for a spiral cylindercutter by analyzing the linear relationship between micro-unit milling force and instantaneous uncut chip thickness.
By using it, the model of equal lead on the cutter can be applied to the cylinder, cone and sphere.
通过该模型，分别建立了柱面上、球面上和锥面上球头立铣刀的等导程螺旋线的数学模型。

The movement of whole-section tunneler is composed of forward movement of tunneler body pushed by the crowd cylinder and rotational movement of disk-cutter driven by the rotating motor.
