A quadratic model of predicting helical milling force was researched. The effects of spindle speed, feed per tooth, and axial and radial depth of cut were analyzed.

通过统计学中的响应曲面法建立了螺旋铣削过程中切削力的二阶模型，并分析了主轴转速、每齿进给量、轴向和径向切削深度等因素对切削力的影响。

The vibrations are caused by spindle curved tooth meshing impact when the gap between work roller bearing block and frame is oversized.

主要振因是当工作辊轴承座与牌坊之间间隙过大时，接轴弧形齿的啮合冲击将激起轧辊横向振动。
