Firstly, this paper researched the forming mechanism of the helicoidal surface.
对螺旋面的成形机理进行了分析。
2
The helicoidal surfaces are produced mostly by form cutting with forming cutters of end mill type, side mill type or disc type.
螺旋面大多数是用球头铣刀、侧铣刀、盘形刀具成形加工出来的。

Except that the selected sliding surface is formed by logarithmic helicoidal surface-logarithmic helicoidal surface-plane, no other simplifications or assumptions are made.
