该算式同样适用于圆柱体及其它四棱柱上天线。
These formulas aer also applicable to slots on the cylinder and otherquadraprism.
以车削正四棱柱为例，进行了误差分析，得到了刀具长度与工件尺寸和容许误差间的关系。
Then by taking the regular square prism as an example, the machining error is analyzed, and the relationship among the length of the lathe tool, the work dimension and the tolerance is obtained.
其扭力段由正四棱柱形改为正六棱柱形的，这样可以与有正内六角孔的风动扳手相插配使用，有提高工效的特点。
Therefore, the overthread screw tap can be matched with a pneumatic wrench having regular hexagonal holes via insertion, and the overthread screw tap has the advantage of high work efficiency.
