摘　　要：在工程数学中经常涉及到空间坐标转换 ,常规的方法是几何法 ,就是通过坐标系的平移 ,旋转来求得最终结果。这种方法不仅不直观 ,而且难以理解、计算量大、容易出错。经过摸索 ,本人发现运用矢量法能够简化这一过程。并且以这种方法建立了圆柱铣刀的数学模型。In engineering mathematics space coordinate translation is often dealed with. The final result always calculated though translating and rotating the coordinate system. This approach is not only difficult to understand, easy to make mistake but also has large calculation. After a long time practice,a intuitive approach that is vector approach was put forward to simple the complex course and establish the mathematics model of the column helix milling cutter.
