利用激光狭缝扫描原理和光电传感技术，提出了一种用于测量大型回转体类零件圆度误差的激光扫描非接触测量方法和测量系统。
A laser scanning non contact measuring method and a measuring system for the roundness errors of large sized rotating parts are presented.
因为回转体在特殊情况下投影为圆，此类问题就转化为求圆的半径、圆心及切线了。
On special conditions, their projections are circular, these problems turn into the solutions of the circle radius center and tangent.
由于受到材料成形极限等因素的限制，成形此类回转体零件往往需要采用多道次旋压工艺。
Because of the limitation of material forming limit and other factors, it is necessary to produce this kind of parts by multi-pass spinning technology.
