Research on step length of NC machining curved surface

The step length is one of the most important parameters of NC machining curved surface. If it is too large, it can’t meet the demand of the manufacturing precision; if too small, it will prolong the producing time. The step length is always decided by the experience we had in the usual manufacture. Although some 3D auto-programming software can be used to calculate, but the functions are still not good enough, In this thesis, we will do some theoretical analysis, find the calculating results in the form of electric tables, set up the row distance parameters according to the requirements of the manufacturing quality and the parameters will be treat as the references of parameters settings in the NC machining.
