曲面的三阶局部切触在5坐标曲面加工中应用

The three order local contacte of the scurptrued surfaces in 5-axis machining of scuptrued surfaces

运用微分几何中的切触原理 ,研究了在多轴数控机床中刀具切削圆与零件曲面的切触条件和局部坐标系下的局部三阶切触条件 ,并用截形对刀具切削圆与曲面的贴近程度进行了分析。

This paper applied the contact principle of deferential geometry in to the 5-axis NC machining,researched the best contact condition of tool and the surfaces,analysis the contact degree of the intersection line of the cutter and the surfaces
