铣削加工磨牙冠的表面粗糙度分析

Surface Roughness Analysis on Milling of Molar Crown

以口腔修复中具有代表性的磨牙冠为例,对数控加工中影响加工件表面质量的理论因素给予了详细的分析,并结合实际加工条件,选择合适的加工参数加工出实物。用三维形貌仪测量工件的表面粗糙度,并对数值进行分析,结果表明磨牙冠的加工符合设计要求。该分析方法对其他同样复杂的零件的加工具有参考价值。

Taking a molar crown as an example,a method was used to analyze theoretically the factors which influenced on surface quality in milling the molar crown.Then the appropriate processing parameters were selected considering the actual fabriction conditions.The surface roughness of workpiece was measured with 3D Profiler.The test results show that the surface roughness is consistent with design requirements.This analysis method has reference value for machining parts with complex structure.
