摘　　要：由于非球面零件本身的特殊性和复杂性,较球面零件加工更加困难。基于自主研发的切线法数控成形非球面机床,分析加工零件表面精度的影响因素。采用单因素法分别对砂轮参数、冷却液影响因素进行分析,着重分析砂轮磨损和磨轮转速误差。严格控制加工过程中所产生的误差,避免由于过多误差影响最终零件的面形精度和表面粗糙度,优化工艺流程。Due to its particularity and complexity, it is more difficult to process aspherical parts than spherical parts. Based on the self-developed tangent NC forming aspherical machine tool, this paper analyzes the influencing factors of the surface precision of the machined parts. The single factor method is used to analyze the parameters of the grinding wheel and the coolant. The grinding wheel wear and the grinding wheel speed error are analyzed. The errors generated during the machining process are strictly controlled to avoid the surface accuracy and surface roughness of the final part due to excessive errors, and the process flow is optimized.
