摘　　要：球头立铣刀是加工复杂高精度曲面的重要刀具。在磨削加工球头立铣刀的制造过程中,随着磨削时间的增加,砂轮会出现磨损,球头立铣刀的刃形曲线会随之发生变化。文章以SolidWorks为开发平台,基于球头立铣刀前刀面的磨削加工运动关系,利用Visual Basic语言进行二次开发,开发出球头立铣刀前刀面的磨削仿真加工系统和刀具参数分析系统,分析了砂轮磨损对球头立铣刀刃带宽度和刃形曲线的影响。分析结果可为实际加工过程提供理论指导,有助于制定正确的磨削制造工艺,并为后续制定正确误差补偿策略提供重要指导。The ball-nose end milling cutter is an important cutting tool which is used to cut the complicat- ed high-precision curved surface. In the manufacturing process of grinding ball-nose end milling cutter, as the grinding time increased, the wheel will be wear, the edge curve of ball-nose end milling cutter will also change. In the paper, the grinding simulation system and parameters analysis system of rake face of ball-nose end milling cutter was established, the means of Visual Basic, based on SolidWorks software platform. Effects of grinding wheel wear on the edge strip width and edge curve of ball-nose end milling cutter was investigated. The obtained results can provide theoretical guides to the manufacturing process of ball-nose end milling cutter, and provide the guidance for the follow-up to develop the correct error compensation strategy.
