重磨螺旋槽滚刀时砂轮修形自动编程系统的开发

Development of Grinding Regrinded Automatic Programming System when Regrinding Hob with Helix Flute

磨削螺旋槽滚刀前刃面时,为获得砂轮母线需要通过调整靠模圆柱的角度,反复试切,影响了生产效率。针对该问题本文以VC++为开发工具,根据开刃磨过程中刀具前刃面的成形原理,建立了计算砂轮理论廓形的数学模型,精准地计算出砂轮的廓形,实现了数控开刃磨砂轮廓形数控加工NC代码的自动编程。

The domestic grinding wheel-profile is formed by adjusting the angle of cylindrical profile model when regrinding gear hob with the large helix flute.The method need repeat trial cut and result in low efficiency.In order to improve the efficiency of processing,this paper uses VC＋＋ as the developing tool to establish the mathematical model of grinding wheel profile in according to forming principle of the rake face of gear hob and accurately calculate grinding wheel-profile.An automatic programming system of calculating grinding wheel-profile and automatically generate NC code is developed.
