Due to effects of milling vibration,instantaneous cutting poses of milling cutter and its teeth are complex and varying to cause steady change of instantaneous contact relation between milling cutter and workpiece,and make formation process of machining transition surface variable and uncertain.Here,the instantaneous cutting pose calculation model for milling cutter and its teeth under vibration was used to reveal influence characteristics of milling cutter instantaneous cutting pose bias on formation process of machining transition surface.Based on the mapping relation between instantaneous cutting pose of cutting edge and machining transition surface,variation characteristics of instantaneous position bias and angle bias of milling cutter were obtained using surface morphology detection results.A method to identify bias characteristics of instantaneous cutting pose of milling cutter was proposed.Test verification was conducted using response analysis and surface morphology calculation of milling cutter instantaneous cutting pose bias.The results showed that using the proposed model and method can effectively identify bias characteristics of instantaneous cutting pose of milling cutter under vibration.
