摘　　要：木工成型铣刀加工效率高、针对性强,广泛应用于木材成型面的铣削加工。由于其具有切削刃较长、形状跨度较大以及齿间的非对称性等特点,增加了制造难度。为此,提出了用于木工成型铣刀后刀面的刃磨模型。该模型以成型刃回转轮廓为基础,先确定砂轮的初始磨削姿态,再通过磨削抬角和摆角等工艺参数,实现砂轮姿态的调整,在保证后刀面磨削精度的基础上,避免磨削干涉和控制砂轮磨削区域。通过刃磨工艺优化,可实现砂轮的双侧磨削,提高磨削效率;通过磨削试验,取得了较满意的加工精度,从而验证了刃磨模型的正确性和有效性。Woodworking forming cutters are widely used in the milling of wood formed surfaces because of their high processing efficiency and strong pertinence.Due to the characteristics of long cutting edge,large shape span and asymmetry between teeth,the manufacturing difficulty of woodworking forming cutters is increased.In this paper,a sharpening model for the woodworking forming cutter flank is proposed.In the model,based on the rotary contour of the forming edge,the initial grinding posture of the grinding wheel is determined,and the grinding wheel posture and swing angle are used to adjust the grinding wheel posture.On the basis of ensuring the grinding accuracy of the flank,the grinding Interference is avoided and the grinding area of the grinding wheel is controlled.The sharpening process is optimized to achieve double-sided grinding of the grinding wheel and improve the grinding efficiency.Through the grinding test,the satisfactory machining accuracy is achieved,thereby verifying the correctness and effectiveness of the sharpening model.
