摘　　要：根据刀剪端面磨削加工的工艺特点,分析了磨削加工参数与设计参数之间的函数关系;针对不同特征的刀剪磨削面,提出二轴联动插补法、刃口线垂直平移法和多轴联动加工法三种加工方法,指出了手工编程和软件绘图编程的技术要点;并对端面磨削加工方法进行了磨削实验。实验验证表明,磨削出的刀具刃口线和轮廓线形状符合设计要求,刃口厚度一致,磨削表面粗糙度达到Ra 0.4μm,尺寸精度保持在±0.01 mm范围内,所设计的加工工艺方法有效提升了刀剪产品的质量,提高了生产效率。Based on the process characteristics of surface grinding for knives and scissors,the functional relationship between the grinding parameters and design parameters is analyzed in this paper.According to the different features of the cutting and grinding face,three processing methods are presented,including the two-axial interpolation method,the cutting edge vertical translation method and the multi-axial joint processing method.Then the points of manual programming and software drawing programming are pointed out.The experimental verification shows that the grinded cutting edge lines and contour shapes meet the design requirements,the thickness of cutting edge is consistent;the grinding surface roughness of scissors reaches Ra 0.4 μm,and the dimensional accuracy is within ±0.01 mm.It effectively improves the quality of knives and scissors products,as well as the production efficiency.
