摘要
针对磨削球头立铣刀周刃偏心型后刀面的工艺参数化定义不完善,由砂轮姿态突变导致的后刀面磨削宽度不均匀等问题,提出了一种球头立铣刀后刀面采用平行砂轮加工的磨削轨迹算法。该算法首先建立了一种具有齿偏中心量的球头立铣刀刀刃曲线模型,根据模型结构对相关坐标系及其转换关系进行了定义。随后,在描述砂轮姿态的坐标系下构建了砂轮初始磨削姿态模型以及对其工艺参数进行了定义,并根据转换关系对砂轮磨削姿态进行了统一表达。最终,算法的验证通过仿真及实际加工环境进行,并通过测量仪器对后刀面相关参数进行了测量,算法的可行性及准确性得到了进一步验证。
Aiming at the problems such as incomplete process parameter definition of the eccentric back cutterface of ball end milling cutter and uneven grinding width caused by abrupt change of wheel attitude,a grinding trajectory algorithm of parallel grinding wheel was proposed for the back cutter face of ballend milling cutter.Firstly,a ball-end milling cutter blade curve model with tooth deflection was established,and the correlation coordinate system and its transformation relationship were defined according to the model structure.Then,the initial grinding attitude model of grinding wheel was constructed and its process parameters were defined under the coordinate system describing the grinding wheel attitude,and the grinding attitude of grinding wheel was expressed uniformly according to the transformation relationship.Finally,the verification of the algorithm was carried out through simulation and actual machining environment,and the relevant parameters of the rear cutter face were measured by measuring instruments,and the feasibility and accuracy of the algorithm were further verified.
