摘要
钻尖容屑槽的主要作用是改善排屑条件,提高钻头耐用度,具有结构复杂、对精度要求高等特点。为提高钻头的结构扩展性以及加工精度,求解出钻尖容屑槽在数控磨削过程中的砂轮轨迹,定义了容屑槽的结构参数、坐标系、坐标系变换矩阵以及砂轮初始姿态,并计算了砂轮的磨削轨迹。在此基础上,借助运动学原理基于工件坐标系的砂轮磨削位置和姿态的计算方法,采用坐标变换矩阵描述砂轮运动方式。基于VC++环境开发了相应的计算程序,进行了磨削加工仿真和测试,并验证了算法的计算精度和有效性。
The drill point chip flute has the characteristics of complex structure and high precision requirements,to improve the chip removal conditions and increase the durability of the drill.In order to improve the structural expansibility and machining accuracy of the drill bit,the grinding wheel trajectory of the drill tip chip flute in the CNC grinding process is solved.The structural parameters,the coordinate system,coordinate system transformation matrix of the chip flute and the initial posture of the grinding wheel are defined.The grinding track of the grinding wheel is calculated.On this basis,the coordinate transformation matrix is used to describe the motion mode of the grinding wheel,and the grinding position and attitude of the grinding wheel are calculated based on the workpiece coordinate system with the help of the kinematics principle.Based on the VC++environment,the corresponding calculation program is developed,a series of grinding processing and tests are carried out,which verifies the calculation accuracy and effectiveness of the algorithm.
