摘要: 在螺旋面成形磨削加工中,存在着由机械加工和安装工艺带来的系统误差,这些误差将直接影响成形磨削精度。提出了一种将系统误差作为恒定误差,并反馈到砂轮截形算法中,通过改变砂轮理论截形方程来消除误差的思想。研究了基于误差补偿的螺旋面成形磨削砂轮截形算法,并利用Visual C++开发出了一套通用性强,操作简便的螺旋面成形磨削砂轮修整软件系统。实验结果表明:磨齿精度达到6级以上。Abstract: In the process of helical surface form grinding,there are often systematic errors brought via the machining and installation process,and these errors are difficult to avoid and eliminate,which will directly affect the precision of form grinding. A new concept was proposed that the systematic errors was taken as a constant error and feedback to the algorithm of grinding wheel sectional shape,to eliminate the error by changing the theoretical equation of grinding wheel sectional shape. According to the theory of space meshing,the algorithm of grinding wheel sectional shape for helical surface form grinding based on the errors compensation was studied. Moreover,a set of versatility and simple to operate software system about the wheel dressing for helical surface form grinding was developed with VC + +. The experimental results show that the accuracy of gear grinding reaches level 6,the algorithm software is feasibility and practicability.
