Abstract

Abstract: In order to solve the problem in plunge type cylinder grinding caused by the traditional grinding removal efficiency model of grinding thermal deformation is different from the actual grinding， the traditional grinding removal efficiency model was modified based on the analysis of grinding thermal deformation mechanism. By analyzing the grinding thermal deformation and thermal deformation rate of grinding wheel and workpiece， the correction function was determined， the material removal efficiency correction model based on the thermal deformation was established. The model was verified by grinding experiment， and the results show that the model has higher accuracy.

Key words: plunge type cylindrical grinding, thermal deformation, material removal rate, experimental study

摘要： 为解决切入式外圆磨削加工中磨削热变形引起的传统磨削去除率模型与实际磨削偏差较大的问题，基于磨削热变形机理分析，对传统切入式外圆磨削去除率模型进行了修正。通过分析切入式外圆磨削过程中砂轮与工件的磨削热变形量及热变形速率，确定了修正函数，建立了基于磨削热变形的切入式外圆磨削材料去除率修正模型，并通过磨削实验对模型进行了验证。结果表明，修正模型具有更高的准确性。
