建立跟刀架在细长轴加工过程中所受力产生变形的力学模型,统计跟刀架在切削过程中的受力和细长轴的尺寸误差的几何分析3个模型,并从这3个模型来分析细长轴在车削过程中的误差与跟刀架所受力产生变形量的关系,最后通过试验来进行验证,得到的实测值与仿真值较为接近,故可通过此法来实时检测细长轴加工的尺寸误差。 The three models of the mechanical model, the geometric analysis of the force with the tool holder in the cutting process and the dimensional error of the slender shaft are established, Model to analyze the slender shaft in the turning process of the error with the turret force generated by the deformation of the relationship between the final test to verify that the measured value and the simulation value is closer to the real-time detection by this method Slender shaft machining size error.
