【摘要】：由于铣刀在铣削过程中切削位置不同,固定型铣削测力仪将产生输出误差。为降低铣削位置变化对传感器输出的影响,研制了一种四竖直敏感梁结构的应变型固定式三维铣削测力仪。研究表明,当铣削位置范围限定时,该测力仪可以将输出信号误差维持在可用范围,并分别进行了静态力测量和动态铣削实验。在静态力测量实验中,在70mm×70mm×15mm工件上,传感器解耦偏差不大于5.58%;在动态切削实验中,使用相同加工参数在不同位置处铣削,传感器测得的铣削力峰峰值最大相差3.73%。对该铣削测力仪的研究为解决竖直方向高刚度的应变型固定式铣削力传感器的解耦问题提供了新的思路和参考。
[Abstract]:Because the cutting position of milling cutter is different during milling, the output error will be produced by the fixed milling dynamometer. In order to reduce the effect of milling position change on sensor output, a strain-type fixed three-dimensional milling dynamometer was developed for four-vertical sensitive beam structure. The results show that when the milling position range is limited, the error of the output signal can be kept in the usable range, and the static force measurement and the dynamic milling experiment are carried out respectively. In the static force measurement experiment, on the 70mm 脳 70mm 脳 15mm workpiece, the decoupling deviation of the sensor is less than 5.58. In the dynamic cutting experiment, the maximum difference of the peak value of milling force measured by the sensor is 3.73 when the same machining parameters are used in milling at different positions. The research of the milling dynamometer provides a new idea and reference for solving the decoupling problem of the strain-type fixed milling force sensor with high vertical stiffness.
