自20世纪70年代以来，多分量力传感器已经渗透到各种自动化产品中。然而，很少有人在市场上找到全组件传感器系统，用于机械加工中的切削力测量。本文设计并开发了一种新型的具有紧凑的单片弹性元件（EE）的六分量传感器系统，用于检测切向切削力Fx、Fy和Fz（即，沿着x、y和z轴的力）以及切削力矩Mx、My和Mz（即，关于x轴、y轴和z轴的力矩）。通过仿真驱动的优化，精心设计的EE的最佳结构参数。最后，制作了一个传感器原型系统，并将其应用于一台五轴并联加工中心。标定实验结果表明，该系统能够测量切削力和力矩具有良好的线性，同时最大限度地减少耦合误差。有限元分析（FEA）和校准实验研究验证了所提出的传感器系统，预计将被采用到加工过程中的高性能。
Multi-component force sensors have infiltrated a wide variety of automation products since the 1970s. However, one seldom finds full-component sensor systems available in the market for cutting force measurement in machine processes. In this paper, a new six-component sensor system with a compact monolithic elastic element (EE) is designed and developed to detect the tangential cutting forces Fx, Fy and Fz (i.e., forces along x-, y-, and z-axis) as well as the cutting moments Mx, My and Mz (i.e., moments about x-, y-, and z-axis) simultaneously. Optimal structural parameters of the EE are carefully designed via simulation-driven optimization. Moreover, a prototype sensor system is fabricated, which is applied to a 5-axis parallel kinematic machining center. Calibration experimental results demonstrate that the system is capable of measuring cutting forces and moments with good linearity while minimizing coupling error. Both the Finite Element Analysis (FEA) and calibration experimental studies validate the high performance of the proposed sensor system that is expected to be adopted into machining processes.
