本文对测力仪结构进行分析，并对测力仪进行检测校核，成为一种新型测力仪，该新型车削测力仪有很多优点相比于原有车削测力仪：外形在车床中有相似结构，不影响整个车床运行，可直接装在车床上，更精确的显示出切削力的大小，传感器的灵敏度高，会使传感器具有良好的线性静态特性。传感器的技术指标全面达到CIRP．STCC规定的测力仪标准。采用了三个测量因素(切削深度ap，进给量f,主轴转速n，)和正交试验法对车削中的力进行实测。通过极差分析指出影响力的主次顺序为ap>f>n，并根据车削经验公式进行分析，从而说明了该车削测力传感器在实际测量中可以进行使用。

Abstract With cutting toward high-speed, high-precision, highly automated direction, the cutting process monitoring technology also raised higher and higher requirements, and a variety of automated machining equipment and manufacturing systems do not have the vast majority of machining process monitoring functions. To make these highly automated processing equipment, give full play to its excellent performance, to ensure processing quality, improve production efficiency, the tool condition monitoring and process control is increasingly important. A lot of research results show that small changes in cutting each state can be reflected by changes in cutting force, cutting force detection is one of the most widely used research and monitoring methods at home and abroad, but these methods are more or less at the time of use to change the original parts of the machine, the machine affect the system characteristics, especially for high-precision CNC machine tools greater impact. To solve this problem, an urgent need to design a dimensions, the use of state are similar to outer turning turning away from Cape dynamometer.
In this paper, using the finite element method dynamometer structure stiffness and stress analysis, and turning piezoelectric dynamometer structure to optimize critical dimensions, successfully developed a new type of piezoelectric turning into a dynamometer. The new turning dynamometer prominent advantages compared with the original turning dynamometer: it's close to the appearance of a common external turning tools can be directly clamped on the turret, and the actual state of the same cutting. It can be Installed On knife rest,so it is same wit practice stateofcutting.Sensitivity of dynamometer is more high, ，．The calibration results show that it has high static linearity, so the cutting dynamometer has fully reached the dylmmometer standard stipulated by CIRP-STCC．
