摘　　要：根据石英晶片的晶体变形效应(拉压效应和扭转效应)研制出一种新型钻削测力仪。轴向力测量晶组采用2片XO°切型的石英晶片对装;扭矩测量晶组仅由3片具有扭转效应的YO°晶片组成,通过4片电极两两交错连出单一测量电极,省去了绝缘装置,同时使电荷灵敏度增大1倍。标定结果表明:该测力仪轴向力和扭矩的线性度和重复性均小于1%,横向干扰小于5%,该测力仪的各项静态指标均达到了CIRP-STCC标准。Based on the piezoelectric deformation effect （ tensile and compressive effect and torsional effect） of the quartz disc, a new-type drilling dynamometer was designed. The thrust measuring cell was made of two XO-Cut quartz discs. The torque measuring cell consisted of only three YO-cut discs and four semicircle electrodes. The four electrodes were reciprocally connected to constitute a single measuring electrode,which can not only eliminate the insulate device, but also double the charge sensitivity. The static calibrations results show that both the linearity and repeatability of thrust and toque are less than 1% ,and the cresstalks are less than 5% ,which reached the dynamometer standard stipulated by CIRP-STCC.
