对于环形零件壁厚差，其实是内外圆相对应点之间的距离。1.平面，圆 建立零件坐标系。2.自动测量外圆，内圆。3.评价内外圆相对应触测点距离。 内外圆测量完毕后，分别评价外圆的点1到内圆的点1之间的距离，然后评价外圆点2到内圆点2之间的距离…依此类推直至最后一点即可评价出环形零件壁厚差。第一步，快速取出测量元素的测量点。 双击元素，在元素的属性页中拖放到点元素节点下，也可以直接拖放输出测量点（属性页中显示的数据是没有经过测头补偿的，而在点节点下是经过测头补偿的）。第二步：评价时是内外圆的点与点之间的对应。$$/* HeaderDMISMN/'Created by [爱科腾瑞科技(北京)有限公司-091520-DEMO] on 星期四, 五月 14, 2020', 4.0UNITS/MM, ANGDEC, MMPSWKPLAN/XYPLANPRCOMP/ONTECOMP/ONFLY/1.0000MODE/MANSNSET/APPRCH, 2.0000SNSET/RETRCT, 2.0000SNSET/DEPTH, 0.0000SNSET/SEARCH, 10.0000SNSET/CLRSRF, 20.0000RECALL/D(MCS)SNSLCT/S(L20-D2.0)GEOALG/BF, LSTSQRGEOALG/ANGLB, DEFALTGEOALG/CIRCLE, LSTSQRGEOALG/ARC, LSTSQRGEOALG/PLANE, LSTSQR$$$$$$*/MODE/MANF(PLN1)=FEAT/PLANE,CART,0.5399,-2.7834,0.0000,0.0000,0.0000,1.0000$$ Measurement points are created through actual pointsMEAS/PLANE, F(PLN1), 4 PTMEAS/CART, -12.9454, 16.2044, -0.0000, 0.0000, 0.0000, 1.0000 PTMEAS/CART, -15.1920, -14.3728, -0.0000, 0.0000, 0.0000, 1.0000 PTMEAS/CART, 10.0229, -18.5494, -0.0000, 0.0000, 0.0000, 1.0000 PTMEAS/CART, 20.2739, 5.5841, -0.0000, 0.0000, 0.0000, 1.0000ENDMESD(CRD1) = DATSET/FA(PLN1), ZDIRD(CRD1) = TRANS/ZORIG, FA(PLN1)F(CIR1)=FEAT/CIRCLE,INNER,CART,0.0000,0.0000,-2.1950,0.0000,0.0000,1.0000, 39.0000$$ Measurement points are created through actual pointsMEAS/CIRCLE, F(CIR1), 4 PTMEAS/CART, 4.8289, 18.8926, -2.1950, -0.2476, -0.9689, -0.0000 PTMEAS/CART, 18.3782, -6.5185, -2.1950, -0.9425, 0.3343, -0.0000 PTMEAS/CART, -8.0859, -17.7445, -2.1950, 0.4147, 0.9100, -0.0000 PTMEAS/CART, -19.3196, 2.6465, -2.1950, 0.9907, -0.1357, -0.0000ENDMESD(CRD2) = TRANS/XORIG, FA(CIR1), YORIG, FA(CIR1)MODE/PROG,MAN$$ MACRO: EASI_CLEARPLN_GOTO$$ FUNCTION: CLEARANCE SURFACE IMPLEMENTATION$$ Move machine CLEAR SURFACE DIST above the current clear surface $$ plane and then move machine parallel to the clear surface plane $$ ALL Macro parameters are in PCS and Current UNITS$$ Last update: 3-1-04 Add mode checking. only works in PROG MODE$$ Last update: 8-24-04 Clear position is based on the surface of$$ $$ This sample DMIS Macro is provided by External-Array Software, Inc.$$ It should be modified for your own use.
