TotalDMIS理论值与实测坐标系无关

TotalDMIS专业、灵活、高效的DMIS编程开发平台

首款通过德国PTB"双认证"的国产三坐标测量软件

1）通过德国PTB"高斯-最小二乘法"认证

2）通过德国PTB"切比雪夫-最小区域法"认证

有些DMIS软件系统因为设计原因, 在切换坐标系后会影响到理论值的正确性. 例如下面的DMIS程序:

DMISMN/'Test',05.0
UNITS/MM,ANGDEC
RECALL/D(MCS)
$$定义一个初始坐标系
D(Crd1) = ROTATE/XAXIS,45.0000
$$定义一个圆元素
F(Cir1)=FEAT/CIRCLE,INNER,CART,100, 200, 300, 0.0, 0.0, 1.0, 30
FA(Cir1)=FEAT/CIRCLE,INNER,CART,100.03, 200.02, 300.45, 0.0, 0.0, 1.0, 30
$$定义第二个坐标系
D(Crd2) = TRANS/XORIG,FA(Cir1),YORIG,FA(Cir1),ZORIG,FA(Cir1)
$$定义输出的公差
T(CORTOL1)=TOL/CORTOL,XAXIS,-0.1, 0.1
T(CORTOL2)=TOL/CORTOL,YAXIS,-0.1, 0.1
T(CORTOL3)=TOL/CORTOL,ZAXIS,-0.1, 0.1
V(TEXT)=VFORM/ALL
DISPLY/TERM,V(TEXT)
OUTPUT/FA(Cir1),TA(CORTOL1),TA(CORTOL2),TA(CORTOL3)
ENDFIL

特征圆Cir1的X,Y,Z坐标公差正确的值应该都是0.0, 而有的DMIS软件系统会因为坐标系的原因, 计算的X,Y,Z坐标公差为错误的0.03, 0.02, 0.45

这些有问题的DMIS软件必须要在计算公差之前, 重新定义一遍特征的理论值后才能正确计算公差. 这就需要用户重新计算理论值, 这样做不仅麻烦,易错, 而且程序也会变得复杂臃肿

TotalDMIS严格遵循DMIS标准, 无需用户对DMIS代码进行任何的添加和修改. 即可计算出正确的公差值.
