# How to calculate Cg and Cgk for a 2-Dimensional Area

M

#### marco-mi

I need to calculate the Ck and Cgk for a CCD-Camera-Intepretation measurement, which used to calculate the area of a part.

What i have known, the most examples for calculating of Ck,Cgk are one-dimensional(mm or cm). But i have never seen any example for calculation of Cgk for the Area mm2(square). There can be two Variance in the direction h and w. I dont know how to do with this.:mg:

Have you any idea?

best regards

.. caculatin of Cgk for the Area mm2(square). There can be two Variance in the direktion h and w. I dont know how to do with this.
IMHO I see two ways:

1- Just take the worst of all calculations, ie. if you have 0 as cgk in one dimmention, and 100 on the other, you sill will have 0 as your cgk, and most of the measures will be bad (maybe I am a little exagerated, but it's just for showing the point).

2- If the error effect of the part is reflected on the area, the area is the dimention that should be used to calculate the cg, cgk index.
