As shown in the measurement diagrams of Fig. 5b, Fig. 6b, and Fig. 7b, the sample plate to be tested is arbitrarily placed on the glass workbench of Wangongxian, and fixed with plasticine, and the focal length of the instrument is adjusted to make the sample line show a clear image.
Here, taking Fig. 7 as an example, on each arc and the reference side (straight line) during measurement, each point is collected by 12 points, and the number of each point is as shown in Fig. 7b. The coordinate values ​​of each point are as follows:
The program of measurement and solution is to find the coordinates of the intersection of arc and arc: select "circle and circle"; find the intersection size: select "point line distance"; find the radius of the arc: select "N point circle". After confirming, enter the parameter → Enter → the screen displays the result.
Finally, if you need to print the results you want, select “Print†to print out the measurement results.
