Problems with measuring coaxiality using the double-table dot method

2020-12-24View Original

Thread Content

Hello, seniors! Why is it necessary to connect the two halves of the coupling using elastic sleeve pin joints to enable synchronous rotation for measurement? Is it sufficient to rotate only one side for measurement? Could you please explain the principle behind it? Also, could you recommend some books on this topic! Thank you so much!

Eliminate radial surface errors of the coupling

Rotating one side measures the machining accuracy of the circular surface of the other half of the coupling
