Alignment of Gear part

atul01011992
Daer all,

I am new guy for this user forum, currently I am using PC-DMIS in Camio 8.3. (Nikon Make)
Recently, I found a problem with a alignment issue for my product. It is about a alignment of [A-B I C I D-E ] of part. Please refer to attached file for details. In that A & B are the circles through which we are going to construct a 3S line as a primary datum, then moving ahead C is plane as a secondary datum and lastly D & E are tooth width, from which we need to construct a line through theirs mid points. As in that I don't understand how to do alignment of this part ?
Because there are 2 lines and 1 plane. and mostly unluckily axis of 3D line and Plane is same. Its conflicts my alignment. CAMIO is not allowing to add 2 line 1 plane alignment anyway.

Any help would be greatly appreciated.


Thank you in advance. Slight smile

Best Regards,​​​​​​​

  • Well, as the datums lock as many degrees of freedom they can (that are not already locked), but no more, I don't see the problem (see my edit above), C is only locking the coordinate. Ninja said the same thing as answer to a duplicate post. There is no law that the datums should be in the order level, rotate, origin - here we have level and part origin, origin, rotate.

    Remember that the C plane should be measured/constructed as "tangent plane, perpendicular to A-B" (I.e. all we need is the Z coordinate of the "high point" of the plane).

    @ - it is not a good idea to post the same question in a lot of threads - people will waste their time answering something that has already been answered/discussed elsewhere.
