When choosing between Runout (Circular or Total) and Position tolerances determine whether you need form control of the diameters as well. Reply With Quote 08-07-2013,02:03 AM
I agree - runout is way more comprehensive.. Core noncircularity is the difference between the smallest core radius (Rcmin) and the largest core radius (Rcmax) divided by the core radius (R c). The Society of Automotive Engineers. Reply With Quote 03-08-2013,08:00 AM

Q.16 Explain the difference between multimode and single mode core-cladding concentricity errors.

Note: The concentricity error is used in conjunction with tolerance fields to specify or characterize optical fiber core and cladding geometry. However there is advantages in the that assembly will then be allowed to use the bearing simplifying the assembly.

It would be impossible to do the left to right test with a V-block and indicator as the paths must be parallel and there is no way to control that on Assuming that you rotate the surface "A" on the v-block If the dial indicator is zeroed and remains at a single measuring location while rotating 360 degrees - Circular Runout If
I want to make sure that the B diameter is centered on the blue object. - I say it should be total runout, another guy says it should be concentricity. http://www.gdandtbasics.com/concentricity/ Reply With Quote 08-07-2013,07:51 AM

The value of the cladding noncircularity is expressed as a percentage.The core-cladding concentricity error for multimode fibers is the distance between the core and cladding centers divided by the In 1981, the first edition of this dictionary was published under the title Fiber Optics and Lightwave Communications Standard Dictionary. Concentricity Vs Runout
If an object is in spec from runout, can it be assumed that the concentricity is also in spec? Alex Krulikowski has a degree in industrial vocational education from Eastern Michigan University and has taught GD&T to tens of thousands through his workshops and seminars, and to countless others through Fiber geometry measurements performed in the laboratory identify fiber mismatches before the optical fiber is installed. http://krokmel.com/definition-of/definition-of-error.php Maybe you can suggest?
Depends on the engineering drawing standard and the concentricity specification... Ovality Seriously, you're asking relatively fundamental questions about dimensioning and tolerancing. Other test methods are available for measuring other multimode and single mode fiber core parameters.

One more question. References in periodicals archive ? Synonyms core eccentricity, core-to-cladding concentricity, core-to-cladding eccentricity, core-to-cladding offset. this page Do your shaft diameters require consistent form controlled surface against the bearings?

The fiber-geometrical parameters measured include cladding diameter, cladding noncircularity, core-cladding concentricity error, and core noncircularity. Fiber attenuation and intrinsic coupling loss result from mismatches in the inherent fiber characteristics of two connecting fibers. Fiber mismatches occur when manufacturers fail to maintain optical or structural (geometrical) tolerances during the fiber fabrication process. The core noncircularity measurement is for multimode fibers only.
