Tolerances

What level of precision will be required of the fixturing?

Assume the tubes are perfectly circular, with the inner tube centered in the outer tube.

The center of the tubes is position x:0, y:0. If the center of rotation of the table is at position (X, Y), the clearance is given by:

At zero clearance, 2(rd) = 0.035 in; (X2 + Y2)1/2 = 0.0175 in.

If X = Y, then Xmax = (0.0175 in)(2-1/2) = 0.0125 in.

The maximum tolerance in centering the tube is 0.0125 inches in both X and Y. In only one dimension, the maximum tolerance is 0.0175 inches.

Subsystem Interaction

Will the subsystems fit together?

Inner Tube Centering

How much force is required to move the inner tube?
