Summary
-
1.
The thickness of the surface films formed during production decreases in a regular manner with decreasing roughness and with a roughness between 0.03 and 0.06 μ provides stable dimensions for gauge blocks.
-
2.
It appears that 0.02–0.03 μ is a critical value for roughness, and that if it is decreased during lapping in building up a block, a firm and close coupling is obtained, which, however, may lead to seizing (jamming) and the formation of a cold welded seam (speedy deterioration) on the measuring surface of the gauge, and if the roughness is increased, it leads to a loss of the wringing effect and a rise in the dimensions of the gauge block.
-
3.
The tangential resistance force may serve as a criterion of the tendency to wring.
-
4.
A specified method of lapping end gauges should be included in the instructions for checking them.
