... in Ref 25 . The question was considered more recently and investigated as a means of speeding up fretting wear tests, assuming that high frequencies had no significant effect ( Ref 25 ). The range of frequencies investigated was from 10 to 10 4 Hz, using steel specimens in a crossed-cylinder contact...

... The hardness of carbon and low-alloy steels has a greater effect than composition on reamability. The results of tests to determine the effect of workpiece hardness in reaming are shown in Fig. 1 . Speed, feed, metal removal rate, and reamer life were compared for reaming holes of 6.4 and 13 mm ( 1 4...
