PERFORMANCE TEST FOR CUTTING OILS Available to Purchase

A book published by the American Society for Testing Materials, (A Bibliography On Cutting of Metals by O. W. BOSTON) lists over four thousand papers in the field of metal cutting and shows how difficult it is to devise a laboratory performance test for assessing the value of metal cutting fluids. The difficulty experienced by experimentors in this field is due to the number of variables which are not easy to control, making such tests too long to be practicable.
