Optimal cutting speed for the observed material at constant durability can be detected from the relation. However, longterm test requires longer time of machining and consumption of material. Therefore a number of authors have observed the possibility of shortening the tests. There is a widespread opinion that shortened methods posses low reliability. On the other hand, those methods cannot be replaced in the conditions of actual operation. Some of them are analysed and modified as follows.
