In the present work possibility using a regular microrelief (RMR), the working element of the tool generated on a surface, for reception of better surfaces processed apertures in process deforming insertion broaching is checked experimentally up. As a result of the spent researches are established corresponding dependences and high efficiency of application RMR of a profile of the tool in a certain range of tightnesses of plastic deformation is revealed.
Key words: plastic deformation, a regular microrelief, broaching process

Ragrin N. A. — Impact of machining conditions on the physical analogue of tool wear resistance at drilling

It is shown that cutting rate relevant to maximum durability of the fast-cutting twist drill when machining carbon structural steels remains invariable while feed, gage and hardness of work material change. Maximal resistance increases when gage is enlarged, and goes down when hardness of work material grows and feeding is altered relatively its best value.
