DETERMINATION OF THE ANGLE
ORIENTATION ABRASIVE GRAIN ABOUT VECTOR CUTTING SPEED ON THE round external and
internal grinding
S.N. Nizhnik
The intensity and
character of the contact processes are strongly influenced by such kinematic
and geometrical parameters of the formation as the position and orientation of
grain during grinding. We formulate the problem of the need to study changes in
the magnitude and direction of the absolute velocity of the cutting abrasive
grain, and grain orientation angle of cutting relative to the cutting speed.
The expressions that were obtained allows us to determine the variation of
cutting speed and changes within the contact angle of abrasive grain with the
surface being treated parts. Our studies make it possible to predict the
effectiveness of the abrasive tool with a circular outer and
inner surfaces of grinding parts.
Key words: wear of grain, cutting speed, angle orientation, top
of grain, abrasive grain, prediction, surface of workpiece.
