Abstract

PURPOSE: To properly grind a cylinder-shaped interior with the same angle continuously despite a change in diameter of a rotary grinder so that the interior is always kept in a condition of O taper, by amending a feed process for a rotary shaft support of a rotary grinder to the cutting direction.
CONSTITUTION: As the diameter of a rotary grinder is reduced from a prearranged length with a progress of grinding of a work, the time of transition from a precise grinding to a spark out is delayed from the times corresponding to P2, Q2 to the times corresponding to P2', Q2'. As for the spark out in this case, it progresses starting from a cutting quantity corresponding to point P2', through the course shown with dotted line d", up to the prearranged final cutting quantity corresponding to point 3'. However, magin ε' by this spark out is less than the former one ε. The theory applied to this point is that in case a spark out margin is reduced from ε to ε', a cylindrical accuracy is improved correspondingly to this reduction and the degree of this improvement keeps a certain relationship to the reduced cylindrical accuracy due to a reduction in the diameter of a rotary grinder.
