統計的手法による研削機構の考察(第3報)

二,三の実験的考察

抄録

In this paper, with relation to the theoretical analyses on grinding mechanism which were described in the previous reports, following experiments are performed:
(1) Measurement of the tip angle and the distribution density of cutting edges. Special mention is made to the difference between results of surface roughness method and replica method in measuring the distribution density of grain tips.
(2) Measurements of the cutting pulses by grain tips in grinding. Successive cutting edge space is also discussed under the assumption that conical grain tips distribute three-dimentionally at random in grinding wheel. The experimental results agree approximately with the theoretical in consideration of difficulties of measuring cutting pulses when the magnitude or the spacing of cutting pulses is very small.
