Distributions of flash temperature T_f of on tooth flanks of spur and helical gears were calculated. The concentration of T_f at the beginning point of contact on leading side edge of tooth and at the ending point of contact on trailing side edge of tooth was found on helical gears, and the maximum T_f appeared on helical gears of small overlap ratio. By computer simulation for progress of scoring and by tooth flank observation of gears scored on test bench, the fashion of scoring progress on tooth and it proceeds in longitudinal direction on tooth flank of approaching contact, and then it occurs at the ending point of contact on trailing side edge of tooth and it proceeds on tooth flank of recess-contact in counter longitudinal direction.
