High speed shaping cut - Large circumference feed -
Conventional feed
Cutting load is concentrated at cutter tooth tip.
The cutter flank wear at trailing side tends to increase due to thinner longer chips.
Large circumference feed
The chips are generated thicker than Conventional feed.

As graphs are shown,both flank wear and crater wear with the larger circumference feed are smaller than the ones with smaller feed.
NOTE: In case of which shaping is the final process for gears and the cutting surface roughness doesn't
meet the accuracy, the feed rate should be smaller. For those which final process is shaving or grinding,
the surface roughness is usually out of scope on the shaping process.
