hob grinding as gear generation is a quite aggressive technique do hobs suffer great wear on the job. therefore frequent grinding/re-sharpening is mandatory in order to keep up the tool in line with high precision standards.
hob resharpening machines are numerically controlled nowadays with a least four nc axes as shown in figure n 11. the a axis manages the indexing of the gashes and when interpolated with the x axis it is possible to generate the feed for working helical gashes. the z axis is a positioning axis and works according to the hob diameter and lastly the
