| green hobbing Just a definition that may help Explanation: Hobbing – a way of using a hardened specially shaped cutter called a hob to cut gears or spline teeth. In the process, the teeth are being generated by the hob as it gradually feeds across or into the blank as the hob and the blank move in a timed relationship. Usually, the tooth profiles that are produced are different from the form of the hob. http://www.imti21.org/documents/taxglossary.pdf -------------------------------------------------- Note added at 18 mins (2003-12-16 17:12:40 GMT) -------------------------------------------------- Skiving or Re-hobbing Capability Skiving or carbide re-hobbing is cutting gears after heat treatment. It is a unique process that uses the same machine as \"green\" hobbing process. This process allows eliminating heat treat distortions without having to resort to gear grinding or other expensive gear finishing operation. This process has been steadily gaining popularity during last 20 years. http://www.bodinegears.com/capabilities.htm During green hobbing, the selection of correct tooth thickness is important so that all tooth flanks will be completely hobbed during skiving. The allowance of tooth flank stock can be calculated or determined through practical experience. Typically, 0.002\"–0.004\" per flank is used for gears of 12 DP or finer. http://www.geartechnology.com/mag/archive/1102/hard.pdf -------------------------------------------------- Note added at 29 mins (2003-12-16 17:23:14 GMT) -------------------------------------------------- • wälzfräsen=to hob • Wälzfräsmaschine=hobbing machine=hobber • Wälzfrässupport=hobbing carriage • Wälzfräsverfahren=hobbing method http://webcoordinator.de/englisch/dw2.htm . hob cutter=Abwälzfräser • hobbing=Walzfräsen=Abwälzfräsen • hobbing attachment=Wälzeinrichtung • hobbing carriage=Wälzfrässupport • hobbing head=Fräskopf • hobbing machine=Wälzfräsmaschine • hobbing method=Wälzfräsverfahren • hobbing saddle=Fräserschlitten http://branchenportal-deutschland.aus-stade.de/eh4.htm Reference: http://www.imti21.org/documents/taxglossary.pdf |
