Differentiate Between Gear Hobbing And Gear Shaping With Reference To Various Relative Motions And Applications? |
|
Answer» Gear hobbing is a continuous indexing process in which both cutting tool (a hob) and WORK piece rotate in a constant relationship while the hob is being fed into work. Hob is ALSO imparted a radial feed. Gear shaping USES a pinion type of cutter which is reciprocated with REQUIRED cutting speed along the face of workpiece and is gradually fed RADIALLY to plunge. Continuous generation motion is obtained by feeding cutter to full depth and rotating the cutter and workpiece slowly.
