Background
A gear shaper is a metal cutting machine tool, which uses a slotting cutter to machine inner and outer straight and helical cylindrical gears and other tooth parts according to a generating method, and uses the slotting cutter as a cutter to machine the tooth forms of gears, racks and the like, and the machining method is called as 'slotting'.
During gear shaping, a gear shaping cutter performs vertical reciprocating cutting motion and simultaneously performs relative rolling with a workpiece, and a gear shaping machine is divided into a vertical type and a horizontal type, and the vertical type and the horizontal type are most commonly used. The vertical gear shaper has two modes of cutter relieving and workpiece relieving. Cutter back-off is used for high-speed and large-scale gear shaping machines, and workpiece back-off is generally used for medium and small-sized gear shaping machines. On a vertical gear shaper, a gear shaper cutter is arranged on a cutter main shaft and simultaneously performs rotary motion and up-and-down reciprocating slotting motion; the workpiece is mounted on a worktable for rotary motion, and the worktable (or a tool rest) can move transversely to realize radial cutting motion. When the cutter returns, the cutter rest slightly swings backwards to realize cutter relieving movement or the workbench does cutter relieving movement.
