METHOD FOR DETERMINATION OF LONGITUDINAL AND PROFILE MODIFICATION OF TOOL GEAR TOOTH SURFACE

摘要

A method for determination of longitudinal and profile modification of tool gear tooth (I) which linearly meshes with a gear to be machined, wherein modification parameters are determined from the following relationship: <IMAGE> where: delta -the amount of modification of the tool gear tooth (I) in a direction perpendicular to a radius r identifying the location of a contact point on a machining surface (5) relative to a centre (O) of rotation of the tool gear; p-the requisite change in the normal component of the cutting force; G-the rigidity of an arrangement providing for synchronous rotation of the gear blank and the tool gear as reduced to the tool gear axis.
