describe the gear milling, gear finishing, gear shaving, gear burnishing, roll finishing of gears process, explain the gear lapping and honing process, and understand the grinding of a gear. 6.2 GEAR TERMINOLOGY The gear terminology is explained below with reference to a spur gear which is a particular type of a gear.
Based on the position of hard finishing in the process chain of gear manufacturing, the dominant processes with a geometrically non-defined cutting edge are analysed. While processes like continuous profile grinding and discontinuous generating grinding with double cone discs became less important in the last couple of years, the processes continuous generating gear grinding, discontinuous ...
Like machining processes, the energy used to remove material from the part is concentrated in the part itself, not the abrasive material interfacing with part surfaces, and like many surface-finishing processes material removal is not accomplished by a cutting tool with a single point of contact, but by complete envelopment of the exterior ...
Super Finishing ± 0.003 1 to 10 Different surface finishing processes are described below. Honing Honing is a surface finishing operation based on abrasive action performed by a set of bonded abrasive sticks. It is generally used to finish bores of cylinders of IC engine, hydraulic cylinders, gas barrels, bearings, etc. It can reduce the level of
Gear manufacturing refers to the making of gears.Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking.As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.
Superfinishing, also known as micromachining, microfinishing, and short-stroke honing, is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone or tape; this layer is usually about 1 μm in magnitude. Superfinishing, unlike polishing which produces a mirror ...
