Hard Finishing By Conventional Generating and Form Grinding - March/April 1991
The article "Hard Finishing By Conventional Generating and Form Grinding" appeared in the March/April 1991 issue of Gear Technology.
The quality of a gear and its performance is determined by the following five parameters, which should be specified for each gear: Pitch diameter, involute form, lead accuracy, spacing accuracy, and true axis of rotation. The first four parameters can be measured or charted and have to be within tolerance with respect to the fifth. Pitch diameter, involute, lead, and spacing of a gear can have master gear quality when measured or charted on a testing machine, but the gear might perform badly if the true axis of rotation after installation is no longer the same one used when testing the gear.
