About the Profile Constancy by Curved Teeth Cylindrical Gear’s Cutter Head

Open access


Cylindrical gears with Archimedean spiral toothline represent a result of recent research. Similarly to the Öerlikon type bevel gears this type of gears cannot be grinded. This fact leads to the necessity of achieving best possible surface roughness while cutting using a specific cutter head. The paper presents the geometric model of the grinding technology applied for the main relief faces of the cutters and analyses the problems regarding the precision of the edge profile, its dependence with the technological setting parameters and the profile variation after the re-sharpenings. It concludes that the classic method of ground grinding allows a restricted number of resharpenings.
