Chamfering and deburring have been described as "unloved," a "necessary evil" and, in fact - "dead." After all, manual deburring is still common in many shops.
This article presents an analysis of asymmetric tooth gears considering the effective contact ratio that is also affected by bending and contact tooth deflections. The goal is to find an optimal solution for high performance gear drives, which would combine high load capacity and efficiency, as well as low transmission error (which affects gear noise and vibration).
Excessive machine tool vibration during a precision grinding operation can result in poor workpiece quality in the form of chatter, rough finishes, burn, etc. One possible reason for
excessive vibration is directly associated with the relationship
between natural frequencies of a machine tool system and the
operating speed of the grinding wheel spindle.
