SERVO STROKING APPARATUS AND SYSTEM

摘要

A servo stroking apparatus and system for honing wherein the cam stroking motion follows a cam profile which produces a finite jerk profile for reducing machine vibration and optimizing one or more honing parameters. The cam profile can be selected for example from a simple harmonic cam profile, a cycloidal profile, a modified trapezoidal profile, a polynomial profile, and a modified sine profile, or a mix of cam profiles. The servo controlled stroker mechanism can include for instance a ball screw mechanism, a linear motor, a fluid cylinder, a chain drive or a belt drive. One or more other servo controlled aspects of the honing operation can be synchronized with the servo controlled stroking operation, such as the rotation of the honing tool.
