  • Servo stroking method and system for producing special shapes
    Patent number: 8348718
    Abstract: A servo stroking method and system for honing wherein the cam stroking motion is controlled via combined acceleration and deceleration cam profiles to produce a finite jerk profile, a precision positioning capability for the honing element or elements, and accurate position feedback. The stroking motion is synchronized with one or more other parameters of the honing operation, such as the feed or rotational position of the honing tool, for generating non-cylindrical and special honed shapes such as tapered, barrel, and helical shapes. The cam profile can be selected for example from a simple harmonic 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.
