Servo stroking apparatus and system

A honing machine comprising:

• a honing element movable in a reciprocating stroking motion for honing a work piece;
• a servo in connection with the honing element controllably operable for reciprocally moving the honing element in the stroking motion;
• a servo drive in connection with the servo operable for controllably operating the servo;
• and
• a control in connection with the servo drive for operating the servo drive to control the servo for axially reciprocally stroking the honing element, such that during at least a portion of the reciprocal motion acceleration and deceleration of the honing element will have a profile selected from a group consisting of a cycloidal profile, a modified trapezoidal profile, a polynomial profile, and a modified sine profile, such that a resulting jerk profile of the reciprocal motion will be finite.

A method of honing comprising steps of:

• providing a honing machine including structure supporting a honing tool so as to be movable in a reciprocating linear motion while the honing tool is rotated, for honing a work piece;
• providing a servo in connection with the honing element controllably operable for reciprocally moving the honing element;
• and
• controllably operating the servo for linearly reciprocally stroking the honing element, such that during at least a portion of the reciprocal motion acceleration of the honing element will have a profile comprising a mixture of at least two of a simplified harmonic profile a cycloidal profile, a modified trapezoidal profile, a polynomial profile, and a modified sine profile, such that a resulting jerk profile of the reciprocal motion will be finite.
