Patent ID: 8186199

Claim:
A method of forming a tubular slip assembly comprising the steps of forming a plurality of first splines on a first spline member with a first feed rate, the first spline member being a female spline member; forming a first spline section and a second spline section on a second spline member, the first spline section and the second spline section each having a plurality of splines formed with a second feed rate, the second spline member being a male spline member; forming a relief zone onto the second spline member, wherein the relief zone is formed with a third feed rate and is formed between the first spline section and the second spline section; and cooperatively engaging the first spline member with the second spline member such that the first spline member concurrently rotates with the second spline member, the first spline member further axially moveable relative to the second spline member, and the relief zone defining a clearance fit relative to the first spline member.
