1. A machining system comprising:
- a device operable to emit an energy beam toward a surface of work piece, the energy beam disposed for making a first cut in the surface of the work piece, the energy beam making the first cut in a spiral orientation along the work piece and having a defined space between adjacent spiral sections of the first cut;
a depth measurement system configured to detect real-time cutting depth of the energy beam and provide a feedback signal of said real-time cutting depth; and
a cutting tool disposed adjacent the work piece for making a second cut for removing material from the work piece, the second cut being adjacent to where the energy beam has made makes the first cut in the surface of the work piece, the depth of the first cut made by the energy beam being controlled by adjusting the position of the energy beam with respect to the work piece or the power supplied to the energy beam in response to the feedback signal from the depth measuring system, the depth of the first cut being from about 40% to about 60% of the depth of the second cut that removes material from the work piece, the first cut creating interruptions in the work piece that cause the material removed from the work piece by the cutting tool to break into pieces of a desired length, the size of the defined space determining the desired length of the pieces.

Abstract
A process is disclosed for controlling the length of chips or shavings on materials that is inherent to produce long undesired chips when machined. Based on the work piece configuration and surface area to machine a determined outlay and process application for a continuous scribe or arrangements of different scribe pattern or patterns for the part and or surface is selected to provide optimal chip control during the machining operation. Engineered Interruptions are applied to the work object prior to the machining operation to maximize optimal chip control. Controlling the depth of scribe of the laser is accomplished and managed through the interface of hardware, software and electronics.
