This technology provides a method of laserdrilling any component under the control of real-time feedback to provide for predictable, calibrated fluid flow through one or an array of holes formed in the component. The technique can improve flow control through a machined part by an order of magnitude or more over conventional open-loop laser drilling technologies, increasing the predicted lifetime of component parts. The method can be applied to any component or device that requires controlled flow of any fluid.
The technology is accurate to a fraction of one percent of the resulting flow, and can be automated for high-volume production. It is applicable to one or many holes through a single workpiece, and is valid for various fluid types (gas, liquid, plasma) at a wide range of temperatures and pressures.
