Abstract
A method for cutting an internal feature in a workpiece using a plasma cutting system can include cutting in a first zone using at least one cutting parameter from a first cutting parameter set, which can include a first cutting current and/or a first speed. The method can include cutting in a second zone using at least one cutting parameter from a second cutting parameter set that can be different from the first cutting parameter set. The second cutting parameter set can include a second cutting current and/or a second speed. The method can also include cutting in a third zone using at least one cutting parameter from a third cutting parameter set, which can be different from the first cutting parameter set or the second cutting parameter set. The third cutting parameter set can include a third cutting current and/or a third speed.
