The system will use this file name for NC data output. You can type a customized name. You can also click the Comments button located under the Tool Path Name text box to type the Machine Strategy Comments.
◦ Feature Name—The name of the feature being machined. This name is displayed for information purposes only; you cannot change it. You can click the Preview button located under the Feature Name text box to highlight the feature geometry.
