摘要： An indicator that provides information on the wear status of a composite tool that is subject to abrasion during use. The composite tool contains at least one wear groove in the area subject to abrasion. The wear groove has a desired length and predetermined depth. The wear groove is formed of a desired length and of a predetermined depth into the tool in the area subject to abrasion. During use of the tool in composite forming, the tool is inspected for the presence and depth of the wear groove thereby indicating the wear status of the tool.

摘要： An aerodynamic-electrostatic particulate collection system for high-efficiency collection of particulate debris generated in a machining area during machining of a workpiece, especially post-cure machining of a composite workpeice, that includes a vacuum subsystem for generating a localized, vacuum-induced aerodynamic fluid flow field in the machining area and a particulate charging, electric field generating subsystem integrated in combination with the workpiece and the vacuum subsystem for charging particulate debris generated during machining of the workpiece and for creating an electric field that directs the charged particulate debris into the localized, vacuum-induced aerodynamic fluid flow field. The vacuum subsystem includes a vacuum pump, a hose fluidically interconnected to the vacuum pump, and a nozzle fluidically connected to the hose distal the vacuum pump and having a configuration that defines the localized, vacuum-induced aerodynamic fluid flow field. The particulate charging, electric field generating subsystem includes a high voltage power supply, a first conductive lead electrically interconnecting the high voltage power supply and the workpiece, a collection electrode physically integrated in combination with the nozzle, and a second conductive lead electrically interconnecting the high voltage power supply and the collection electrode. The oppositely charged workpiece and collection electrode in combination produce a corona discharge in the machining area that causes the particulate debris generated during machining of the workpiece to be charged. Further, the oppositely charged workpiece and collection electrode in combination create the electric field that is collinear with the localized, vacuum-induced aerodynamic fluid flow field.
