摘要： A method for abrasive flow machining includes moving an abrasive media through a high-aspect passage of a workpiece. Local pressure of the abrasive media is increased at target abrasion surfaces of the high-aspect passage using a passage geometry that is configured to direct flow of the abrasive media into the target abrasion surfaces such that the target abrasion surfaces are preferentially polished by the abrasive media over other, non-targeted surfaces of the high-aspect passage at which the flow of the abrasive media is not directed into.

摘要： An apparatus includes first, second, and third layers. The first layer includes a plurality of flanges. The second layer includes a deformable membrane. The second layer is connected to the first layer along a first major surface of the deformable membrane. The third layer is connected to the second layer along a second major surface of the deformable membrane opposite the first major surface. The third layer includes a first series of internal structures.

摘要： A method is provided for additive manufacturing. This method includes monitoring a current to a recoater blade. The monitored current is compared to a predetermined current. An operation is initiated in response to the monitored current exceeding the predetermined current. Another method for additive manufacturing includes comparing a movement of a recoater blade to an expected movement. A single exposure sequence is initiated in response to movement of the recoater blade being different than an expected movement. An additive manufacturing system is also provided which includes a recoated blade and a control. The control is operable to identify resistance to movement of the recoater blade.
