Abstract
Methods, apparatus, and devices for fluid flushing systems to remove foreign object debris (FOD) are provided. These methods and devices are designed to flush and transport FOD away from machined parts. Foreign object debris refers to any unintended material such as tiny particles, chips that enters a part during a manufacturing process. FOD can have significant effects, compromising the quality and functionality of manufactured items. This can lead to costly consequences such as rework, scrapped parts, and production delays. FOD prevention is essential for improving safety, reliability, and efficiency.
Claims39
A method for preventing foreign object debris in a part finishing operation comprising,
- connecting a part comprising at least one internal channel to a fluid pump such that the fluid pump is in fluid communication with the at least one internal channel;
- operating the pump to pressurize the part with a fluid;
- breaching the internal channel with a machining device to form an opening in the internal channel;
- and
- pumping the fluid through the internal channel and the opening to produce a fluid current that exits the part.
An apparatus for preventing foreign object debris in a part finishing operation, the apparatus comprising:
- a machining device, a fluid, and a fluid pump;
- wherein the machining device is configured to remove material from a part and breach an internal channel of the part to form an opening;
- wherein the fluid pump is in fluid communication with the internal channel and is configured to pump the fluid into the internal channel, and pressurize the part with the fluid;
- wherein the fluid pump is further configured to circulate the fluid through the internal channel and the opening;
- and
- wherein the fluid is configured to transport foreign object debris.
A device comprising,
- a cylindrical base with a central axis, a first end with an exit hole therewithin, and an exterior coaxial with the central axis and with an entrance hole therewithin;
- wherein the entrance hole and the exit hole form a fluid path.
- a housing disposed about the cylindrical base with a cylindrical interior coaxial with the central axis, and an exterior with a through hole therewithin;
- a first bearing and a second bearing coaxial with the axis,
- wherein the first and second bearings are disposed about the base, distal to the through hole and on opposing sides of the through hole;
- and
- wherein the first and second bearings are coupled to the base and the housing and configured so that the housing can rotate about the base and form a fluid path such that the through hole and the exit hole are in fluid communication.
