Abstract
A method and apparatus is presented. A structure having an interior channel is formed using additive manufacturing equipment. A viscous media containing abrasive particles is sent through the interior channel using abrasive flow machining equipment to form a desired surface roughness for the interior channel.
Claims13
A method of manufacturing a part comprising:
- sintering additive layers to form a structure having complex channels, wherein the complex channels comprise multiple perpendicular angles;
- holding the structure in an abrasive flow machining workpiece, wherein the structure has the same shape as the abrasive flow machining workpiece;
- and
- sending a viscous media containing abrasive particles through the complex channels using the abrasive flow machining workpiece to form a desired surface roughness for the complex channels.
