Systems and methods are provided for fabrication of frames for aircraft. One such method for fabricating a frame (150) for an aircraft (10) comprising receiving a frame (150) comprising a web (564), a shear tie foot (562), and sacrificial material (554) that increases a thickness of the shear tie foot (562); machining the shear tie foot (562) to a thickness that, in combination with a thickness of a skin (50), corresponds with a grip length of a fastener (510); placing the shear tie foot (562) against an inner mold line of the skin (50); and installing the fastener (510) through the skin (50) and the frame (150) to fasten the frame (150). One such system for fabricating a frame (150) of an aircraft (10), the system comprising an array (160) of stations that are arranged in an arc corresponding to a shape of a frame (150), comprising a machining station (120, 122) that removes sacrificial material (554) from the frame (150); and a drive unit (102) that advances the frame (150) through the stations.
