Abstract: A component machining apparatus includes a measurement result acquiring unit and a machining data generator. The measurement result acquiring unit is configured to acquire a measurement result obtained by a measurer configured to measure a three-dimensional shape of a manufactured component among components of a structure. The manufactured component is manufactured earlier than a component of interest. The machining data generator is configured to generate machining data of the component of interest based on the measurement result of the manufactured component that has been acquired by the measurement result acquiring unit.

Abstract: A manufacturing assistance apparatus includes a learning unit and an estimator. The learning unit is configured to load a plurality of pieces of actual measurement data in each of which a gap and a plurality of parameters are associated with each other, and construct an estimation model on the basis of machine learning in which the plurality of pieces of actual measurement data serve as teacher data. The gap is provided between a first workpiece and a second workpiece that eventually structure an airframe of an aircraft and that are eventually fastened to each other. The estimation model estimates the gap from the plurality of parameters. The estimator is configured to derive an estimation value of a length of the gap on which measurement has not yet been performed, on the basis of the estimation model constructed by the learning unit and the plurality of parameters.
