1. A determination apparatus comprising circuitry configured to:
receive operation information corresponding to an action being performed by a machine to be diagnosed and a detection signal of a physical quantity that changes according to the action of the machine;
take out, from the detection signal, an operation detection signal indicating that the machine is operating, based on the operation information;
extract feature information of the operation detection signal;
select, from the feature information, particular feature information to be compared with a plurality of reference feature information; and
determine a machining section of the machine in the feature information, based on the plurality of reference feature information and the particular feature information, wherein the machine is configured to perform an action including an outward movement and a return movement, and
wherein the circuitry is configured to perform a process of combining the operation information acquired in the outward movement with the operation information acquired in the return movement based on a determination that (a) a time from a stop of acquisition of the operation information of the outward movement to a start of acquisition of the operation information of the return movement is equal to or shorter than a threshold time and (b) the machine is in a predetermined operating state.
