This machine tool is provided with an arithmetic control unit that: controls a motor so as to measure the positions of raw material holes in a boom using an imaging camera held on a main shaft (S111-S113); calculates the positions of the center axes of the raw material holes on the basis of the information about the positions of the raw material holes captured by the imaging cameras (S114, S115); calculates distances between two center axes of interest (S116); and, when at least one of the calculated distances does not meet a prescribed value (S117), calculates the most suitable positions for process holes from minimum holes that comply with formulae (1111-1) to (1114-1) and (1141-1) to (1144-1) on the basis of equations (1101), (1111) to (1114), and (1141) to (1144) (S121); and controls the motor so as to form process holes in the positions calculated as the most suitable and cuts raw material holes using a tool held on the main shaft (S122, S123).
