PROBLEM TO BE SOLVED: To facilitate creation of NC data for working a model of a propeller of a ship.;SOLUTION: A propeller NC data creation device is equipped with: a means to input propeller data in which a profile of wings of a propeller is shown and to create a mathematical equation expressing the profile; a means to create wing surface point group data which is point group data in which a surface of the wing is shown based on the mathematical equation; a means to create wing surface angle data which shows an angle in each point of the surface of the wing based on the mathematical equation; and a means to create NC working data to be input into an NC working machine in order to carry out NC working of the wing based on the wing surface point group data and the wing surface angle data.;COPYRIGHT: (C)2008,JPO&INPIT
