Provided is a method of controlling a bar supplying apparatus capable of automatically setting a timing of opening a run-out preventing chuck, a timing of cutting a bar short, and a timing of replacing the bar by the minimum input work.A controller 115 of an NC lathe 110 extracts length data (1) of a product and dimensional data (s) of a cutting width from a machining program, calculates the position of a feeder 123 on the basis of those data, and controls supply of a bar W to bar supporting units 128a to 128c, opening/closing of run-out preventing chucks 129a to 129d, and feeding and replacement of the bar W on the basis of the position of the feeder 123. |
