<p><P>PROBLEM TO BE SOLVED: To provide a machining diameter correction device that can proceed a hole drilling while feed-backing that a correction of a machining diameter is executed appropriately wherein a configuration of the machining diameter correction device is improved to be simpler so that automation of the hole drilling at the machining diameter is advanced. <P>SOLUTION: The machining diameter correction device 1 to correct a machining diameter A processed by a tip 9 at boring includes: an input unit 11 which is a portion displaced by pressing; an output unit 12 which is displaced by a predetermined stroke S due to a displacement of the input unit 11 by a predetermined stroke L; and a converting mechanism 16 which converts the displacement of the input unit 11 to the displacement of the output unit 12. The device also includes: a pressure sensor 3b which measures a suppress strength F toward the input unit 11; and a controlling unit 4 which preliminarily stores information related to an acceptable value of the suppress strength F towards the input unit 11 and determines whether the suppress strength F measured by the pressure sensor 3b conforms to the acceptable value. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
