Title:
CIRCULAR HOLE MACHINING METHOD AND CIRCULAR HOLE MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/016224
Kind Code:
A1
Abstract:
An out-of-round hole machining device (1), that carries out inner diameter machining for a bore (61, 62, 63, 64) in a cast cylinder block (60) comprises the following: a stress deformation amount correspondence table (406) that stores, for each portion of the cylinder block (60), a stress deformation amount based on stress that resides in the cylinder block (60) during casting; a machining shape prediction section (402) that predicts the machining shape on the basis of the stress deformation amount read from the stress deformation amount correspondence table (406); and a motor control unit (403) that reverses the predicted machining shape with respect to a target shape and carries out reverse machining on a workpiece.
