CONTROL DEVICE FOR MACHINING CONNECTING ROD, METHOD FOR MACHINING CONNECTING ROD, AND PROGRAM FOR MACHINING CONNECTING ROD

摘要

PROBLEM TO BE SOLVED: To provide a technology for more efficient machining of a connecting rod while a true roundness of a connecting rod penetration part thereof is still maintained.

SOLUTION: A research for the relation between an inner diameter of the connecting rod penetration part at a specific portion and a control parameter of a machining device suitable for a true roundness of the penetration part is carried out in advance, and a relevant data table is stored in a database 201. The control parameter is acquired by cross-checking a measurement value of the inner diameter measured at the specific portion when machining the connecting rod, with the data table stored in the database 201. This therefore allows the connecting rod penetration part with a true roundness to be machined without measuring diameters of a plurality of points.
