TREATING APPARATUS, CENTER-HOLE WORKING SYSTEM, A COMPUTER-READABLE RECRDING MEDIUM RECODING THEREON A CENTER-HOLE POSITION DECIDING PROGRAM, AND CENTER-HOLE POSITION DECIDING METHOD

摘要

invention processing unit, center hole machining system, the center hole of the positioning program, and the center of the ball relates to a positioning method, facilitating the location of the center hole (center-hole) of the crankshaft (crankshaft), and provides a technique that can be determined appropriately. The processing apparatus includes a three-dimensional shape data acquiring means, center hole passed forward means, shape specifying means and, balance deciding means and center includes a ball confirmation means. Three-dimensional shape data acquiring means acquires three-dimensional shape data of the material crankshaft. Center hole passed forward means assumes the position of the center hole of the material crankshaft based on the three-dimensional shape data. Shape specifying means is, assuming ( ) the center machining simulation for the material crankshaft based on the position of the ball (simulation) to, and specifies the shape of the material crankshaft after the working simulation. Balance determination means determines whether or not within the allowable range of the predetermined rotational imbalance amount in the shape of the material crankshaft after the working simulation. Center ball confirmation means, when the rotational imbalance amount is within the predetermined allowable range, and determines the position of the home position of the center hole as a center hole of the actual processing.
