Treatment apparatus, machining system central holes, program for deciding the position of center holes, and method to say the position of center holes

摘要

Processing apparatus for deciding a position of center holes to be made in a physical crankshaft (1), comprising: means (20b) data acquisition of three-dimensional shapes to acquire data of three-dimensional shapes of the physical crankshaft (1); and means (20c) assuming the position of the center hole to assume the position of the center hole in the physical crankshaft (1) based on data of three-dimensional shapes; characterized by means (20d) specification shapes to simulate a predetermined machining for physical crankshaft (1) based on the assumed position of the center hole as a reference, and then specifying a shape of the physical crankshaft (1) after the machining simulation ; means (20f) resolution balanced to decide whether a magnitude of rotational imbalance in the crankshaft physical form (1) after the machining simulation is within a predetermined allowable range; and means (20g) for determining the center hole for deciding the assumed position of the center hole as drilling actual position of the center hole when the rotational imbalance magnitude is within the predetermined allowable range.
