METHOD OF CORRECTING HUB DATA FOR A CAM WORKING SURFACE AND METHOD OF MACHINING A CAM PROCESSING SURFACE

摘要

In a method of correcting stroke data for a cam processing area, a correction calculating means preliminarily corrects an original lift amount from original lift data such that a rate of change of a machining condition at each machining position on an outer circumferential surface of a cam based on the original lift amount corresponding to the cam rotation angle is equal to or less than a change rate threshold is set in advance, and the correction calculating means corrects the original lift amount corresponding to the cam rotation angle to a finally corrected lift amount based on a preliminary lift deviation which is a deviation between the preliminarily corrected lift amount and the original lift amount at each machining position, a lift deviation threshold, in advance is set, the rate of change of the machining condition and the rate of change location value.
