Abstract

Official abstract text for this publication.

Provided is a gear machining method whereby a gear to be machined that is eccentrically mounted can be machined with high accuracy. For this purpose, the gear machining method is such that a target table rotation phase (Co) for a rotation table ( 16 ) and a target cut amount (Xo) for a hob cutter ( 15 ) are set on the basis of data regarding a workpiece (W), that a table rotation phase correction amount (ΔC) is obtained on the basis of an eccentric amount (δ) of the workpiece (W) with respect to the rotation table ( 16 ) and an eccentric rotation phase (φ) of the workpiece (W) with respect to the same, that the rotation table ( 16 ) is rotated in an actual rotation phase (Ct) which is obtained by applying a rotation phase correction amount (ΔC) to the target table rotation phase (Co), that furthermore, a cutting correction amount (ΔX) is obtained on the basis of the workpiece eccentric amount (δ), the workpiece eccentric rotation phase (φ), and the actual table rotation phase (Ct), and that the hob cutter ( 15 ) is made to cut into the workpiece (W) by an actual cut amount (Xh) which is obtained by applying the cutting correction amount (ΔX) to the target cut amount (Xo).

First claim

Opening claim text (preview).

The invention claimed is: 1. A gear machining method of performing gear machining on a work gear by engaging a rotary tool and the work gear with each other and rotating the rotary tool and the work gear in synchronization with each other, characterized in that the method comprises: setting, based on a specification of the work gear, a target table rotation phase of a rotary table configured to rotate the work gear, and a target cutting depth of the rotary tool in the work gear wh…
