DEBURRING/EDGE FINISHING METHOD AND DEBURRING/EDGE FINISHING APPARATUS

To provide a deburring/edge finishing method and a deburring/edge finishing apparatus capable of expanding the range of gear shapes that are formed on a to-be machined object, without using an eddy current sensor and by eliminating interference between a tool and a workpiece or fixture.SOLUTION: Provided is a deburring/edge finishing method for deburring or chamfering an edge of a gear-shaped workpiece 150 using a tool, including relatively rotating at least one of the workpiece 150 and the tool 136 to machine the tip of at least one tooth for determining whether the workpiece 150 and the tool 136 are in contact, estimating the phase of the workpiece 150 on the basis of the contact state between the workpiece 150 and the tool 136, and making the tool 136 follow the edge of the workpiece 150 on the basis of the estimated phase of the workpiece 150.SELECTED DRAWING: Figure 1 【課題】渦電流センサを使用することなく、ツールとワークや固定治具との干渉をなくして、加工対象にできる歯車形状の範囲を拡大することが可能なバリ取り／エッジ仕上げ方法およびその装置を提供する。【解決手段】ツールを用いて歯車形状のワーク１５０のバリを除去する、またはワーク１５０のエッジを面取りするバリ取り／エッジ仕上げ方法であって、ワーク１５０またはツール１３６の少なくとも一方を相対的に回転させて少なくとも１歯の歯先を加工し、ワーク１５０とツール１３６が接触しているか否かを判定し、ワーク１５０とツール１３６の接触状態からワーク１５０の位相を推定し、推定したワーク１５０の位相に基づいて、ワーク１５０のエッジに沿ってツール１３６を倣わせる。【選択図】図１
