Zusammenfassung:	To form a processing trace on a circular-arc surface of a circular arc-shaped cross-section toward the center of a curvature of the circular-arc surface.SOLUTION: A processing device includes: a chuck table on which a workpiece 200 is fixed; a processing unit for forming a cutting groove in the workpiece 200 fixed to the chuck table; a processing feed unit for moving the chuck table 10 in an X-direction; an indexing feed unit for moving the processing unit in a Y-direction; a cutting-in feed unit for cutting-in and feeding the processing unit in a Z-direction; and a control unit. The chuck table has a fixing part 12 to which the workpiece 200 exposing the circular-arc surface 201 is fixed with an X-direction axis 131 as an axis of rotation. The control unit rotates the fixing part 12 after forming a cutting groove in the circular-arc surface 201 of the workpiece 200 with a ridge of the circular-arc surface 201 fixed to the fixing part 12 along the X-direction.SELECTED DRAWING: Figure 3 【課題】断面円弧状の円弧面に円弧面の曲率の中心に向かって加工痕を形成することができること。【解決手段】加工装置は、被加工物２００を固定するチャックテーブルと、チャックテーブルに固定された被加工物２００に切削溝を形成する加工ユニットと、Ｘ方向にチャックテーブル１０を移動させる加工送りユニットと、Ｙ方向に加工ユニットを移動させる割り出し送りユニットと、加工ユニットをＺ方向に切り込み送りさせる切り込み送りユニットと、制御ユニットと、を備える。チャックテーブルは、円弧面２０１を露出した被加工物２００が、Ｘ方向の軸心１３１を回転軸として回転可能に固定される固定部１２を有し、制御ユニットは、円弧面２０１の尾根がＸ方向に沿って固定部１２に固定された被加工物２００の円弧面２０１に、切削溝を形成した後、固定部１２を回転させる。【選択図】図３
