摘要：軸素材の加工取り代を小さくしても、加工後に素材表面が残らないようにする。このセンタ穴加工方法は、第1〜第5ステップを備えている。第1ステップは軸素材の軸方向における複数部位の外周形状データを取得する。第2ステップは、複数の部位の測定データのそれぞれを対応する設計データと比較し、センタ穴決定用の中心軸線を求める。第3ステップは、複数部位において、中心軸線から軸素材外周までの最小距離を算出する。第4ステップは、各部位における最小距離が加工寸法よりも大きい場合には中心軸線が正しいと判断し、最小距離が加工寸法以下の場合には中心軸線を最小距離が加工寸法よりも大きくなる方向に移動し、移動後の中心軸線に基づいて第3ステップを繰り返し実行する。第5ステップは正しいと判断された中心軸線の延長上の軸素材端面にセンタ穴を形成する。

摘要： PROBLEM TO BE SOLVED: To suppress positional shift of a traverser when the travel direction of a wire is inverted.SOLUTION: A wire saw includes a plurality of rollers 14A, 14B for machining where a wire 11 for machining a workpiece is wound around in a stretched state, and traversers 16A, 16B which are moved reciprocally in axial directions of bobbins 12A, 12B to guide the wire 1 to be wound and unwound. As the rollers 14A, 14B for machining and the bobbins 12A, 12B rotate reciprocally, the wire 11 travels reciprocally and a workpiece W is cut with the wire 11 at a position between the rollers 14A, 14B for machining. When the travel direction of the wire 11 is inverted, angles of the wire 11 between the bobbins 12A, 12B and traversers 16A, 16B to axial lines of rotation of the bobbins 12A, 12B are detected. According to detection results, the traversers 16A, 16B are moved and adjusted to correct positions of the traversers 16A, 16B so that the angles of the wire 11 are 90°.
