The invention belongs to the technical field of machining, and particularly relates to a cutter for machining an eccentric shaft recess and a machining method. The effective shape of a cutter head ofthe cutter used for machining the eccentric shaft recess is a non-standard shape, and the cutter comprises a first arc section, a first linear section, a second arc section and a second linear section. By adopting the cutter for machining the eccentric shaft recess and the machining method, cutter grooves of eccentric shaft inner and outer holes can be machined at a time, so that errors caused bymultiple clamping positioning and aligning introducing during turning are reduced, and machining precision is greatly improved. 本发明属于机械加工技术领域，具体涉及一种加工偏心轴空刀的刀具及方法；所述的加工偏心轴空刀的刀具的刀头有效形状为非标准形状，分为：第一圆弧段、第一直线段、第二圆弧段、第二直线段；利用本发明的加工偏心轴空刀的刀具的加工方法，偏心轴内孔和偏心轴外空刀槽一次加工完成，减少了车削多次装夹定位和找正引入的误差，极大提高了加工精度。
