Background
Eccentric inclined hole machining refers to that the axis of an eccentric inner hole of a workpiece is inclined at a certain angle with the axis of a main shaft of a machine tool, and is generally easy to realize on five-axis equipment, but parts which are machined by the inner hole of the eccentric inclined hole in a segmented mode twice are difficult to machine. The two sections of inner holes on the same inclined axis of the eccentric inclined hole are clamped and processed twice, and mainly the control of the degree of freedom of the inclined axis of the two times of clamping and processing along the direction of the coordinate axis of the eccentric inclined hole of the workpiece is difficult to control, namely, how to control the inclination direction of the processed eccentric inclined hole axis on the position of the workpiece. The design of the two-time processing of the inner hole section of the eccentric inclined hole is rarely encountered in the design and processing of parts at ordinary times. The positioning accuracy of the parts which are processed twice by the inner hole of the eccentric inclined hole in a segmented way is higher.
