The invention relates to the technical field of crystal processing, in particular to an irregular folding method and system for a tuning fork wafer, and the folding method comprises the following steps: obtaining the coordinate data of an original wafer, and building a rectangular coordinate system according to the coordinate data; modifying an index and a use state of the coordinate data corresponding to the fixed frame position; extracting coordinate data with the same longitudinal coordinates in the rectangular coordinate system to form a tree-shaped data structure, and marking child nodes for coordinate data corresponding to each tuning fork wafer in the tree-shaped data structure; folding knife information in a folding knife mechanism is obtained, the use condition of a folding knife is analyzed according to the tree-shaped data structure, the child nodes and the folding knife information, and a folding path of the folding knife is determined according to the use condition of the folding knife; and contr
