The present invention discloses an automatic high-shear low-pressure force-controlled grinding device for a complicated curved surface and a machining method thereof, which belong to the field of complicated curved surface grinding technologies of difficult-to-machine materials. The device comprises a base, columns, an industrial robot, an electrical spindle, a force-controlled floating tool holder, a workpiece chuck, a grinder plate, a six-dimensional force sensor, a rotary table, a triaxial precision displacement table, a safeguard hood, a safety door, and a pedestal. The grinder plate comprises a grinder plate substrate, a press plate, a lining plate, and an abrasive layer. Each module is effectively communicated, and a control system collects and processes signals as well as transmits commands to achieve automatic force-controlled grinding of the complicated curved surface. The abrasive layer of the grinder plate generates the shear thickening effect; so, the material can be removed in a high-shear low-pressure grinding manner. 1.
