The invention discloses a method for evaluating the maximum allowable fillet radius of a grinding wheel for grinding a chip flute of an integral cutter, which can provide reference for selection of the fillet radius of the grinding wheel and comprises the following steps of: projecting a core thickness revolution surface of the chip flute into the section of a grinding wheel shaft on the basis of an arc projection principle; the grinding wheel fillet radius is adjusted so that the circle where the adjusted grinding wheel fillet is located can be tangent to the upper envelope line of the arc projection of the core thickness rotation face, and therefore the tangent contact fillet radius is determined, and the grinding wheel fillet radius optimization model is established with the maximum tangent contact fillet radius as the optimization target. According to the method, the end section profile of the chip flute of the cutter does not need to be predicted during each iteration, the model solving speed is high, an
