The invention discloses a cutting performance prediction method of a flocking broach. The method comprises the following steps of: 1, acquiring the effective contact length of a broach to be tested in a cutting process; and 2, acquiring a transduction coefficient for evaluating the heat dissipation capability of the tested broach. And 3, judging the broaching performance of the tested broach. According to the method, various parameters of the flock on the rake face of the broach and factor parameters of the lubricating liquid are considered, the temperature field mathematical model of the flocking broach is constructed, and accurate evaluation of the temperature field in the cutting process of the flocking broach is achieved through the transduction coefficient. By constructing the two mathematical models, the effective contact length and the transduction coefficient of the flocking broach can be accurately obtained, the cutting performance of the flocking broach is evaluated according to the effective contac
