Flocking area intelligent optimization method of flocking broach and broach parametric modeling method

The invention discloses an intelligent optimization method for a flocking area of a flocking broach and a broach parametric modeling method. The optimization method comprises the following steps of: 1, setting an initial flocking area on the front cutter surface of the optimized flocking broach; 2, broaching heat-force coupling simulation is conducted on the basic cutter teeth, and the cutter abrasion distribution condition is obtained; 3, reverse point searching is carried out according to tool abrasion coordinate point data in the tool abrasion cloud picture, and a corresponding cloud picture data file is obtained. And 4, importing the cloud picture data file into curved surface construction software, fitting to obtain a tool wear curve, and constructing a tool wear grid curved surface. And 5, selecting an area corresponding to the tool wear grid curved surface obtained in the step 4 on the front tool surface of the optimized flocking broach as an additional flocking area. And then the union set of the init
