In accordance with the latest development direction in the filed of strengthening the heat transfer technology of strengthening the heat transfer on division of strengthening heat transfer by international authoritative Professor A.E. Bergle）, including 3D(three-dimensional) heat transfer of ultra-high performance improved in the fins of the design and analysis; 3D heat transfer strengthening of the plowing process mechanism the flexibility ,high speed and high precision of gathered tools and the realization of a 3D digital design and manufacturing . It also researches on the influential law of process parameters on the formation of the fin. It is shown that the whole fin-forming process can be classified into three stages：plowing，heaving and fins forming, and that the front angle，plowing depth and the plowing speed are the main factors influencing the fin forming. Moreover，within a certain range，the height of fin increases with the front angle and the plowing depth.
