Abstract：
|
|
With the rapid increase of market demand for micro parts,micro bending formation plays an important role in the fabrication of micro products.However,the influence of scale effect makes the micro forming into a totally new research field.After introducing the basic theory of scale effect,grain size and friction in the field of micro bending during the past ten years,its development in forming means,workpiece die material,forming system,numerical simulation and forming precision were discussed.Furthermore,a micro bending system with the laser-aided heating was presented,in which the piezoelectric ceramic was used for driver and micro bending die was made of ceramic fiber.
