Introduction The formation of drawn automobile cover panel is a type of thin metal sheet forming with multiply non-linear complex processes of mechanics, such as non-linear geometry, non-linear material, non-linear boundary etc.
The final shape of elastic resilience of part is an accumulation of total stamping processes, which is related to many factors such as die geometry, material feature, friction touch etc.
The parts with different materials and sizes have very different resilience law.

Adhesion of workpiece material and chipping are dominant wear mechanisms.
In addition, the existence of high cutting temperature and stress at the cutting edge coupled with the brittleness of tool materials may accelerate the chipping of the inserts [7].

Ambient temperature magnetic refrigeration is emerging as a viable alternative technique to the conventional vapor compression based refrigeration technology by using colossal magnetoresistance (CMR) materials because the former is considered to be more energy efficient and eco-friendly compared to the latter.
This would cause an increase the residual resistivity of the material[27].
