A Fem Analysis to Determine Effect of Milling Parameters on Plastic Strain and Plastic Strain–Rate Distribution When Milling Hastelloy C-22HS.

The Finite Element Method and Response Surface Method are used to find the effect of milling parameters (Cutting speed, Feedrate and Axial depth) on plastic strain when milling Hastelloy C-22HS. This simulation gain more understanding of the strain distribution in metal cutting. Response surface method (RSM) has been used to minimize the number of simulation. The contour plot from the RSM shows the relationship between variables (cutting speed, feedrate and axial depth) and response (plastic strain - rate). The friction interaction along the tool-chip interface is modeled with Coulomb friction law. [ABSTRACT FROM AUTHOR]
