Materials and experimental procedure Table 1 Chemical composition of tested steel wt% C Mn Si Cu Al Ni Cr P 0.027-0.07 0.14-1.433 ≦0.405 0.018-0.328 ≦0.0782 0.007-0294 0.01-0.47 ≦0.01 The tested steel was obtained from the CSP line of Wuhan Iron and Steel (Group) Corporation with chemical composition shown in Table 1. a serious rolling piece at different stands (F1-F7) was obtained by suddenly stopping the CSP line when seven-stand was just finished during its production of the steel, and specimens were cut from it after each pass of the same rolling piece.
The alloying elements mainly include C, Mn, Si, Cr, Ni, Cu, P and Al(those whose amount less than 0.01% were ignored).
Consequently,the connection of the structure and the yield strength(YS), the tensile strength(TS) and the elongtaion (EL) of Q235B can be described as follows[7]： YS=514.66+484.26[C]+55.01[Mn]+221.49[Si]+150.13[Cu]+86.64[Al]-132.21[Ni]+12.82[Cr] +206.78[P]-9553.53XFd-1/2-1.16XP (8) TS=574.38+670.43[C]+67.94[Mn]+225.48[Si]+153.41[Cu]+23.31[Al]-131.47[Ni]+70.37[Cr] +232.36[P]+389.53XFd-1/2-2537.19XP (9) EL=68.83-34.30[C]-1.62[Mn]-12.86[Si]-9.58[Cu]+5.85[Al]+6.48[Ni]+4.85[Cr]-27.11[P]-20.6 3XFd-1/2-262.41XP (10) where XF, XP are the volume fraction of ferrite and perlite,respectively; d is the size of ferrite.

Shirase el al[1] studied the cutting force and machining error of thin-wall part machining with tool with changeable angle between tooth.
Ratchev et al[4,5] also bulit the flexible prediction of cutting deformation and surface error of tihn-wall part by finite element method.
Tang et al[6] built the theorical model of elastic tool recession error in the milling process of thin-wall part.
Wan el al[7] built the prediction model of finished surface static error of thin-wall part based on the thoerical cutting force model and the change density idea of topology optimation design.
Li et al[9] built the analyze and calculation model of thin-wall part machining deformation based on ANSYS.
