Tool Path Generation for 5-axis Laser Direct Manufacturing and Re-manufacturing

The paper introduces the construction features of undevelopable ruled surface integral impeller and two 5-Axis numerical control mill machining methods of vane shape which are "line contact" (flank milling) and "point contact".

Two correlation functions containing cluster property of Li atom,e -α(r 1+r 2)-βr 3 and i(2-αr i)e α2r ie -αjr j(1i,j3),were respectively introduced into the hyperspherical coordinate method,and Schr*iedinger equation of Li ground state was primarily solved by the two methods.
