$MRR$ culculation in AJM

$(dg)=$ mean diamelet of $1h_e$ hemisphenial abrasive

$A{B}^2=A{C}^2+B{C}^2$

$B{C}^2=A{B}^2-A{C}^2$

$=(\frac{dg}{2}{)}^2-(\frac{dg}{2}-{)}^2$

$=(\frac{ds}{2}{)}^2-[(\frac{dg}{2}{)}^2+{}^2-2\frac{dg}{2}]$

$=\frac{dg}{r}*-{}^2$

$B{C}^2+{}^2=dg..$

Ignary ${}^2[{}^{2}0]$

$B{C}^2=(dz.)$

:$.BC=\sqrt[\phantom{2}]{d_y}=r$

Now son the nemisphere vhan $gra{d}_B=$

$gra{d}_B=\frac{2}{3}{r}^3=\frac{2}{3}(d_g{)}^{\frac{3}{2}}$

$N{N}^0,k*E=\frac{1}{2}m*v^2$

$Nm=s_3*gra{d}_{}*$

:$.h*E=\frac{1}{2}*({}_g*gra{d}_B)v^2$
