Procedural:
1.Cari D-eks dengan rumus
D= log(R/60*N)/log(12*W/10^6*Dpa)
Ket:
D=d-eks
R=laju penembusan,ft/hr
N=Putaran,RPM
W=berat pahat bor,lbs
Dpa=diameter Pahat,inch
2.Cari d-corr denagan rumus
D corr= densitas normal/densitas nyata
Densitas normal=9ppg
3.Plot d corr vs depth,cari persaman garis dengan 2 data d corr
vs depth
Diperoleh: y = 20067x - 20086
