$3.$ Calculate the cutting power for Face$-$Mill $\frac{O}{80}mm.12$ Teeth cutting on a Steel Block $80$ mm$.$ Width with depth of cut $0\mathrm{.}6$ mm$.$ Using the cutting tool diagram below for cutting force calculation.

Shear Strength of Steel $=300\frac{N}{m}{m}^2$

Friction Coefficient Carbide $-$ Steel $=0\mathrm{.}4$

Chip Thickness $=0\mathrm{.}2mm.$

Feed use $200m\frac{m}{m}in$

Cutting Speed $=120\frac{m}{m}in$

Find the power of the milling machine that suits to this cutting

condition.

Plan the machining process for this part made from Aluminium Alloy block $756520mm.$ Milling machine has spindle power of $800$ W$.$ Please provide procedures and cutting condition of every step.

The initial stock is $756520mm.$

We have End$-$Mill diameter $5$ mm$.$ and $6$ mm$.(4$ Teeth$)$

Face Mill $6$ Teeth diameter $50$ mm$.$

and Drill diameter $6$ mm$.$
