A $22$ mm diameter hole is made in $30$ mm thick solid block using $20$ mm diameter drill and boring tool. The

twist drill related angles are: helix angle $=22,$ point angle $=118,$ and chisel angle $=130.$ The selected cutting velocity

and feed are $20\frac{m}{m}in$ and $0\mathrm{.}1m\frac{m}{r}ev,$ respectively for both the operations. The measured cutting and thrust forces

are $600$ N and $200$ N $,$ respectively. Find $($I$)$ Maximum and minimum rake angle of the drill $($II$)$ Time required for

making through hole taking approach and over travel length as $3$ mm each $($III$)$ Time required for making blind hole

up to $20$ mm depth $($V$)$ Upward thrust and Torque on the drill.Please give handwritten solution
