Time for <strong>Drilling</strong>:<br />
EXAMPLES<br />
Length of tool travel = Length of hole +<br />
Length of clearance<br />
= 100 + 20<br />
<br />
= 120 mm<br />
Tdrilling = L/(f×N)<br />
= 120/(0.5×200)<br />
<br />
= 1.2 minutes<br />
<br />
Total time:<br />
Total processing time/component = Tfacing +<br />
Tturning + Tdrilling<br />
= 1.2 + 1.6 + 1.2<br />
<br />
= 4 minutes.
