Guys I know this is a PLC website and iam asking general questions.. Please excuse me. I am trying to figure out the drill time required on a plate which has multiple rows of holes to drill and tap.
1.Drill(ft)=No Of Holes*(Thickness Of Sheet))/12
2.Drill(ft/min)=Spindle r.p.m (rev/min)*Feed(inches/rev))/12
3.Drill Time(hrs)=((Drill Ft / Drill Ft/min)/60)
Is this right? if not how and if it requires tapping then same formula should apply correct? Your advise will be appreciated.
