Spin Plan in AASML

The production of compact yarn is 1784lbs/day. So the following spin plan is according to only this production.1.1 Auto ConeWinding rate=900m/minEfficiency=70%Production=winding rate*1.0939*60*8*no. Of spindles*eff.Count*840No of spindles=production* count * 840 Winding rate*1.0936*60*24*eff.=1784*40*840900*1.0936*60*24*0.70=60.41=61No of spindle/frame=61/60=1.02 = 1 framesWaste %age=1%Input=output * 100/100-w=1784*100/99=1802 lb/dayIt is output of ring frame
