OPTIMASI PEMESINAN PEMBUATAN VARIASI TUTUP KATUB SUSPENSI UDARA HONDA GL MAX 125cc DI MESIN TURNING CNC TU-2A (Studi Kasus Kondisi Optimum nt=1 dan nt=500)
Abstract
Optimization is a way to get optimum machinery condition where to
reached optimization condition, usually done with optimizing toward engine
cutting parameter that exist. The aim of optimization is to get cheapest
production cost and lowest production time. In air suspension valve cover
variation making in Honda GL Max 125 cc in turning machine CNC TU-2A
method that done is analytical method with chisel age criteria (T), cutting speed
(v), machine time (tm) and production cost (Cp) in turning machinery process
CNC TU-2A. The result of air suspension valve cover variation making in
Honda GL Max 125 cc in turning machine CNC TU-2A that time required to
completing one product is tc = 3,90 minutes. With optimum condition analysis
between nt = 1 with nt = 500, so obtained calculation result for economic
condition nt = 1, economic production time required tme = 20,69 minutes and
economic production cost Cp,c = Rp. 132.193,04,-/product, productive
production time tm,p = 17,97 minutes, productive production cost Cp,p = Rp.
133.648,69,-/product. For economic condition nt = 500, economic production
time tm,e = 12,74 minutes and economic production cost Cp,e = Rp. 2.175,94,-/
product, productive production time required tm,p = 10,06 minutes, productive
production cost Cp,p = Rp. 3.632,42,-/product.
Keywords : Optimization, cutting speed, chisel age, production time and
production cost.
