Abstract

The TU-2A CNC machine is a turning machine tool that is controlled by a computer system through data (program input) in the form of letters and numbers. This machine is capable of producing a work piece with a complex shape and high accuracy, as well as the effectiveness of minimum production time. Gas stove nozzle is a form of work piece which in the manufacturing process is required to have a high level of effectiveness with high accuracy. The supporting factors in the manufacturing process are based on the selection of program functions and machining parameters (cutting speed, feeding, feeding speed and proper rotation of the main axis).In the process of making gas stove nozzles using a CNC TU – 2A machine, the parameter values used are cutting speed (Vs) 20 m/min, feeding 0.75 mm/put, feeding speed (s') 281 mm /min and the main axis rotation (n) 375 rpm.So from the parameters used, it is known that the total machining time per component (tm) = 5.4 minutes, the total production cost per component (Cprod) = Rp. 8,572, - and the total production time per component (t prod) = 7.6 minutes. The greater the value of the Dept of cut, feed and feeding speed, the production time and production costs that occur will decrease until they reach t = 2.6% and C = 2.3%.

Abstract

Needs consumer will tool transportation train fast fire on time now has sue Railway Corporation for Upgrade service and comfort for satisfaction para para consumer use tool transportation this in activity everyday. Look importance needs consumer will comfort use tool transportation train fire, then Writer interested for discuss comfort in journey train specifically problem journey train fire with elevation rail  in pass Bend moment drove. Analysis done from Railway Corporation with literature assistance regarding problem railway. Remember breadth existing problems on train fire, then Writer limit only on calculation point heavy carriage, the forces that occur, and balance carriage when turn without and existence rail elevation. From result analysis carried out elevation data is taken rail maximum by 110 mm, radius curvature, speed plan maximum 120 km/h. Generate speed data critical in bend without elevation rail, and speed critical in bend existence rail elevation.
