Abstract

Product quality of a production process can not be separated from several other factors, including the planning and machining processes, which take place during the machining process there is interaction between the chisel work with the workpiece, the workpiece is cut off and the chisel work experience friction. As a result of this friction chisel wear out. Tool wear will be enlarged to a certain extent so that the cutting tool can not be used anymore. The length of time to reach the wear limit is defined as the tool life. Data on tool life is greatly needed in the planning process of machining a product. This study aims to determine the price constants (CT) and exponent (n) Taylor tool life equation in Turning Process with carbide Sculpture and Objects Work St 42, St 60 and Iron Castings and to determine the relationship between the input variables and the response variable from the observed process .The method used to determine the constants and exponents Equation Age Sculpture Taylor is a statistical method, while the statistical method is selected Linear regression analysis method to the calculation method of least squares or Least Squares Method. The study was conducted by observing the cutting conditions, where the cutting speed is varied the cutting speed ; v (m / min) selected three levels of cutting speed (v) is v1 = 37.68 m / min, v2 = 36.11 m / min, v3 = 34.54 m / min. Motion feeding also varied; f (mm / output) while eating the selected motion refers to the ability of the chisel is used and specification capabilities of the machine, the greater the speed selected eat, f1 = 0.25 mm / r and; f2 = 0.30 mm / r. Depth of Cut ; A (mm) made constant. Depth of cut selected; a = 1 mm.Getting research results, for the material St. 42 with f = 0.25 mm / put in can be CT = 65.92, n = 0.1737 are for f = 0.3 mm / put in can be CT = 72.4, n = 0.217. For Material St.60 with f = 0.25 mm / put in can CT = 57.5 n = 0.1482 are for f = 0.3 mm / put in can be CT = 47.68 n = 0.107. For material Iron Castings with f = 0.25 mm can be CT = 45.6 n = 0.107 are for f = 0.3 mm can be CT = 44.175 n = 0,103. The increase in cutting speed (v) is proportional to the occurrence of edge wear (VB). And at the same pace of growth will increase the wear edge is proportional to the time of cutting. The addition of the cutting speed and depth of cut motion meal will still result in the increase of the chisel edge wear so that tool life will decrease.

Abstract

Perkembangan ilmu pengetahuan dan teknologi telah mendorong manusia untuk menciptakan teknologi yang semakin maju. Diantara teknologi tersebut adalah pengembangan mesin kendaraan dengan sistem bahan bakar injeksi (EFI), mesin dengan sistem ini mensyaratkan penggunaan bahan bakar tanpa timbal (pertamax plus), namun kenyataannya bahan bakar dengan jenis pertamax plus sangat sulit untuk ditemukan khususnya untuk daerah perkampungan, sehingga kebanyakan masyarakat masih menggunakan bahan bakar bensin (premium). Penggunaan bahan bakar premium ini menghasilkan gas buang yang berbahaya yaitu karbon monoksida (CO) dan hidro karbon (HC) yang dihasilkan dari proses pembakaran.Berdasarkan latar belakang tersebut maka dilakukan penelitian terhadap sepeda motor sistem EFI empat langkah 150 cc dengan menggunakan bahan bakar premium pada putaran 2000, 2500 dan 3000 rpm. Tujuan penelitian ini dilakukan untuk mengetahui emisi gas buang dan temperatur oli pada sepeda motor sistem EFI.Dari hasil penelitian disimpulkan bahwa penggunaan premium pada sepeda motor sistem EFI menghasilkan CO tertinggi dengan nilai 3,04%, HC tertinggi dengan nilai 63 ppm dan temperatur oli mesin tertinggi pada 86 0C. Dengan demikian penggunaan premium pada sepeda motor sistem EFI dinyatakan aman untuk digunakan.

Abstract

The study focused on analyzing the failure of the sun gear section of the swing drive excavator, where there has been a failure in operation. The gears are predominantly damaged in certain areas while other areas appear to have minimal failure. To answer the cause of failure of the gear, 3 stages of testing are carried out, namely; macro observation, chemical composition test and hardness test and loading simulation. The results of this test are that failure occurs due to case crushing caused by residual stresses under the surface of the gears, the detached surface and pinnion conditions exposed to the soft parts become more vulnerable so that scoring occurs causing macrowelding.
