    Abstract
    Pada penelitian ini, telah dilakukannya pembubutan yang bertujuan untuk mengukur dan menganalisis suhu pemotangan dengan menvariasiakan parameter pemotongan (v, f, a) pada pemesinan keras baja AISI 4340 menggunakan pahat CVD berlapis Al2O3/TiCN Produk Kennametal. Suhu pemotongan rata-rata diambil menggunakan Video Infrared Thermometer. Pengumpulan data penelitian dilakukan menggunakan metode faktorial 23. Dilakukannya simulasi disitribusi suhu pemotongan baja AISI 4340 dengan menggunakan pahat karbida CVD dengan konteks pemesinan orthogonal 2D menggunakan perangkat lunak elemen hingga ABAQUS/CAE. Pada simulasi yang dilakukan menggunakan perangkat lunak ABAQUS/CAE digunakannya metode empat node bilinear displacement dan temperature (CPE4RT). Hasil yang didapatkan melalui simulasi menunjukan suhu pemotongan yang terdapat pada mata pahat 106oC – 283oC; suhu geram 186oC – 343oC; dan suhu benda kerja 38oC – 68oC.
     
    In this study, the turning attempt has been made to investigate and analyze the cutting temperature with varying cutting parameter (v, f, a) on the hard machining steel AISI 4340 used carbide CVD tool with coating (Al2O3/TiCN) Kennametal Product. The average of cutting temperature measured using Video Infrared Thermometer. Experiment data collected by using 23 factorial method. The distribution of cutting temperature AISI 4340 steel using carbide CVD tool was simulated in 2D orthogonal cutting using by finite element method software ABAQUS/CAE. Simulation was using by ABAQUS/CAE with four node bilinear displacement and temperature (CPE4RT). The simulation result shows cutting temperature on tool is 106oC – 283oC; on chip 186oC – 343oC; and on the workpiece 38oC – 68oC.
