<![CDATA[Abstrak: Era globalisasi ini, mesin sistem manual dibiarkan dan diubah oleh mesin sistem otomatis untuk membantu operasi manusia. Dengan demikian makalah ini akan menjelaskan tentang bagaimana objek kerja dalam distribusi otomatis dibuat khusus untuk modul pengumpan (stasiun makan dan stasiun pengangkat) yang dibuat secara modular. Stasiun pakan dalam bentuk papan yang digerakkan oleh pneumatik tanpa batang dan berfungsi sebagai tempat kerja pendorong dimana di angkat sekrup untuk melanjutkan kerja benda ke stasiun berikutnya. Stasiun pengangkat berbentuk palet di lantai 3 yang digerakkan dengan motor DC gerak sudut yang diubah oleh sekrup timah menjadi gerakan linier untuk menyesuaikan ketinggian. Semua proses distribusi ini dikendalikan oleh PLC (Programmable Logic Controller) dalam kapasitas 26 I / O (16 input dan 10 output). Salah satu bahasa pemrograman yang mudah dipelajari adalah Functional Block Diagram (FBD). Pada FBD, ada metode Sequential Function Chart (SFC) untuk menentukan urutan pekerjaan program. Hasilnya adalah mesin simulasi stasiun makan dan stasiun pengangkat dalam skala laboratorium yang dapat memberi makan benda kerja di stasiun berikutnya sepanjang gerak diagram setiap stasiun. ]]>

<![CDATA[The need of machine tools is growing in Indonesia every years, this because of the increasing need of high quality product and short product manufacturing time are the answer for the market needed. CNC machine is a numerical method which the computer is used to control the machine tools, in Indonesia itself are increasing its usage from large scale industry to home industry and as well as in education sector. Education sector need to be up to date to the technology to empowering their students in order to catch up in the technology growth. Investment in CNC machine tools is consider as a high investment for education institution, and industrial CNC machine tools also bulky so it difficult to move around which are difficult to bring it in classroom. To overcome the problem in this paper will discuss about design and analysis of prototype CNC milling machine tool which has working area of 328 mm × 245mm × 100mm and can withstand the force of cutting of 0.044Nm. In this paper also discuss about design and analysis of the machine tools frame using finite element method. Result from the frame analysis with the load from Z direction of 10 kg of load shows the maximum displacement is 0.07558mm and maximum stress is 0.09178 Mpa.]]>

<![CDATA[Abstract: Steel is an iron-carbon alloys containing concentrations of other alloys having a different composition and treatment materials, steel properties can be changed by heat treatment. The heat treatment process serves to increase the strength of a steel material. The nature of the material can be turned into a more robust and resilient heat treatment process, if done properly and correctly. Austempering process is just one example of the heat treatment process at steel that aims to improve the mechanical properties of the steel S 45 C and S 60 C. austempering process performed on the steel S 45 C and S 60 C aims to increase the hardness and toughness of the steel. Austempering process is done by austenisasi advance with temperature 8500C and held for 60 minutes, after which the process is carried out with 3 election austempering temperature of 3500C, 4500C, 5500C and held for 30 minutes. The method used to test the results of austempering is tensile testing using ASTM A370- 12a, Vickers hardness test and microstructure observation using a digital microscope. In the test results tensile steel S 45 C and S 60 C values obtained an increase in ductility and toughness of 17.1 % on steel S 45 C and 17 % on steel S 60 C. This value is obtained from the calculation of ultimate tensile strength test specimens that have not been in austempering process with a specimen that has been in the process of austempering at 3500C , and the results of testing hardness of the steel S 45 C and S 60 C obtained hardness value of 44% increase in steel S 45 C and 46 % on steel S 60 C. value this is obtained from the calculation of the average value of the test specimen is not in the process of austempering with a specimen that has been in the process of austempering at 3500C . ]]>

<![CDATA[The wheeled robot design consists of various modules with their own functionalities. We chosethe components based on theirs specification, autonomous functionality, and in theirs prices. We assembledthese components as modules. The modules in this design are power supply module, processing modulewhich is used ATMega 328 microcontroller, distance sensor module, line sensor module, wirelesscommunication module, motor driver module and actuator module which is used DC motor. Systemperformance indicated with: Able to follow square, triangle, synes conture and stopping ability. Experimentshawed that all of the modules worked as design. The robot could navigate according to contoursautonomously. We tested by using a display module. We gave inputs and then feeded to processing modulethrough bluetooth. From the experiment, it can be concluded that the robot which was using wall followingmethod could be controlled well. The PID controller performed well so the navigation could be stable. Thestable condition was achieved under 3 seconds. But the performance criteria had not been achieved becausethe maximum overshoot was 41.2% which was far from the limit of 10%.]]>

<![CDATA[In the machining process, increased production can be done by increasing the use of cuttingparameters. However, the use of high cutting parameters has an effect on the wear of the cutting toolused. The aim of this research is to analyze the wear and tear that occurs on cutting tools and tool lifewhen cutting AISI 4140 steel by using variations in cutting speed. The machining process uses a CNClathe by turning the surface of the AISI 4140 steel workpiece. The wear criteria are determined when thecutting tool has reached the edge wear limit (VB) of 0.3 mm. Observation and measurement of carbidecutting tools are carried out every 5 minutes the machining process is carried out. If the cutting tool hasnot shown the specified wear value, then the cutting tool then cuts, so that the wear value is obtained.From the research conducted it was found that at a cutting speed of 160 m / min the cutting tool iscapable of cutting for 39 minutes, 13 seconds. At a cutting speed of 180 m / min the cutting tool is capableof cutting for 38 minutes, 14 seconds. At a cutting speed of 200 m / min the cutting tool is capable ofcutting for 33 minutes, 8 seconds. At a cutting speed of 240 m / min the cutting tool is capable of cuttingfor 26 minutes, 3 seconds. Taylor's advanced tool life for the coated carbide cutting tool in turning AISI4140 steel material is: Vc. Tl.0.073 = 8203.]]>
