Abstract

Perlunya akurasi dimensi pada hasil pemotogan styrofoam guna memenuhi kebutuhan pasar, maka dirancang alat guna membantu produsen industri kreatif stryrofoam. Oleh karena itu, pada tugas akhir ini penulis membuat mesin pemotong styrofoam menggunakan hot wire sehingga bisa memotong lebih efektif. Pada aktuator elemen pemanas menggunakan kawat dengan bahan NiCr 80 dan diameter 0.32 mm agar mendukung design benda kerja yang rinci. Pada alat ini digunakan mikrokontroller Arduino Uno guna mengontrol sistem kerja alat. Pemotongan dilakukan dengan mengirimkan file g-code kepada mikrokontroler melalui software Universal G-code Sender, kemudian mikrokontroler mengirimkan sinyal untuk menggerakkan driver motor dan driver motor menggerakkan stepper motor sehingga dihasilkan gerakan aktuator sesuai dengan gambar pada file g-code.Pengujian akurasi dimensi hasil pemotongan mengguanakan 3 desain benda kerja yang berbeda. Setiap desain beda kerja diuji coba sebanyak 3 kali. Setelah dilakukan pengujian pada styrofoam jenis expanded polystyrene (EPS) dengan ketebalan 1.5 mnggunakan parameter pemotongan tegangan 5.5 V dan feedrate 600 mm/min diapat rata-rata akurasi dimensi benda kerja mencapai 97.55%, dengan rincian hasil benda kerja 1 memiliki nilai akurasi dimensi 97.93%, benda kerja 2 memiliki nilai akurasi dimensi 95.90%, dan benda kerja 3 memiliki nilai akurasi dimensi 99.22%. Semakin besar dimensi benda kerja maka nilai akurasi dimensi yang dihasilkan juga cukup tinggi.

The need for dimensional accuracy in the results of Styrofoam driving to meet market needs, a tool was designed to help manufacturers of the creative industry of Stryrofoam. Therefore, in this final project, the author makes a Styrofoam cutting machine using hot wire so that it can cut more effectively. The heating element actuator uses wire with NiCr 80 material and a diameter of 0.32 mm to support a detailed workpiece design. In this tool, an Arduino Uno microcontroller is used to control the working system of the tool. Cutting is done by sending the g-code file to the microcontroller through Universal G-code Sender software, then the microcontroller sends a signal to drive the motor driver and the motor driver drives the stepper motor so that the actuator movement is produced according to the image in the g-code file. Dimensional accuracy testing of cutting results using 3 different workpiece designs. Each different design was tested 3 times. After testing on styrofoam-type expanded polystyrene (EPS) with a thickness of 1.5 using a cutting voltage parameter of 5.5 V and a feed rate of 600 mm/min the average dimensional accuracy of the workpiece reached 97.55%, with the details of the results of the workpiece 1 having a dimensional accuracy value of 97.93%, workpiece 2 having a dimensional accuracy value of 95.90%, and workpiece 3 having a dimensional accuracy value of 99.22%. The larger the dimensions of the workpiece, the resulting dimensional accuracy value is also quite high.
