Abstract

Industri manufaktur di Indonesia berperan penting dalam mendukung pertumbuhan ekonomi melalui kontribusi signifikan terhadap PDB dan penciptaan lapangan kerja. Salah satu proses manufaktur yang banyak digunakan adalah proses milling. Mesin milling konvensional umumnya hanya memiliki 3 sumbu (X, Y, Z) sehingga kurang efisien untuk pengerjaan bidang kerja berbentuk silinder atau yang membutuhkan proses bolak-balik. Oleh karena itu, penelitian ini merancang dan membangun sistem elektrikal pada mesin milling 4 axis yang dapat melakukan pergerakan empat sumbu dengan penambahan sumbu putar (A axis). Sistem elektrikal dirancang menggunakan mikrokontroler Arduino Mega 2560, modul RAMPS 1.6, motor stepper Nema 17, driver DRV8825, dan LCD I2C 20x4 sebagai tampilan koordinat. Fungsi pengendalian motor stepper diatur melalui push button untuk arah gerak dan potentiometer untuk kecepatan. Pengujian dilakukan melalui metode Jogging Test, Parameter Test dan Performance Test untuk mengevaluasi keakuratan pergerakan sumbu. Hasil pengujian menunjukkan bahwa mesin mampu bergerak dengan presisi tinggi dengan rata-rata selisih maksimal 0,2 mm pada sumbu X dan Y. Dengan demikian, mesin milling 4 axis ini berhasil diuji dan mampu meningkatkan fleksibilitas dan efektivitas proses pemesinan, khususnya untuk bidang kerja berbentuk kompleks yang sulit dijangkau oleh mesin 3 axis konvensional.

The manufacturing industry in Indonesia plays an important role in supporting economic growth through its significant contribution to GDP and job creation. One of the most widely used manufacturing processes is milling. Conventional milling machines generally only have 3 axes (X, Y, Z) so that it is less efficient for working cylindrical work fields or those that require alternating processes. Therefore, this research designs and builds an electrical system on a 4-axis milling machine that can perform four-axis movements with the addition of a rotary axis (A axis). The electrical system is designed using Arduino Mega 2560 microcontroller, RAMPS 1.6 module, Nema 17 stepper motor, DRV8825 driver, and 20x4 I2C LCD as coordinate display. The function of controlling the stepper motor is set through a push button for the direction of motion and potentiometer for speed. Testing is done through the Jogging Test, Parameter Test and Performance Test methods to evaluate the accuracy of the axis movement. The test results show that the machine is able to move with high precision with an average maximum difference of 0.2 mm on the X and Y axes. Thus, this 4-axis milling machine was successfully tested and was able to increase the flexibility and effectiveness of the machining process, especially for complex work areas that are difficult to reach by conventional 3-axis machines.
