Abstract
<p><em><span lang="EN-US">The purpose of this research is to design and implement an automatic acrylic carving and cutting tool using a microcontroller-based 3-axis CNC machine. Computer Numerical Control (CNC) is a machine technology that is operated automatically to support the demand for a product that has a complex shape and high accuracy. In general, the construction of a 3-axis CNC machine and its working system is synchronization between the computer and its mechanics. This tool has a work process by utilizing the G-Code method as a command on the machine to carry out engraving and cutting automatically. The G-code was obtained from a previously designed image and then converted using the Aspire 9.0 software. Engraving and cutting is done by sending the G-code file to the microcontroller via the Universal G-code Sender software, then the microcontroller sends a signal to drive the motor driver which then drives the stepper motor so that the actuator movement is generated according to the image in the G-code file. Simultaneously the spindle motor will be active to engrave or cut acrylic. In this study, a trial scenario was carried out to determine the precision and accuracy of the tool, namely by engraving and cutting flat shapes such as squares, circles, triangles and segments. The percentage of success generated from this tool is 97,08% to 100%. Furthermore, testing is carried out to make products in the form of engraving writing, logos and calligraphy. Apart from that, we also tested cutting letters and key chains. When the test is carried out, the accuracy level is 1mm. </span></em></p>

Summary
Pada era revolusi industri yang telah memasuki revolusi industri 4.0 mengakibatkan perkembangan dunia industri menjadi sebuah industri yang berteknologi cerdas. Perkembangan mesin teknologi yang diciptakan sebagai alat mempermudah kegiatan manusia dengan penggunaan teknologi komputer ke dalamnya sehingga berdampak pada penggunaan sistem otomasi. Maka pekerjaan-pekerjaan yang dilakukan secara otomatis sehingga mempermudah dan menghemat tenaga manusia. Sehingga alat tersebut dapat membuat suatu karya seperti gantungan kunci, plakat, kotak barang dan benda seni lainnya.[6] Oleh karena itu, penulis melakukan suatu penelitian berjudul Rancang Bangun Mesin Ukir dan Pemotong Akrilik Menggunakan CNC Milling 3Axis Berbasis Mikrokontroler. Penelitian ini difokuskan pada pemilihan komponen sistem kontrol, perakitan sistem interface, sehingga konstruksi mekanik mesin CNC terhubung dengan mikrokontroler yang dikendalikan oleh personal computer (PC) sehingga menghasilkan mesin CNC yang bekerja dengan maksimal sebagai teknologi tepat guna dalam membantu pekerja industri kreatif dibidang akrilik. Selain itu alat tersebut diharapkan dijadikan suatu inovasi oleh mahasiswa dalam membuat suatu karya maupun benda pendukung yang berbahan akrilik.[7][8]
