Abstract

Operasional mesin CNC laser G-Weike LC6090 untuk proses cutting menggunakan seting parameter yang sesuai agar dapat memotong material secara optimal. CNC laser tersebut diketahui seting parameter pada mesin dilakukan secara perkiraan atau asumsi dikarenakan tidak adanya acuan tabulasi level parameter seting pada mesin tersebut yang menyebabkan proses cutting pada CNC laser tersebut kurang optimal. Kesalahan seting mesin dapat mengakibatkan ketidaksesuaian hasil proses, sehingga proses seting diulang kembali secara trial error. Penelitian ini merupakan lanjutan penelitian sebelumnya terkait optimasi proses engraving. Penelitian ini berfokus terhadap optimasi level seting parameter mesin CNC laser G-Weike LC6090 untuk proses cutting. Material yang digunakan adalah akrilik berketebalan 3mm, 5mm, dan 10mm. Parameter seting yang digunakan adalah kecepatan potong (speed) dan kekuatan laser (power). Metode optimasi menggunakan kombinasi Simplex Centroid Design dan optimasi plot multirespon. Parameter respon yang digunakan adalah waktu aktual proses, dimensi panjang dan lebar dari hasil potong. Hasil penelitian ini menunjukkan level seting proses cutting yang optimal untuk akrilik berketebalan 3mm sebesar 1.93037mm/s untuk speed dan 56.6963% untuk power. Akrilik berketebalan 5mm diperoleh level seting optimal sebesar 2.6mm/s untuk speed dan 55% untuk power. Akrilik berketebalan 10mm diperoleh level seting optimal sebesar 1.1535mm/s untuk speed dan 59.539% untuk power.Kata Kunci: CNC laser, cutting, optimasi, Simplex Centroid Design, plot multirespon

Abstract

The wood industry faces prolonged production times due to the use of conventional tools and the declining number of artisans. This study aims to design the CNC 2413 machine to meet the production needs of the interior design industry by improving efficiency, precision, and adaptability. The design process applies the Reverse Engineering approach combined with Design for Manufacturing and Assembly (DFMA). The key technical aspects include torque calculation, Center of Gravity (CoG) analysis, and assembly mapping. The results indicate that a 3-axis CNC router is sufficient for cutting and engraving tasks, requiring a minimum torque of 0.4116 N·m (Y-axis), 0.3528 N·m (X-axis), and 0.0156 N·m (Z-axis), with a spindle torque of 0.159 N·m. The Nema 24 stepper motor and Bosch GKF router were selected as they meet the specified requirements. The CoG analysis produced X = 56.9–63.0 cm, Y = 100.9–127.3 cm, and Z = 3.884 cm, demonstrating structural stability and resistance to vibration. This design is considered feasible and reliable for long-term use. In addition, the study offers practical significance in terms of potential production cost savings through lower power consumption compared to conventional machines and the opportunity to enhance the production capacity of small and medium enterprises (SMEs) in the interior design sector. This research provides a practical reference for developing CNC routers using locally sourced components, aligned with the technical and economic needs of the interior design industry.
