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.

Abstract

The interior warehouse at PT. XYZ, a bus body manufacturing company, experiences operational inefficiencies due to the implementation of a Dedicated Storage system. This system leads to non-optimal picking times and long travel distances for operators, especially during peak activity periods (rush hour), because high-movement items are not strategically placed near the Input/Output (I/O) point. This research aims to optimize the warehouse layout by implementing the Class-Based Storage method based on ABC classification. Data on item movement (inbound and outbound) over 12 weeks were collected and analyzed. The ABC analysis categorized items into three classes: A (fast-moving), B (medium-moving), and C (slow-moving). The results show that four items (Snap ring outer, Masking Tape, Karet O-ring, and Transition Board) belong to Class A, contributing to 74% of the total movement frequency. The proposed layout places Class A items closest to the I/O point, Class B in the middle area, and Class C on the second floor. This systematic reorganization is expected to significantly reduce picking time and travel distance, improve space utilization, and ultimately enhance overall warehouse productivity and support smoother production operations at PT. XYZ.
