Abstract

The development of manufacturing technology demands mastery of precise and efficient CNC lathe machines, but direct practice is often hampered by limited facilities, operational costs, and the risk of programming errors. This study aims to implement CNC lathe simulation based on Nanjing Swansoft CNC Simulator (SSCNC) in the manufacture of paper weight products as a medium for program verification and learning. The research methods include product design, machining parameter calculation, CNC program preparation using G-Code and M-Code based on FANUC 0i-T control, and testing through two machining stages. The workpiece has an initial diameter of 50 mm and a length of 54 mm with a chuck exit length of 40 mm at each stage. The cutting parameters used are a spindle speed of 1000 rpm and a feed rate of 0.5 mm/rev with an absolute programming system (G90). The tool configuration consists of a VNMG 350 carbide turning tool, an Ø18 mm drill, and a 2 mm internal grooving tool. The simulation results show that the two-stage program can be run without syntax errors, interpolation alarms, or tool path conflicts. The G02/G03 circular interpolation successfully generated a continuous radius, and all geometric features were formed according to the working drawings. The SSCNC simulation proved effective as a safe technical verification and learning medium before practicing on a real CNC machine.

Abstract

The increasing need for fast delivery drives the development of drones as an alternative logistics solution. However, increasing payload capacity impacts thrust requirements, power consumption, and structural stability, necessitating integrated mechanical design. This study aims to design a mechanical system for a 2-3 kg package delivery drone with a stable and energy-efficient quadcopter configuration at maximum payload conditions. The method used is a design engineering approach through 3D CAD modeling, mass distribution and center of gravity (CoG) analysis, and thrust and power estimation using momentum theory. Evaluations were carried out on the total system weight, hover thrust requirements, hover power, and peak power with a thrust-to-weight (T/W) ratio of 1.8-2.0. The results show that at a total mass of ±6.5 kg, a minimum thrust of approximately 1.63 kgf per motor is required for stable hovering. The estimated hover power is around 1.04 kW, while the peak power is close to 3 kW. The 6S 15,000 mAh battery configuration is capable of providing a hover duration of approximately 15 minutes. This design demonstrates technical feasibility for medium-scale logistics drone applications.

Abstract

Closed circulation aquaponic systems require proper piping design and pump selection to ensure flow stability, energy efficiency, and operational sustainability. This study aims to design and experimentally validate an aquaponic piping system based on major and minor head loss analysis and determination of Total Dynamic Head (TDH) as the basis for pump selection. The methods used include theoretical calculations using the Darcy Weisbach Equation, system curve construction (HQ), and experimental testing through measurements of actual discharge, pressure, and pump electrical power under real operating conditions. The results show that minor head loss dominates the total energy loss (±66%), while major head loss contributes ±34%. The system TDH is obtained at ±2.2-2.4 m at a design discharge of 24 L/min. Experimental testing shows an actual discharge of 22–23 L/min with a deviation of <8% from the theoretical calculation. Actual pump power shows operational efficiency in the range of 48–55%. Pipe diameter sensitivity analysis shows that increasing the main diameter by 1 level can reduce head loss by 18–25% and reduce pump power requirements by ±12%. These results confirm that optimizing fitting layout and diameter selection has a greater impact on system efficiency than simply increasing pump capacity. This research contributes a system curve-based design approach and experimental validation to improve the reliability and energy efficiency of closed-circulation aquaponics systems.
