Design and Fabrication of Automatic Metal Plate Cutting Machine
Keywords:automatic cutting machine, design, fabrication, pneumatic
The use of manual plate cutting tools has weaknesses, including low production speeds, uneven pieces of pieces, and expensive production costs. The design process is needed to resolve these problems and manufacturing a knife cutter can automatically operate. This study aimed to design an automatic metal plate cutting machine based on a pneumatic system. The design of this machine is focused on developing cutting machines in the knife manufacturing industry. The method of making machine design consists of movement simulation processes and pneumatic control using fluid simulator software (fluid SIM), cutting machine design using Autodesk inventor software, and mathematical design calculations. The results achieved in this study are prototypes of pneumatic system plate cutting machines that can work automatically with a capacity of 400 pieces per hour, the need for cutting force of 552 N, pneumatic pressure of 6.2 bar, and air debit 11.5 liters/minute. The results of this study show that machine design has several advantages. The manufacturing process is faster, the energy used is relatively small, and the use of labor is more efficient so that productivity increases. Some things recommended to be analyzed in the future include operator work safety factors, periodic maintenance systems, and the ease of getting spare parts.
