Optimization of the Toolpath Strategy for the Master Ceramic Jewelry Mold Pattern Using the Rhinoceros Software and Router CNC Machine

Abstract

The progress of the manufacturing industry is very dependent on the development of science and technology. The current industrial revolution 4.0 encourages people to think more creatively in developing their business units. The creative economy helps the government of the Republic of Indonesia to increase state revenue from the export of these manufactured industrial products to other countries. This is also supported by the habits of the Indonesian people who are consumptive to increase people's purchasing power of these products, one of which is ceramic products. The ceramic industry in Indonesia is currently growing rapidly and getting full support from the government to increase its competitive advantage so that it can compete with local and international ceramic products. Ceramic products, including textiles, tableware, and jewelry. One of the efforts to increase the added value of this product is the use of CAD / CAM artistic technology with a CNC machine. Ceramic designs by providing additional motifs with complex relief contours and distinctive cultural or regional characteristics can be added with the use of reliable artistic CAD software such as ArtCAM and Zbrush. The master prints of artistic patterned products with Indonesian batik reliefs are obtained using a CNC router machine with precise and accurate quality. Optimization of manufacturing so that the cutter trip on the CNC machine runs optimally is used Rhinoceros 4.0 software. Two optimal machining strategies, namely horizontal roughing and parallel engineering in the CAM software, are used by researchers to obtain the NC code and the optimal patterned jewelry ceramic product master. A CNC router machine with a capacity of 1.5 kWh with workbench 800 x 600 mm is used for the manufacturing process. The results showed that the application of this technology in the local ceramic industry was able to reduce the design and manufacturing time of jewelry ceramics about3-5 days faster. The total design work from the CAM simulation stage to the jewelry product master was 8.0 hours.
