Development of Double-Sided Multipoint Press CNC and Operational Technology for Producing Freeform Molds

Many studies concerning the precision manufacturing of freeform concrete panels have been conducted, however, this process remains labor intensive taking significant amounts time and cost. In particular, in shape produced tends to be low because manual work involved producing curves those panels. This study documents development mold production technologies that can used produce precise curved surfaces on upper lower parts a for A double-sided multipoint press CNC (computer numerical control) produces without need work, while operational technology we developed control tool enhances created. The these was verified through experiments. difference between shapes designed were found using 3D scans quality inspections. Unpredictable errors occur due size certain curvatures, elasticity silicone plate, rotational angle joints rods supporting surfaces. To minimize errors, compensation carried out reverse engineering, leading maximum error 2.887 mm, which is within allowable error. results achieved are step toward will increasingly
