Mould-based processes are the predominant technique to create large scale building elements. While digitalisation increasingly underlies the design and description of moulds, their making is disconnected from the digital chain and remains a highly manual process, with skilled craftsman required to fabricate complex geometries up to 6m size at 1mm precision. The aim of this project is to digitize the production environment and improve precision and quality control in the mould making process by enabling direct and easy measurement and checking processes against a digital model, from the factory floor.
This project develops PrecisionPartner - a mobile robotic solution that uses Build 4.0 technologies to enable digital precision, quality assurance and direct feedback in physical craft-based production.
PrecisionPartner develops and connects four key interacting considerations:
• Proposing a methodology and associated automated modelling tools that ensure precise geometric definition and enable automated calibration of 3D scans during production
• Prototyping a mobile station capable of 3D scanning large moulds comprehensively, with automatic registration of scans from multiple positions
• Demonstrating automatic comparison between the captured 3D pointcloud and the digital model, and detection and quality report of deviations of dimension and surface geometry
• Exploring and creating ‘factory floor’ protocols for feedback of deviations directly on the mould, via marking directly on the mould using a robot arm.
