Model of the world's largest statue. (Newsdesk).

A dedicated team at CADCAM software developer Delcam has completed the CAD model of the Maitreya Buddha that will be used as the basis of the world's largest statue. The CAD model has been created with Delcam's CopyCAD reverse engineering software from scan data captured from a life-size sculpture using a Breuckmann optical scanner.

The completion of the CAD model is one of the key stages in Delcam's technical support for the Maitreya Project, a major religious development in Bodh Gaya, India, that will include the construction of the 152.4 metre statue. The statue will be made from approximately 8000 two-metre square cast bronze panels, aligned and secured to a vast civil engineering structure.

The scan data was captured from a 'master sculpture of the Maitreya Buddha created by sculptors Peter and Denise Griffin, on the basis of ancient scriptures and the wisdom of Buddhist masters such as Lama Thubten Zopa Rinpoche.

The surfacing process has been used to enhance the aesthetic quantity of the Maitreya form. For example, CopyCAD has allowed the artists to add symmetry and uniformity to the face of the statue.

The CAD model will used as the master model for all the subsequent processes. The individual panels will be cut from the model data with Delcam's PowerSHAPE modelling software. The same software will then be used to create a wall thickness, and to add expansion joints, inspection targets and other civil engineering features.

Once each unique panel has been developed in PowerSHAPE, PowerMILL will be used to create toolpaths for the production of moulds. Currently the preferred process entails machining the mould cavities directly into solid blocks of 'green sand'. Delcam will be supporting the machining of moulds on-site at the selected casting foundry in India, in order to machine moulds and cast the bronze with minimal handling of either the brittle sand moulds or the heavy bronze castings.

Each bronze panel will be inspected with Delcam's inspection system, PowerINSPECT, against the original CAD model to ensure that it is correct to tolerance before it is added to the civil engineering structure of the statue. This process will ensure that time is not invested downstream only to find errors in individual panels later in the assembly process.
