Machine Acceleration Effects on Computer Controlled Polishing
| Description | Through the method developed in this project, a better surface finish can be achieved in metal mirror polishing |
| Exploitation Route | We are deploying the outcome in our other projects. |
| Sectors | Aerospace, Defence and Marine,Manufacturing, including Industrial Biotechology |
| Title | Epicyclic smoothing tool |
| Description | An Epicyclic smoothing tool has been developed to be able to used at robot facilities to smooth grinding marks. This tool is much more efficient in coping mid-spatial features. |
| Type Of Material | Improvements to research infrastructure |
| Provided To Others? | No |
| Impact | This tool will enable a fast process of mirrors or lens from grinding state to polishing state. This will bridge the gap between these two stage on processing and metrology. |
| Title | Epicyclic database |
| Description | This database provide recommanded process parameters when input with parts size, shape, form target. |
| Type Of Material | Database/Collection of data |
| Provided To Others? | No |
| Impact | This database will potentially be used by our research collaborators in their research and development programmes. |
| Description | Collaboration agreement with Harbin Institute of Technology (HIT) |
| Organisation | Harbin Institute of Technology |
| Country | China |
| Sector | Academic/University |
| PI Contribution | We at Glyndwr University agreed to provide technical assistance and training opportunity for students and academic visitors. We also agreed to submit joint papers to peer-reviewed journals. |
| Collaborator Contribution | Collaborator at HIT agreed to provide experimental work, including technican's access of the lab equipments. |
| Impact | * One conference paper has been published * One journal paper is being edited * The PI Glyndwr has visited HIT * The collabator from HIT has visited Glyndwr University |
| Start Year | 2014 |
| Description | Collaboration with Zeeko Ltd. |
| Organisation | Zeeko Ltd |
| Country | United Kingdom |
| Sector | Private |
| PI Contribution | We have developed software that is suitable for industrial robots to perform intermediate process between polishing and grinding. |
| Collaborator Contribution | Zeeko has provided a FANUC robot to facilitate research and development programmes and some technical assistant on facility development. |
| Impact | 1. The process developed from this project will be adopted by other projects. e.g. LOCUS M1 processing. 2. Zeeko has commercial interest for this process. |
| Start Year | 2014 |
| Description | Collaborations with OpTIC Glyndwr |
| Organisation | OpTIC Glyndwr Ltd |
| Country | United Kingdom |
| Sector | Private |
| PI Contribution | Provide technical assistance on using Zeeko software to process commercial products. |
| Collaborator Contribution | Provide assistance on smoothing experimental samples |
| Impact | We have produced with collaboration of a test reference mirror for LOCUS project. |
| Start Year | 2015 |
| Title | Epicyclic Toolpath Generation with ABB and FANUC machine settings |
| Description | This is an add-on package to a commercial software which enable intelligent polishing machines to produce ultra precision optical surfaces. This software package can generate optimised toolpath to minimise surface error. This software also have the option to operate on ABB and FANUC industrial robots. |
| Type Of Technology | Software |
| Year Produced | 2015 |
| Impact | This software will enable a process that will shorten total fabrication time by parallel processing. In addition, the optimised toolpath offer a surface with improvement on mid-spatial errors. |
