I am currently in the final year of my Manufacturing Systems degree and am in need of some help with my main project. I must design a Jig to allow irregular, complex items to be measured using a CMM. Irregular shaped objects are difficult to measure accurately using a CMM due to the fact that the vertical access Required from the probe cannot always be obtained. It is therefore necessary to measure the part in different sections, such as an upper half and a lower half. It is proposed that a jig be designed and manufactured that would allow a complex part to be held on the measuring table of the CMM and moved in such a way as to be able to measure the whole of its surface. The system would then need to be demonstrated with an example part.
Has anybody got any ideas. ?
I need information on existing systems and methods, materials, tolerances and designs.
If any body can help I would be most grateful.
I would also be very interested in visiting a site using such an application. Anywhere in the North of England would be very helpfull !
Thanks again, Chris Lane
