Users of CMMs are well aware of their advantages for the rapid and accurate checking of workpieces, but how often is the CMM checked? Renishaw's MCG gives rapid test of CMM performance.
New surfacing option for digitising software
The latest version of Tracecut, Renishaw's market leading digitising software, features a new optional surfacing module which will create true CAD surfaces suitable for export to any CAD system
A straightforward point-and-click approach means that the user can see the inspection path as it is generated, and make changes if required.
Using Renishaw OMV for inspection allows manufacturers to detect errors earlier and correct them before the parts are removed from the machine tool.
The ability to check that the part is reaching specification at various stages of the manufacturing process will save time, reduce the amount of scrapped components and increase confidence.
In combination with Renishaw's RENGAGE spindle touch probes, Renishaw OMV provides unrivalled accuracy of part verification on machine tools.
Non-lobing, high accuracy RENGAGE probes, such as the MP700 and new OMP400 ultra-compact touch probe, are ideally suited to the 3D inspection routines made possible with Renishaw OMV.
Surface data is measured and sent to a PC, where powerful measurement algorithms process the data.
Features such as multi-point circles, cylinders, cones, spheres and planes, can now be measured to a high degree of accuracy, and powerful 'best fit' algorithms match groups of measured data to the model, reducing the deviations and errors, by removing alignment and datum constraints.
Renishaw OMV gives clear graphical displays of measured deviations and errors on the CAD model, indicating whether a measured point is in, above or below tolerance, and can produce a 'colour map' of the accuracy of the component.
Tolerance inspection reports provide formal documentation of the component's geometry, which can be combined with views of the CAD model.
Native CAD files that can be used with Renishaw OMV include Auto CAD's DXF and DWG formats, Catia, SDRC, Unigraphics and Pro/Engineer, as well as the standard formats of IGES, Parasolid, STEP and STL.
The software runs on a wide range of machine tools, including those fitted with Fanuc, Mazak ISO, Pro3, Yasnac, Hitachi Seikos, Mitsubishi, Siemens and Heidenhain controllers. Request a free brochure from Renishaw ...
