Software simplifies on-machine
inspection
On machine verification software creates inspection routines using original CAD part models enabling 'done-in-one processing', fast throughput and in-process checks to reduce scrap.
Renishaw extends the efficiencies of on-machine probing with new PC-based inspection software for machine tools, The On Machine Verification (OMV) software is designed to save time and minimize the risk of scrap by making it easy to using probing measurements to verify complex parts while fixtured on the machine tool OMV is especially written for machine tool inspection of prototypes, complex and large parts, multi-operation parts, and die and mold parts, employing original CAD data

MCG gives rapid test of CMM performance
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.
The OMV enables offline programming of probing routines using the CAD model without specialized programming or probing knowledge.
By clicking various features on the modeled part, the inspection path is automatically generated.
Graphical simulation allows offline prove-out of programs in the design office.

With the straightforward point-and-click approach, inspection could not be simpler.
Surface data is measured and sent to the PC, where powerful (CMM style) 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.
The OMV software can be used with high-accuracy Renishaw spindle probes to collect data for in-process quality checks without having to be calibrated in all the intended vectors.
This reduces the number of points required to measure each part, giving significant cycle time improvements.
An open-loop process, OMV inspection provides intelligence for machine operator use in deciding corrections and compensations.
Live data capture to the PC can permit instant feedback on component quality.
The OMV software quickly creates 3D image or HTML reports to highlight non-conformances, letting users select the preferred report style for highlighting essential features.
Graphical inspection reports not only display the measured deviations on the CAD model, but also represent errors with coloured dots.
These dots indicate whether the point is in, above or below tolerance and can be used to produce a 'color map' of the accuracy of the component.
Renishaw OMV is able to 'best fit' groups of measured data to the model, reducing the deviations and errors by removing alignment and datum constraints.
The data can be constrained in the X, Y or Z axis, 2D plane or in rotation only.
The powerful 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.
Renishaw OMV is capable of running on a range of machine tools fitted with Fanuc, Mazak ISO, Pro3, Yasnac, Hitachi Seikos, Mitsubishi, Siemens and Heidenhain controllers.
Renishaw OMV inspection allows machining businesses to detect errors earlier and correct them before the parts are removed from the machine tool, enabling "done in one" process capability.
It can eliminate post-process inspection for faster throughput and lean manufacturing benefits.
Besides saving times, the ability to check that the part is meeting specification at various stages of the manufacturing process can reduce the amount of scrapped components, particularly on complex, high-value parts.
