What is the INORAsrs?
The INORAsrs artifact is a highly precise nominal 3D structure combined with INORA Core Technology driven evaluation software. Standard bar lengths of 400 mm, 1000 mm, 1500 mm and 2000 mm are available, and custom bar lengths of any size can be produced on request. The INORAsrs bars are a unique combination of carbon fiber and precision steel, combined with patented mechanical temperature compensators. These compensators keep the bars of the artifact the same length, regardless of influences from temperature, humidity or pressure. The artifact itself can be assembled in less than two minutes, is disassembled just as quickly, and can easily be carried by a single person.
Back To TopWhat kind of machines can I verify with the INORAsrs?
The INORAsrs is designed to validate production and measurement instruments including (but not limited to): robots, CNC machine tools and CMMs of all types (Portable or Stationary).
Back To TopWhat role does the INORA Core Technology (INORAme) play in the INORAsrs software?
First, INORAme is able to automatically differentiate between unexpected deviations and measurement uncertainty within the sphere measurements. Using a minmax calculation, this allows INORAme to determine the true sphere centers, which is the first step in providing reliable results. Based on the true center of each sphere we are able to calculate, out of a 12 parameter transformation, the error in each of the six main parameters of your equipment’s coordinate system. Additionally, following first principles, we can accurately determine how well your equipment can define a nominal 3D volume. These results, given by the INORA Core Technology within the INORAsrs software, provide a clear picture of your machine’s capability at any time.
Back To TopHow long does it take to perform INORAsrs verification?
Verification with the INORAsrs is a quick process, usually a matter of only 10 to 20 minutes; mainly depending on the time it takes for the particular device to probe four spheres.
Back To TopWhy use the INORAsrs tetrahedron compared to a common 1D length check?
One of the strongest and most unique characteristics of the INORAsrs is that it provides a clear picture of machine accuracy over a given volume. Unlike a conventional length check, the INORAsrs is a true 3D artifact, and represents a nominal 3D volume. With a single evaluation, the INORAsrs and the Core Technology driven software provide a complete picture: Scale analysis for the X, Y and Z axes, Squareness analysis for the XY, XZ and YZ axes of a machine coordinate system, and an accurate determination of how well your equipment can define a nominal 3D volume. Additionally, this information is presented in an easy to understand fashion with a simple "go" or "no go" indication for results.
Back To TopHow often do I have to calibrate the INORAsrs?
Although the results provided by the INORAsrs are the most robust available today, the artifact itself must be treated with care as it is highly accurate. Under normal conditions, we recommend that the bars of the artifact be recalibrated on a yearly basis. However, they should also be recalibrated if they are subjected to any violent incident such as a fall.
Back To TopCan the INORAsrs extend the calibration cycle of my machine?
Since the INORAsrs provides the ability to assess and trend the capabilities of a machine over time, calibration cycles can be optimized based on individual machine performance.
