Jogbox 3D Scanner CMM Hybrid Metrology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coordinate measuring machines (CMMs) face challenges in efficiently measuring objects with varying precision requirements, as they often need to balance high accuracy for critical features with faster, less accurate scanning for other areas.
Innovation Solution
The integration of a jogbox with a 3D scanner into CMM systems allows for the use of the scanner for less precise measurements and the CMM for high-accuracy measurements, optimizing the measurement process by leveraging the strengths of both technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a CMM is used to measure all portions of an object, then measurement precision is improved, but measurement time increases
Solution Approach 1:
The measurement process is segmented into two distinct portions: a first portion measured using rapid scanning technology and a second portion measured using the CMM. This segmentation allows different measurement strategies to be applied to different parts of the object, optimizing both speed and precision where needed.
Solution Approach 2:
Different measurement qualities are applied to different portions of the object based on their specific requirements. The first portion receives rapid, lower-precision scanning while the second portion receives high-precision CMM measurement, matching the measurement quality to the local needs of each area.
2Speed
If a 3D scanner is used to scan the object, then scanning speed is improved, but scanner accuracy is reduced compared to CMM accuracy
Solution Approach 1:
The rapid scanner is used to capture the first portion of the object that requires less precision, performing a partial measurement that is sufficient for those areas. This allows the system to use the faster, less accurate scanner where full CMM precision would be excessive and unnecessarily time-consuming.

AI summary
A method measures an object using a CMM having a CMM accuracy. To that end, the method provides a jogbox with a 3D scanner having a scanner accuracy, positions the object on the CMM, and scans, using the 3D scanner, the object to produce scan data of the object. The method also measures a first portion of the object using the scan data, and a second portion of the object using the CMM. The CMM accuracy is more accurate than the scanner accuracy.
