Virtual Unclamping

Software Simulation

Application of finite element analysis to the measured data points simulates the relaxation of internal stresses. In the process of virtual unclamping, the software calculates the effect of gravity and residual forces on the geometry of the part. This digital approach is much faster than building and maintaining multiple physical inspection fixtures.

Gravity Correction

Removal of the weight factor is necessary to see how the part would look in a zero gravity or fully supported but unconstrained state. By using virtual unclamping, technicians can identify whether a deviation is a genuine manufacturing defect or simply the result of the part’s own mass. This distinction is necessary for providing accurate feedback to the production team.

Inspection Speed

Reduction in the time required for metrology checks is a notable benefit for high volume manufacturing lines. Because virtual unclamping replaces the need for complex mechanical setups, parts can be scanned in a simple cradle and then analyzed in the cloud. This flexibility enables more frequent sampling and better control over the manufacturing process.

The ability to simulate various assembly conditions from a single scan provides a deeper understanding of part performance than traditional methods.
