Parts with high-quality freeform surfaces have been widely used in industries, which require
strict quality control during the manufacturing process. Among all the industrial inspection …

In recent years, on-machine measurement (OMM) technology, which uses a touch-trigger
probe (TTP) installed on the machine tool (MT) spindle, has become increasingly popular …

Many automated processes such as auto-piloting rely on a good semantic segmentation as
a critical component. To speed up performance, it is common to downsample the input …

Coordinate measurement machines (CMMs) have been widely used in inspecting
mechanical parts with higher accuracy. Both the distribution and the number of the sampled …

Efficient sampling methods enable the reconstruction of a generic surface with a limited
amount of points. The reconstructed surface can therefore be used for inspection purpose. In …

The components with freeform surface are widely used in industrial fields. The machining
quality of freeform surface becomes increasingly significant. Coordinate measuring machine …

Measurements of free-form surfaces are performed with the use of numerically controlled
CMMs on the basis of a CAD model, which results in obtaining coordinates of discrete …

Blade is one of the most important parts in turbine machinery. The complex geometry of
blades not only makes them difficult to fabricate, but also leads them difficult to inspect …

Free-form surfaces have been widely used in aerospace, automotive and other fields. Due to
its complex geometry, free-form surface inspection is generally conducted by touch-trigger or …

Compared with the traditional 3-axis coordinate measuring machine (CMM), a 5-axis CMM
equipped with the capability of continues sweep scanning can provide much denser data …
