On-machine and in-process surface metrology are important for quality control in
manufacturing of precision surfaces. The classifications, requirements and tasks of on …

Flatness deviations in the tandem cold-rolling process of steel strips have a direct impact on
product quality and shape, leading to strip breakage, reduced working speed, and …

Geometric dissimilarity between the thickness profile of the entry strip and the deformed roll
gap is the main cause of flatness defects. However, the combination of the crown ratio and …

Modern hot strip mill process (HSMP) is increasingly characterized by producing small-
batch, multi-specification and high-value-added products. Associated with such suffered …

Steel rails used in the transport sector and in industry are designed and manufactured to
support high stress levels generated by high-speed and heavy-loaded modern trains. In the …

The advanced SmartCrown technology, one of the Variable Crown by Axial Shifting (VCAS)
technologies, can significantly enhance the cross-directional control capability of strip mill …

Measuring rail profile in the presence of multiple degrees of freedom vibration is a very
challenging task. This paper presents a novel method based on the local affine invariant …

3D reconstruction based on laser light projection is a well-known method that generally
provides accurate results. However, when this method is used for inspection in uncontrolled …

Accurate and rapid recognition of flatness defects is important to produce high‐quality cold
rolling strips. First, this study collects the flatness defect images and creates the first image …

A computer keyboard is an important human-machine interaction device. A key-cap and a
keyboard are flexibly connected, and its assembly quality, especially flatness, is crucial. In …
