Precision Machined Part Inspection With 3D Profilometry

Precision machined parts manufacturing calls for stringent inspection to ensure product quality and repeatable production standards. The 3D surface inspection of the part compared to CAD model is essential to verify part tolerance and machine quality. Moreover, during the service time, wear and tear of the parts may create surface defects such as scratches, dents and cracks. The part needs to be replaced when the deviation from the required specification is over the tolerance limit. Unlike a touch probe technique, the Nanovea ST400 Profilometer performs 3D surface measurement without touching, making it possible to precisely scan parts with a complex shape at a high speed.

Mechanical Properties of Hydrogel using Nanoindentation

In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the hardness, elastic modulus and creep mechanical properties of a Hydrogel sample. In this case a sample of Hydrogel can simply be placed on a glass slide due to the softness and low load being used to test; testing could also be preformed while in liquid. For this soft material a 3mm spherical tip will be used. This is to give good information on the Hydrogel and not on surface properties that might be different. This can be studied using a shaper Berkovich tip.

Fresnel Lens Dimension Measurement Using 3D Profilometry

A Fresnel lens is extensively employed in industry, such as automobile, lighthouses, solar energy and optical landing system for aircraft carriers. The inexpensive production of Fresnel lenses can be completed by molding or stamping them out of transparent plastic. The service quality of the Fresnel lenses mostly depends on the precision and surface quality of the concentric rings lenses. Unlike a touch probe technique, the Nanovea Profilometer performs 3D surface measurement of the sample without touching, avoiding the risk of making new scratches during the surface measurement. The chromatic confocal technique is ideal for precise scan of a complex shape, such as lenses of different geometry.

Tribology Study of Dental Dog Treat Friction

Flavored dental treats have been demonstrated as an effective, comfortable and easy to use method for dog dental cleaning. The Flavorful and chewy dental treats make teeth and gums cleaning an enjoyable procedure. During the chewing mechanical actions, the dental treat creates friction against the surface of the teeth to remove tartar and bacteria films. A reliable tribology study is needed to quantitatively compare the effectiveness of dog dental treats of different surface texture and roughness, and to provide insight of the correlation of the surface roughness, texture and friction to facilitate the R&D and quality control of the dental treat production.

Flatness Measurement of Screen Using Fast 3D Profilometry

Flatness measurement is an important geometric surface quality in the manufacture of precision parts and assemblies. Flatness of the surface plays a vital role in the end use of the product. For example, the parts that are connected in an air-tight or liquid-tight manner across a surface area require stringent surface conditions of superior flatness at the contact face. Flatness of the screen is critical to the functionality and aesthetics of electronic devices such as cellphones, pads and laptops. Any imperfection of the screen flatness can create negative user impression and experience of the product.

Microindentation Mapping on Glass

Microindentation mapping has proven to be a critical tool for surface mechanics related studies. Fracture has typically been evaluated by measuring the dimension of the cracks of the indent, and the use of acoustic emission during testing has been an overlooked and valuable tool. Microindentation with the measurement of Acoustic Emissions (AE) provides a reliable and user-friendly method to track the fracture behavior and intensity during loading and unloading process.

Inline Roughness Inspection Using Chromatic Confocal Optics

Inline roughness inspection of surface defects derive from materials processing and product manufacturing. In-line surface quality inspection ensures the tightest quality control of the end products. The Nanovea 3D Non-Contact Profilometer utilize chromatic confocal technology with unique capability to determine the roughness of a sample without contact. Multiple profiler sensors can be installed to monitor the roughness and texture of different areas of the product at the same time. The roughness threshold calculated real-time by the analysis software serves as a fast and reliable pass/fail tool.

Micro Scrape Test Of Polymeric Coating

Scratch testing has developed to be one of the most widely applied methods to evaluate the cohesive and adhesive strength of the coatings. The critical load, at which a certain type of coating failure occurs as the applied load progressively increases, is widely regarded as a reliable tool to determine and compare the adhesive and cohesive properties of the coatings. The most commonly used indenter for scratch testing is the conical Rockwell diamond indenter. However, when the scratch test is performed on the soft polymeric coating deposited on a brittle substrate such as silicon wafer, the conical indenter tends to plough through the coating forming grooves rather than creating cracks or delamination. Cracking of the brittle silicon wafer takes place when the load further increases. Therefore, it is vital to develop a new technique to evaluate the cohesion or adhesion properties of soft coatings on a brittle substrate.

Abrasion Resistance Of Sandpaper Using Tribometer

Abrasion resistance and the effectiveness of sandpaper is often determined by their abrasion performance under different conditions. The grit size, i.e. the size of the abrasive particles embedded in the sandpaper, determines the wear rate and the scratch size of the material being sanded. Sandpapers of higher grit numbers possess smaller particles, leading to lower sanding speed and finer surface finish. Sandpapers of the same grit number made of different materials can behave differently under the dry or wet condition. Reliable tribological evaluation is needed to ensure that the manufactured sandpapers possess desired abrasion behavior under the application conditions. It allows users to quantitatively compare the wear behaviors of different types of sandpapers in a controlled and monitored manner and to select the best candidate for the target application.
