Axially force limited grinding spindle for robotic grinding
Grinding and Polishing of small parts is often easily performed by human hands, yet is challenging to automate. The grinding and polishing process is best done using a force-control scheme, which human hands perform naturally. Heavy robotic arms, which favor a position-control scheme, are difficult …

Cure Kinetics of Two Part Epoxy Resin and the Effect on Characterization of Thermal Barrier Coatings
… refining gas turbine engines by increasing power and thermal efficiencies while simultaneously reducing cost. Turbine engines operate under high temperatures and therefore thermal barrier coatings (TBCs) composed of yttria-stabilized zirconia (YSZ) play an important role in improving the …

Additive Lithography Fabrication And Integration Of Micro Optics
… the fundamental components in photonic systems and are used to transform an input optical beam into a desired beam profile or to couple the input beam into waveguides, fibers, or other optical systems or devices. Macroscopic optical elements are easily fabricated using grinding and polishing …

Effects of deformations on corrosion of Al-Mn alloys
… deformed layer on the surface as a result of hot and cold rolling. Subsequent heat-treatment precipitates fine secondary intermetallic particles which effect corrosion susceptibility. This work focuses on the effect of surface preparation and deformation on the electrochemical behaviour of Al-Mn …

Development of A closed Loop Control System for Vibration Assisted Grinding
Increasing demand for components made of hard and brittle materials such as glasses, steel alloys and advanced ceramics is such that conventional grinding and polishing techniques can no longer meet the requirements of today’s precision manufacturing community. However, it is essential and much …

Effects of deformation modes on the susceptibility of delayed fracture of advanced high strength steels
… sheet steels (DP780, DP980, TRIP780 and TRIP980). Specimens were strained by either uniaxial tension or bending prior to hydrogen charging and their delayed fracture response was compared with non-deformed samples. Micro hardness testing was performed to assess the effect of …

Vibration assisted machining: Modelling, simulation, optimization, control and applications
Increasing demand for precision components made of hard and brittle materials such as glasses, steel alloys and advanced ceramics, is such that conventional grinding and polishing techniques can no longer meet the requirements of today's precision manufacturing engineering. Particularly, in order …

Advanced image analysis and techniques for degradation characterization of aggregates
Morphological or shape properties of virgin and recycled aggregate sources are known to affect pavement and railroad track mechanistic behavior and performance significantly in terms of strength, modulus and permanent deformation. Under repeated traffic loading aggregate particles used in …

The effect of the cast structure on the evolution of texture during processing of AISI 433 ferritic stainless steel
… AISI 433 i.e. 430 with added Aluminium (Al) and is produced by Columbus Stainless Steel in South Africa. However, these FSSs are inclined to develop surface-roughness defects during cold rolling or forming operations. The surface roughness defects manifest as series of ridges and valleys that …
