The cutting energy and the rate of removal of the margin in abrasive superfinishing
Russian Engineering Research, 2009A relation is established between the cutting energy in superfinishing, which is a generalized characteristic of abrasive machining, and the removal of the margin, which is one of the basic characteristics of this process. This approach permits effective improvement in abrasive machining.

Hardness of submicrometre abrasive particles and polish rate measurements
Surface Engineering, 1999Metal surfaces (copper and tantalum) and films (copper and tungsten) and silicon dioxide films were polished in deionised (DI) water using submicrometre sized alumina particles of varying density in benchtop Struers and Strasbaugh polishers. The polish rates for copper and tantalum in DI water increase significantly when the abrasive particle density ...

The International Journal of Advanced Manufacturing Technology, 2014
The paper deals with the determination of vibration emission frequency depending on the impact of abrasive particles during cutting of materials. In order to verify the investigated hypothesis, the factor of the abrasive mass flow rate m a = 250 and 400 g min−1 at the traverse speed of cutting head v =

Optimal Abrasive Mass Flow Rate for Rock Erosion in AWJ Machining
2020Erosion process of the Abrasive Water Jet (AWJ) machining on a rock material depends on various parameters. A brittle rock material is removed predominantly by the deformation wear. Abrasive grains can enhance the machining since their hardness and therefore material removal is better than work of pure water.

Blending of agglomerates into powders 1: Quantification of abrasion rate
International Journal of Pharmaceutics, 2010A very common situation in the pharmaceutical arena is that a small amount of cohesive drug substance needs to be distributed in a large bulk of free-flowing filler such as lactose. The key topic of attention is that aggregates of a cohesive drug substance need to be sufficiently broken up in an acceptable time-frame.

Influence of Abrasive Flow Rate on Surface Quality in Abrasive Water Jet Cutting
2009Because of its significant advantages of low thermal influence on workpiece and possibility of cutting different type of materials, the abrasive water jet cutting is more and more present in industry. One of the bigger costs during abrasive water jet cutting is the cost of abrasives.

Effect of the Epoxy-Based Specimen Movement Rate on the Wear Rate in an Abrasive Mass
The conducted experiments have enabled the establishment of a straight-line relationship between wear and testing time; wear intensity therewith changes in a self-organised manner with a decline early in the experiment and subsequent stabilisation. It has been found that the specimen rotation rate during accelerated tests should not exceed 850 min-1 ...Mikhalchenkov, Alexander +3 more
