Research Method to Calculate Cutting Force when Longitudinal Feed Centerless Grinding

Fabrication of Microscale Tungsten Carbide Workpiece by New Centerless Grinding Method

New laboratory scale Grinding method to predict energy and the feed grindability of mill of Sarcheshmeh Copper Complex

One of the factors which are usually difficult to be measured in mills is the grindability and distribution of feed under real situation and in a short time. In the condition of achieving a fast and convenient way to determine these parameters, the proper relationship between energy, hardness and particle size distribution can be obtained. Feed hardness is one of the most important factors in g...

Application of Improved BP Neural Network in Controlling the Constant-Force Grinding Feed

BP neural network is applied to control the amount of feed, which is the key problem during the constant-force grinding. Firstly, BP neural network is constructed. Because its convergence is slow and local minimums often occur, the adaptive learning rate is used and certain momentums are added to improve BP neural network. Then the feature parameters in time and frequency domain are picked up i...

Ultrasonic assisted creep feed grinding of Inconel

The paper details the effects of depth of cut and vibration amplitude when ultrasonic assisted (US) creep feed grinding Inconel 718 with an open structured alumina based wheel. The workpiece was actuated at a constant frequency (~20.5kHz) via a block sonotrode attached to a 1kW piezoelectric transducer-generator system. A full factorial experimental array comprising 12 tests was conducted invol...

A novel method to calculate the mechanical properties of cancer cells based on atomic force microscopy.

PURPOSE Mechanical properties, as the inherent characteristics of cells, play a critical role in many essential physiological processes, including cell differentiation, migration, and growth. The mechanical properties of cells are one of the criteria that help to determine whether the tissue contains lesions at the single cell level, and it is very important for the early prevention and accurat...
