grinding process interaction

Modeling and simulation of grinding processes based on a

mechanism, a physics-based model is necessary to quantify the microscopic interactions, through which the process output can be correlated with the input parameters. In the dissertation, the grinding process is regarded as an integration of all microscopic interactions, and a methodology is established for the physics based modeling.

Modeling and Simulation of Process-Machine Interaction in

Interaction of process and machine in grinding of hard and brittle materials such as cemented carbide may cause dynamic instability of the machining process resulting in machining errors and a decrease in productivity. Commonly, the process and machine tools were dealt with separately, which does not take into consideration the mutual interaction between the two subsystems and thus cannot

[PDF] Modeling and simulation of grinding processes based

Grinding is a complex material removal process with a large number of parameters influencing each other. In the process, the grinding wheel surface contacts the workpiece at high speed and under high pressure. The complexity of the process lies in the multiple microscopic interaction modes in the wheel-workpiece contact zone, including cutting, plowing, sliding, chip/workpiece friction, chip

Simulation of surface grinding process, part 2

Sep 01, 2005· Although the grinding process has been a topic of extensive research for the last 20 years, a complete understanding of the process has yet to be achieved. It is partly due to the fact that grinding is a stochastic process in that a large number of abrasive grains of random-defined geometry act as a cutting tool. Interaction of the abrasive

grinding a dynamic machining process

Grinding: A Dynamic Machining Process. Grinding is a dynamic process. In a constantly changing environment, the part is ground, the wheel breaks down from use, and thermal issues cause changes in the machine. All of these factors affect the success of CNC grinding, an application that is deemed successful only if the desired results are

Except the grit-workpiece interaction, which is expected to produce chip, the remaining three undesirably increase the total grinding force and power requirement. Therefore, efforts should always be made to maximize grit-workpiece interaction leading to chip formation and to minimize the rest for best utilization of the available power.
