Jul 24, 2012· Grinding is an important means of realizing precision and ultra-precision machining. Vibration caused by an unbalanced grinding wheel in grinding process has a significant impact on the quality of workpiece surface. However, the effect of wheel surface topography and/or the relative vibration between grinding wheel and workpiece are not considered in most researches.

Jan 23, 2020· It is also a very valuable tool for permitting to characterize the sensibility of the simulation results to the variation of some settings (e.g., load of grinding media, rotation speed, water addition, etc.) or feed characteristics (e.g., flowrate, sizes, grades, grindability, etc.).

The grinding wheel surface is imported from the fabrication analysis based grinding wheel model of previous work. During each simulation iteration step, it provides the number of contacting grains, contact cross-section area for each grain, and resultant workpiece surface condition.

The application of silicon carbide (SiC) is often limited due to its low machining efficiency and unpredictability about the results of the grinding process. The aim of this paper is to set up finite element analysis models (FEM) about microgrinding process of SiC, to study the change processes about tangential and normal grinding force which can lead to stress and strain inside SiC material ...

Aug 01, 1996· (29) Analysis and simulation of the grinding process. Part II 893 where z%k is the position of grain centre in the wheel co-ordinate system and Az,z is the distance between the two system origins. Figure 12 shows the grinding action of the grain under the combination of the workpiece co-ordinate system and the wheel co-ordinate system.

A newly developed software tool that enables simulation of errors during hobbing and generation grinding can be used for determining and eliminating the causes of deviations in production, thus allowing design engineers and planners to quickly and easily develop new processes and tool designs that can significantly reduce the costs involved in testing.

Nov 03, 2020· Coolants are widely used to dissipate grinding heat in conventional grinding. This process, however, is not satisfactory as coolants often lose efficacy in grinding due to film boiling and can result in adverse health and environment effects. The present paper put forward the concept of a rotating heat pipe grinding wheel, attempting to reduce or eliminate the coolant amount and realize …

The grinding process can be optimized by means of a simulative prediction of the occurring forces. In this paper, a geometric-kinematic simulation coupled with a finite element analysis is presented. Considering the influence of individual grains, an additional approximation to the resulting topography of the ground surface is possible.

This paper proposes a method of modeling and simulation to understand well the process-machine interaction in grinding process of cemented carbide indexable inserts. First, a virtual grinding wheel model is built by considering the random nature of abrasive grains and a kinematic-geometrical simulation is adopted to describe the grinding process.

to note that due to the random simulation of the surface of the grinding wheel, this method is difficult to simulate the grains randomly distributed on the surface of the common grinding wheel [20, 28]. Prof. Tonshoff in the University of Hanover compares the grinding process to …

A more systematic approach, which is an extension of the current FFT-based simulation models, is proposed to approach surface reconstruction. Moreover, the simulation of the surfaces with machining signature by prescribing the parameters, take ultrasonic-assisted grinding as an example, has been taken as the research focus for the first time.
