Development and Application on the Grinding Process Modeling and Simulation

Abstract

：The research of the grinding process modeling and simulation is presented. The development progress and its tendency of three types of modeling methods and simulation are described results, which are based on empirical analysis, theoretical analysis and finite element technology. The method of modeling and simulating results are discussed respectively in detail. Meanwhile the limitations of application of models are analyzed. It is indicated that the empirical models are based on finite data of experiments, which have low level of prediction abilities, the theoretical models which are set up on ideal assumption is complexity, and the finite element models are restricted to analyze the process of single-grit grinding due to technical problem, on that account, the methods of grinding process modeling and simulation research based on the regular abrasive distribution grinding wheel are introduced. Furthermore, their present situation prospect and significance for prediction, optimization and control of high speed and high efficiency grinding are elaborated.

Morphology Analysis and Characteristics Evaluation of Typical Super Abrasive Grits in Micron Scale

“…The proper mean of AR (0.71) as shown in Fig. 9, c, is ideal and optimal for practical manufacture process to improve the holding force distribution of the diamond abrasives [5,6]. Meanwhile, most of the grits with bulky and unbroken edges, which induce block shear behaviour, are beneficial to achieve smoother workpiece surface roughness, less clogging and abrasive grit wear.…”

“…In many previous researches on grinding dynamics, the shapes of abrasive grits are commonly assumed to be either individual cone or pyramid with designated angles, even simplest sphere, or ellipsoid [1,3,5,6] for solid grit modelling and grinding simulation to analyse elastic-plastic deformation and stress-strain distribution in material removal. In fact, the actual grits distributed on the circumference of abrasive tool are not exactly same even far away from aforementioned geometrical assumption in grinding.…”

Quantitative impacts of regenerative vibration and abrasive wheel eccentricity on surface grinding dynamic performance

“…By combining and integrating Equations (1)-(3), (10) and (12), instantaneous grinding force acting on single grit 'A' in down grinding process are obtained. Then total grinding force in given per rotational period will be summed up as shown in Equation 13 by accumulating the force from each active individual kinematic grit that is effective in abrasive grit-material interaction zone to remove material.…”

“…It has been generally accepted that the material removal during the engagement of an abrasive grit with the workpiece material has three phases, i.e. rubbing, ploughing and cutting [1,4,5,6,10,11]. By increasing cutting depth of grits, the material removal is more effective due to the increased cutting actions in the engagement of grits and workpiece [5].…”

A new method for optimizing process parameters of active measurement grinding based on grey target decision making

“…Along with the advent of new materials, new tools, and new technologies, the application models of grinding analysis are also innovating. 5 Many experts and scholars have analyzed some of the factors in the grinding process by various means and have optimized some parameters to improve the grinding quality.
