A computer-aided simulation was developed to visualize the three-dimensional topography of a grinding wheel surface dressed by a rotary diamond dresser (RDD), and the effects of up-cut and down-cut dressing on the roughness of the dressed surface were examined to demonstrate the effectiveness of the simulation. In the case of single-pass dressing, the roughness of the grinding wheel surface decreased with decreasing dresser feed rate and approached a constant value depending on the velocity ratio of the RDD to the grinding wheel. In the case of multipass dressing, up-cut dressing provided the grinding wheel with a surface topography which was much more stable than that provided by down-cut dressing.

Actual Depth

The surface of a grinding wheel dressed by a diamond rotary dresser was generated by computer-aided simulation for the case of multipass dressing on the assumption that the grinding wheel is a homogeneous solid body and the dressing trajectories of the diamond grits are perfectly copied on the grinding wheel surface. The dressing process was visualized as a contour map of the dressed surface profile and the effects of the dressing strategy, i.e., down-cut dressing or up-cut dressing, on the grinding wheel removal process were investigated. It was found that the diamond grits remain the residual depth of cut on the surface of the grinding wheel, resulting in an actual depth of cut larger than that given by the rotary dresser.

A 3D profiler based on scanning white light interferometry with a lateral sampling interval of 0.11μm was introduced to measure the surface topography of a #3000 diamond grinding wheel, and a large sampling area could be achieved by its stitching capability without compromising its lateral or vertical resolution. The protrusion height distribution of diamond grains and the static effective grain density of the grinding wheel were derived, and the wheel chatter and the deformation of the wheel were analyzed as well. The study shows that the grain protrusion height obeys an approximate normal distribution, the static effective grain density is much lower than the theoretical density, and only a small number of diamond grains are effective in the grinding process with fine diamond grinding wheel. There exists waviness on the grinding wheel surface parallel with the wheel cutting direction. The cutting surface of the grinding wheel is not flat but umbilicate, which indicates that the elastic deformation at the wheel edges is much larger than in the center region.

Dimensional Simulation

Simulation of wheel surface topography is one key aspect of modeling the grinding process. A three-dimensional wheel topography model not only makes the simulated wheel topography more close to the real situation, but also benefits evaluation of wheel machinability and wears condition. This paper presents a physical model for simulation of three-dimensional wheel surface topography. Wheel structural components, grain shape, angle distribution of cutting edges, and the binding materials are considered in the model. Feasibility of the model is indicated by the simulation examples.

Design Variables

The grinding wheel surface topography after dressing is an indicator of the effectiveness of dressing operation and, thereby, the effectiveness of grinding as a whole. During dressing, the dresser travels the grinding wheel surface several times so that the dresser grits could hit all most all points on the circumference of the grinding wheel. But the same point should not be hit several times by the dressing grits. This study describes a method and tool for visualizing the grinding wheel surface topography for multiple passes of rotary diamond dresser. Using the proposed visualization method and tool, one can determine the effectiveness of certain dressing conditions beforehand. In addition, the visualization tool can be used for optimizing the design variables of a rotary diamond dresser.

Three Dimensional Measurement

It is very important to measure a grinding wheel surface topography. Therefore a three dimensional measurement system of grinding wheel surface with image processing has been proposed. This system can evaluate a variety of the wheel surface topographies. For example, a histogram of the area or the shape of cutting edges and the distribution map of every shape of cutting edges were obtained. In this paper, a three dimensional model of the cutting edges and a correlation between the state of the wheel surface and grinding mark on the workpiece are reported and the effectiveness is evaluated through an experiment.

Grinding Wheel Topography

The topography of the grinding wheel has a profound effect in analysis and predicting the finished surface roughness. In this paper, the statistical analysis is applied to establish a distribution function of the grain protrusion heights, and the 3-D simulating topography of grinding wheel will be identified. Through experiments, the generated grinding wheel topography is effective in predicting the finished surface roughness.
