Virtual Truing and Dressing of Grinding Wheel

Abstract

Truing and dressing are essential processes of grinding wheel preparation. They make the wheel geometry true with respect to its rotational axis and its cutting surface sharp. These factors significantly influence the quality of the final profile and surface produced from the grinding process. Prediction of the optimum wheel surface for grinding, defined as one which produces an accurate profile and cuts most efficiently can greatly minimize the time to optimize grinding wheel performance. This paper describes virtual dressing and truing operations, takes under account vibration of the dressing apparatus and shows how to generate wheel surface replica under different conditions.

Multi Criteria Optimization Approach for Dressing of Vitrified Grinding Wheel

“…Klocke and Linke [15] developed a FE (finite element) model for grinding wheel and showed how the wheel wear is affected by different dressing parameters. Bzymek [16] developed a virtual dressing and truing operation model considering vibration of dressing apparatus. In this model, a user is allowed to define the diamond profile of the grit and the virtual model generates the windowed profile of the grinding wheel surface and surface roughness value.…”

Visualization of 3D Topography of Grinding Wheel Surface Dressed by Rotary Diamond Dresser

“…The dressing of a vitrified grinding wheel using an RDD can be considered as a type of cutting process in which a composite of abrasive grits and vitrified bonds is cut by a diamond milling cutter, and the transferability of the cutting path remarkably affects the topography of the working surface of the grinding wheel. However, in the dressing process using an RDD, it is uncertain whether or not the diamond grits come in contact with the entire working surface of the grinding wheel, known as complete dressing [1,2,3]. Our group [4] previously analyzed the kinematic mechanism of dressing using an RDD and developed a two-dimensional computer-aided simulation to visualize the dressing trajectories formed on the surface of the grinding wheel.…”

Vibrations Representation in Grinding Wheels’ Virtual Truing and Dressing Model

“…[6], Chen and Rowe [7]. One of the first applications of advanced computer capability to simulating the grinding process with three dimensional approach is reported in the literature as having been done by Duzy [5] and Bzymek et al [8]. Besides the virtual modeling of truing and dressing results that are covered extensively in [8] in this paper graphics results obtained from a vibration study done using the virtual model are discussed.…”

“…This paper provides additional results to those was reported in [8] taking into account the influence of vibrations. It is a companion paper to [8].…”
