The performance of a grinding wheel is greatly determined by its structure which in turn is influenced by the characteristics of the bonding material. Vitrified bonds were used in 50% of the wheels, which are mixtures of clay, feldspar and fusible materials. Vitrified wheels were fired at temperatures >1270°C. The main aim of this work is to focus on the feasibility of a low melting bonding material that would render the wheels a better or comparatively closer performance level than that of the conventional wheels, thereby attempting to reduce fuel and time consumption. Suitable low melting bonds were chosen based on the results of fusibility tests and chemical analysis, and their properties such as density, sound index (SI) and Young's modulus (YM) were evaluated. Performance characteristics were investigated through a cylindrical grinding test and compared along with the standard wheel. Attempts have been made to reduce the size of bonds to improve their properties, and the results obtained were promising.

“…The results feed into a model of the overall grinding process, developed by the authors [20,21]. This model includes a description of the dynamics of the workpiece [22], contact and material removal [17], empirical cutting forces, and grinding wheel topography and wear. Additionally, a temperature model exists that estimates the workpiece temperature through the calculated cutting forces, see Fig.…”

“…With a diameter of =125 mm, the corresponding cutting speeds of =12 m/s, 18 m/s and 24 m/s were used. Based on detailed grinding wheel studies, as described in [17], we have used a superposed eccentricity and waviness of 4 sine waves. Further, the workpiece was modeled as an elastic Euler-Bernoulli beam with a cantilevering length of 100 mm and a diameter of 10 mm.…”

Abstract. The complex dynamics of grinding repeatedly cause critical or unstable process conditions. For a better understanding and prediction of such occurrences, the dominant excitation phenomena need to be identified and their interrelation with the system dynamics have to be analyzed.Based on measurements of the excited frequencies in several operation modes of the grinding machine, the grinding wheel rotation is identified as a major excitation source. Further analysis of the grinding wheel surface displays three main components that define the excitation frequencies of the system; these are the eccentricity, waviness and roughness (also named wheel topography). Moreover, the wheel topography and thus the excitation frequencies can change over time due to excessive wear.Following the experimental results, a grinding wheel topography and wear model are developed and included in an integrated simulation of tool grinding. The analysis of the calculated cutting forces in the frequency domain confirm the excitation due to the grinding wheel topography.Firstly, this work has extracted the grinding wheel as a prominent excitation mechanism and reproduced it with the developed grinding model. Secondly, we have evidence that a complete description of the complex grinding process is only possible when considering the interdependence between system dynamics, wheel kinematics and the grinding process.
