“…The non-contact measurement method of the ZeGage™ optical profiler is used to quantify the three-dimensional shape of the workpiece and measure the surface roughness. The high-resolution graphic sensor enables fast measurements in a matter of seconds and gives excellent imaging of surface details[32].From the various indices in regression Equation (7), it can be seen that the factor that has the greatest effect on blade belt grinding is abrasive grit size, followed by grinding pressure and belt line speed.The results of the orthogonal experiment, Table3, were taken into Equation (7) to produce predicted values of surface roughness and the relative error between the experimental and predicted values was calculated, as shown in Table8below.Figure7shows the comparison between the experimental and predicted values of surface roughness. It can be seen that the relative errors of surface roughness for numbers 4 and 10 are large, 10.8% and 21.62%, respectively.…”

As a high-performance and difficult-to-machine material for the manufacture of blades, titanium alloys are increasingly being used in high-end manufacturing industries such as aerospace and aircraft. As engineering applications become more demanding, so do the requirements for precision. However, to date, the choice of blade grinding parameters is still mainly dependent on the traditional “trial cut” and “experience” method, making the processing efficiency low and the quality of processing difficult to be guaranteed. In order to achieve the requirements of high precision and low surface roughness of the workpiece, to get rid of the status quo of relying on manual decision-making, and to achieve reasonable prediction and control of surface quality, this paper proposes to establish a theoretical prediction model for surface roughness of titanium alloy by abrasive belt grinding, and to analyze the influence of the main process parameters on surface roughness during the grinding process through experiments. A theoretical prediction model for surface roughness was developed. The experimental results show that the model has certain accuracy and reliability, and can provide guidance for the high-precision prediction of the surface roughness of ground titanium alloy blades, which has strong practical significance in engineering.

“…The worn surface morphology of the wheel rings primarily presents peeling, adhesive wear, and fatigue cracks, while the worn surface morphology exhibits the combination of spalling, furrow wear, peeling, fatigue cracks, and various degrees of adhesion. Liu et al [17] investigated the influence of grinding pressure on the removal behaviors of rail material in passive grinding by using a self-designed passive grinding simulator. Pereverzev et al [18] developed a mathematical model for the grinding force in cylindrical plunge grinding, and the grinding conditions, size of the flank wear land areas formed on the grinding wheel cutting grains, properties of the work material, and the geometrical parameters of the grinding tool and work surface are considered.…”

The peripheral surface of the grinding wheel can grind the rail according to the envelope of the contour of the rail surface, thus a fuller and smoother rail surface can be obtained. Specifically, a better grinding effect can be obtained in that the end face of the grinding wheel deviates from the longitudinal section of the rail at a certain angle. Based on the traditional grinding technology theory, the mathematical models of the peripheral grinding parameters (kinematic contact arc length, wheel-rail grinding contact area, and maximum undeformed chip thickness) and the grinding force are established, in which the angle exists between the grinding wheel end face and the rail longitudinal section. The main influence of grinding wheel circumferential speed, grinding wheel kinematic speed, and the deflection angle of the grinding wheel end face on the grinding parameters and the force are analyzed. The result shows that: when there is angle θ in the models, the ratios of peripheral grinding parameters between up-grinding and down-grinding varies monotonically with the increase in vm, and their maximum variation range is about 12%, vs has the greatest influence on the peripheral grinding parameters, and the maximum variation range of the ratios is about 20% when the vs is 10 m/s. With the increase in the grinding width, Fa’ cannot be ignored and will increase gradually with the increase in angle θ. The analysis and conclusion have guiding significance for the structural design, grinding control strategy, and experimental research regarding rail curved surface grinding equipment.

“…However, grinding wheels are typically required to grind rails at high grinding pressures, and environmental protection concerns prohibit the use of coolants during rail grinding [7,8]. In consequence, rail grinding wheels are frequently subjected to extreme grinding squeezing, grinding impact behavior, and high grinding temperatures when grinding rails [9,10]. In light of the aforementioned considerations, the phenolic resin binder for preparing rail grinding wheels has to possess excellent mechanical and thermal stability to ensure the performance of the rail grinding wheels.…”

A scheme for manufacturing heavy-duty rail grinding wheels with silicone-modified phenolic resin (SMPR) as a binder in the field of rail grinding is presented to improve the performance of grinding wheels. To optimize the heat resistance and mechanical performance of rail grinding wheels, an SMPR for industrial production of rail grinding wheels was prepared in a two-step reaction using methyl-trimethoxy-silane (MTMS) as the organosilicon modifier by guiding the occurrence of the transesterification and addition polymerization reactions. The effect of MTMS concentration on the performance of silicone-modified phenolic resin for application in rail grinding wheels was investigated. The molecular structure, thermal stability, bending strength, and impact strength values of the SMPR were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and mechanical property testing, and the effect of MTMS content on the resin properties was investigated. The results indicated that MTMS successfully improved the performance of the phenolic resin. The thermogravimetric weight loss temperature of the SMPR modified by MTMS with 40% phenol mass at 30% weight loss is 66% higher than that of common phenolic resin (UMPR), exhibiting the best thermal stability; in addition, its bending strength and impact strength were enhanced by approximately 14% and 6%, respectively, compared with those of common UMPR. This study utilized an innovative Bronsted acid as a catalyst and simplified several intermediate reactions in the conventional silicone-modified phenolic resin technology. This new investigation of the synthesis process decreases the manufacturing cost of the SMPR, liberates it from the restrictions of grinding applications, and enables the SMPR to maximize its performance in the rail grinding industry. This study serves as a reference for future work on resin binders for grinding wheels and the development of rail grinding wheel manufacturing technology.
