The micro topography of the grinding tool has a considerable influence on the cutting forces and temperature as well as the tool wear. This paper addresses an analytical modelling of the micro-grinding process based on the real tool topography and kinematic modelling of the cutting-edgeworkpiece interactions. An approximate shape of the abrasive grains and their distribution is obtained from the confocal images, which are taken from the tool surface - determining the grain height protrusion and the probability density function of the grains. To determine the grinding forces, a transient kinematic approach is developed. In this method, the individual grit interaction with the workpiece is extended to the whole cutting zone in the peripheral flank grinding operation. Hence a predictive model of cutting forces and surface roughness in micro grinding of titanium grade 5 is developed. Finally, the simulated forces and surface roughness are validated by the experimental results.

The present study alters the temperature characteristics during high-frequency induction brazing of diamond grits and investigates their effects on the properties of the diamond/brazing alloy interface. The high-frequency induction brazing was conducted in a vacuum using Ni-Cr as active filler alloy. An active temperature range was identified for the brazing of high-quality diamond tools. This temperature range, coupled with long heating time, favours the wetting of filler alloy to diamonds, and the chemical reactions and element diffusion at the diamond/alloy interface, but reduces the static compressive strength of the diamonds. If the temperature is slowly raised, the protrusion height and location of brazed diamonds can be more precisely controlled. Brazed diamonds with 30%-50% protrusion are optimal for cutting.

The present work is focused on the wear of the abrasive tools during the industrial polishing process of porcelain stoneware tiles, aiming to extend the validity of using morphological space to quantify the wear when very fine abrasive tools are used. In such morphological space, the horizontal and vertical axes are respectively the skewness (Sk) and the kurtosis (K) of the distribution of heights taken from several surface profiles. Despite the existence of an intrinsic interaction between Sk and K, the approach enables the sequence of geometrical changes suffered by the fickert surface to be quantitatively evaluated. The experimental points obtained were nearly aligned and with a negative slope, just as expected for abrasive wear. Implausibly, the results for fine abrasive fickerts was much more scattered than for those with coarse abrasive particles found in literature.

The influences of hardfacing deposit and deep cryogenic treatment on three-body abrasive wear behaviour of AISI 1013 steel were studied. The three-body abrasive wear tests were carried out using the dry sand/rubber wheel test rig as per ASTM G65 standard. Hardfacing was done by manual arc welding using ZEDALLOY VB hardfacing electrode. The deep cryogenic treatment was carried by using liquid nitrogen temperature at −196°C. The applied load, sliding velocity and sliding distance were considered as process parameters. Experimental results reveal that the hardfacing deposit showed the highest abrasive wear resistance as compared to deep cryotreated material. Worn-out surface observation by SEM witnessed same behaviour. The nature of material removal was microploughing or microcutting depending on the attack angle, due to cracks formed on the surface of material.

The produced chips in the grinding process may load the pores and cavities between the cutting grains. The loading of the grinding tool reduces the amount of the transported coolant to the contact zone and simultaneously increases the induced heath by friction in the cutting zone. Hence, increased grinding forces and temperature, surface roughness and wear of the cutting grains are the consequences of a loaded grinding tool. Infiltration of the grinding tool is one of the effective methods to reduce loading. The effects of infiltration have been studied for the first time in this research on various vitrified bonded grinding wheels with different grain materials, grit sizes, porosity and hardness. Better surface quality and longer dressing intervals are the main results of the infiltration of the grinding tools.

In the present paper, a semi-empirical grinding force model is developed combined with the achievements of previous researchers by composing effects of normal and tangential grinding forces in two main parts respectively: cutting force and sliding force. This model is used to predict the total normal and tangential force in the surface grinding. These force components were expressed in terms of the grinding process parameters such as wheel speed, workpiece feed rate, width of the workpiece and depth of cut. There are four unknown coefficients in each equation which can be determined by experiment results at specific conditions with the variations of grinding process parameters. Four different water-based grinding fluids were tested for different specific grinding conditions. The calculated normal and tangential grinding results are compared with the experimental ones. To have a better agreement with experiment data, shallow grinding condition is chosen to obtain the modified model.

Hybrid machining techniques are becoming more and more popular for machining of difficult-to-cut materials. This paper presents an approach for the optimisation of electric discharge diamond cut-off grinding of Inconel 718 with multiple performance characteristics based on the Taguchi orthogonal array with grey relational analysis. In this study, the machining parameters namely, wheel speed, current, pulse-on-time, and duty factor are optimised for performance characteristics, i.e., material removal rate and surface roughness. The optimal machining parameters are determined by the Grey relational grade as the performance index. The research result identifies significant machining parameters and their effects on process performance. The confirmation experiments have been conducted to verify the optimal process conditions. Experimental results show that the performance of process improved effectively through this approach.

It has been found that wheel wear rate (WWR) and surface finish is adversely affected in order to improve the material removal rate (MRR) in electrical discharge diamond grinding (EDDG) process. Therefore, simultaneous optimisation of above three responses is always desired. This research paper presents the modelling and multi-objective optimisation of EDDG using AI-based hybrid ANN-GA approach. The effect of wheel grit size has also been considered along with electrical parameters such as peak current, pulse-on time and pulse-off time. The significant control parameters for different responses have been found and effect of their variation has been discussed. The developed ANN models for different responses have been found reliable with negligible prediction errors. The optimisation results show considerable improvement of 97% in MRR with marginal increase in WWR and surface roughness.

In this research paper, the effect of abrasive water jet (AWJ) machining process parameters such as jet operating pressure, feed rate, abrasive concentration and standoff distance (SOD) on the surface roughness produced during machining of graphite mixed glass fibre reinforced polymer (GFRP) composite is investigated. Experiments were conducted using Taguchi's L27 orthogonal array design and the process parameters were optimised to obtain high surface finish. Experimental data were analysed using analysis of variance (ANOVA) which shows that the surface roughness decreased by 15.90% and increased by 9.22% for the increase in operating pressure and SOD respectively. Also, regression model is developed to predict the surface roughness and found that the predicted values are in close agreement with the experimental values (error 6.57%).

Based on the magnetorheological (MR) effect, this research proposes a kind of magnetorheological finishing (MRF) in tangential magnetic fields formed by the rotation of magnetic poles in order to achieved realtime adjustment of MR polishing pads. In this paper, monocrystalline silicon was utilised to investigate the plane polishing characteristics based on the magnetorheology in single-point dynamic magnetic fields under different process conditions. Results showed that favourable polishing effects were obtained when silicon carbide abrasive was used to polish the workpieces for 50 to 70 min with the tangential magnetic fields being 5 mm and the machining gap being 1.1 mm. Afterwards, strontium titanate ceramic substrate, monocrystalline silicon and monocrystal 6H-SiC were polished for 50 min using this technology. It was found that the surface roughness Ra of this three materials were reduced from 0.45 to 0.11 µm, from 400 to 7 nm and from 70 to 9 nm, respectively.
