In this paper, the system stiffness field model and three-dimensional force ellipsoid are proposed and constructed. In particular for the five-axis NC machining centre, the corresponding sampling points are set on the workpiece surface by applying the matrix operations to the multibody deformation theory. Moreover, an integrated stiffness field of the processing system is developed via different tool spatial gestures. It is concluded from the experiment that the stiffness of the blade top is weak with strong vibrations and low machining precisions, which means deformations could easily arise in this region and influence the machining precision significantly. Ultimately, the blade processing techniques could be developed to minimise the machining error. [Submitted 25 December 2016; Accepted 24 October 2017]","PeriodicalId":154059,"journal":{"name":"Int.

Open voltage, pulse duration and pulse duration were considered as input factors. The numerical models of MRR and SR were established and the ANOVA analysis of MRR and SR were also conducted, showing that the models could be used to predict the experimental results effectively. For obtaining higher MRR and lower SR, the multiple response method was used to optimise the processing parameters. The optimal processing parameters were 85 V, 2329.91 pF, 13.06 μs respectively for open voltage, discharge capacitance and pulse duration. Ultimately, the meso gear was machined by micro wire-EDM using the optimal parameters, showing better machining quality.

It is widely applied in the field of automobile and die manufacturing field. In order to get a reasonable cutting plan, the influence of cutting parameters on milling force and temperature is explored in the process of high speed milling of hardened steel. High speed milling experiment with different machining parameters is carried out and centre composite response surface method is applied. The regression model of cutting force and cutting temperature are established in the process of high speed milling of hardened steel. The significance of the milling parameters on the force and temperature under the interaction and its reasons are analysed. Analysis of variance is performed to evaluate the significance of regression. It can effectively predict the milling force and milling temperature in the process of high speed milling of hardened steel. It provides the basis for the reasonable choice of cutting parameters. From the processed surface quality to verify that cutting parameter is selected based on prediction model and the significant analysis of milling force and temperature is more reasonable.

To this purpose, a wide range of positioning strategies had been studied to reduce interference between the cutting tool and the surface. Indeed, modelled ruled surfaces are non-developable meaning that they cannot be machined without interference. In order to minimise such interference, the positioning strategies studied tend to become increasingly complex, involving software programming using a dedicated language. To simplify matters and apply developed methods using standard software applications, it is proposed here to reduce interference by breaking the machined surface down into a number of sub-surfaces. The aim with this decomposition is to reduce the twist on each portion. A study of the global twist is presented showing nonlinearity with the length of the rule so that cutting methods can be demonstrated.

More than 30% of consumption in nuclear industries is super alloy. A number of holes are required to be drilled into super alloys for their final stage assembly. During conventional machining process, excessive heat is generated, which is the cause of heat treated zone that further affect the life and performance of the product. To overcome this difficulty, a rotary ultrasonic machining method came into existence to machine super alloys by hybrid cutting action (vibratory and rotary) of diamond impregnated core drill. This study focuses on the machining characteristics of super alloy by RUM process. The empirical modelling of process parameters of RUM is carried out for super alloy (Inconel 718) using an experimental design approach called response surface methodology. Material removal efficiency of RUM and surface topography of the machined material are studied. The results reported that for quality and productivity aspect, the feed rate in RUM is found a most critical factor.

The aim of this approach is to use data mining techniques in order to explore, analyse, and extract knowledge from solutions for single machine scheduling problems. A hybrid genetic algorithm coupled with dispatching rules from literature is proposed to find near-optimal solutions for the single machine problem with total weighted tardiness. Using these solutions, data mining extracts knowledge which is then employed along with three proposed heuristics to solve unprecedented problems. The experiments show the superiority of the proposed approach over other well-known dispatching rules, mimicking the genetic algorithm behaviour while retaining heuristics' advantages, i.e., reduced required processing time, reactivity in dynamic scheduling, and real-time scheduling.

The objective of the present work is to analyse the process parameters and to study the effects and optimise the process in order to produce high quality gears. The experiment was conducted in wire EDM machine by full factorial design of experiments having 64 numbers of combinations. Titanium was taken as the work-piece material with brass as the tool electrode and distilled water as dielectric. The experiment was carried out by taking three process parameters at four different levels each. Four response parameters, i.e., MRR, kerf width, wire wear rate and tooth width error (TWE) were obtained from the experiment and the outputs were optimised by using the hybrid approach to get an optimum setting from these combinations. The optimum settings obtained endorses to produce high quality gears in near future.

A cost equation based directly on the losses during manufacturing, such as rejection rate, stops and waste of workpiece materials, also provides a valuable aid in giving priority to various development activities and investments. The present work concerns how a cost model presented earlier for calculating part costs can be developed to describe part costs as a function of the cutting data and tool life time T selected. This enables a tool life model to be a directly integrated into the cost model by use of tool engagement time. The model presented also takes into account the part costs for scrap incurred in connection with forced tool changes. Examples are also given of how the model developed can be used in the economic evaluation of various cutting tools and workpiece materials.

Experimental study using full factorial design of the electrode force, welding current, welding time parameters was conducted. In order to identify the effects of each factor and their interaction, the artificial neural network was employed. The R2 equal to 98.11% of the model confirmed the effectiveness of the ANN model for describing the correlation between the welding parameters and joint strength. It was observed that the welding current was the most influential process parameter on the joint strength and in return the welding time had the least influences. Interaction between the welding parameters occurred only at very high welding currents. It was observed that the ANN model provides a lucrative reference for RSW strength characterisation of Inconel alloy 625.

Chatter occurs as a dynamic interaction between the tool and the work piece resulting in poor surface finish, high-pitch noise and premature tool failure. In this paper, the chatter prediction is done by active method by considering the parameters like spindle speed, depth of cut, feed rate and including the dynamics of both the tool and the workpiece. The vibration signals are acquired using an accelerometer in a closed environment. From the acquired signals discrete wavelet transformation (DWT), features are extracted and classified into three different patterns (stable, transition and chatter) using support vector machine (SVM). The classified results are validated using surface roughness values (Ra). [Received 12 August 2016; Accepted 19 May 2017]","PeriodicalId":154059,"journal":{"name":"Int. J. Manuf.
