Advanced hard-to-machine materials are difficult to manufacture. This work explores the application of electrical discharge machining (EDM) of Ti-6Al-4V alloy for different pulse parameters. Machining performance is evaluated by material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR). For the experiment, orthogonal array have been found using Taguchi methodology. The optimum parametric settings obtained by grey relational analysis (GRA)-based Taguchi method which was compared with hybrid grey relational-principal component analysis (PCA)-based Taguchi. It was found that GRA-based PCA optimisation methodology results more feasible parametric setting which has also been confirmed by the validation experiments. The rectangular pulse current shape and its duration have found to be significant. The optimum value of process variables were pulse duration of 5µs, duty factor of 11%, peak current of 30 A and gap voltage of 9 V to achieve maximum MRR and lower TWR with better surface finish.

This work streamlines assignment of roughing strategies for complex parts from those that are available on a computer-aided manufacturing (CAM) system. A Pelton hydro-turbine bucket is used as an example, divided into independent regions. For each region the applicable strategies, toolpath types, as well as their individual parameters are examined at a small enough number of discrete levels to ensure practical feasibility. The responses, i.e. machining time and rest material, are combined into a single weighting function. The absolute minimum number of possible scenarios is guaranteed by Taguchi design and the optimum factor levels are determined. Analysis of variance reveals the significance of each factor but also possible omissions of factors and/or interactions that may occur. The approach saves time, is open to rectification by simply adding the missing experiments and is equally applicable to any mechanical component to be machined.

This paper presents an architecture of a computerised numerical controller (CNC) compliant with the ISO 14649 standard (STEP-NC) through an adapter that converts a program in the STEP-NC format to G-code. This architecture attempts to enable the implementation and dissemination of the STEP-NC standard in any company that performs numerically controlled machining operations. The STEP-NC controller is based on the open source LinuxCNC controller, which is compliant with the ISO 6983 standard (G-code). In order to validate the architecture a machine tool was built, having LinuxCNC on a personal computer. The controller is integrated with the STEP part 21 data model (ISO 10303 standard) using an adapter that reads a STEP-NC file generated by a software that models a 3D part via the internet. The LinuxCNC controller runs the STEP-NC file transparently, and the results are shown through a case study with the manufacture of an example part.

In this paper, three dimensional finite element analysis has been carried out using FEM-based DEFORMTM 3D software on hot forging of connecting rod. The influence of design parameters and process parameters are investigated for the responses like effective strain rate and forging load during forging operation. In order to optimise both the responses simultaneously, grey relational analysis (GRA) embedded with Taguchi method is employed. Grey relational grade is used as a performance index to determine optimal setting of process parameters for both the responses simultaneously. Analysis of variance (ANOVA) is employed to determine significant parameters. Process parameters such as flash thickness, flash width, and corner radii are found to be the most significant parameters affecting grey relational grade. Optimal process setting leading to a higher effective strain rate with the least forging load has been verified through a confirmation experiment for validation of the results.

Ultrasonic-vibration-assisted grinding (UVAG), a hybrid machining process combining material removal mechanisms of diamond grinding and ultrasonic machining, has been used to machine various hard-to-machine materials. Large amount of research work on UVAG has been carried out since it is invented. However there are few review papers to cover the current literature on UVAG. The emphasis of this literature review is the experimental investigations of the drilling process with ultrasonic vibration using a core drill with metal-bonded diamond abrasives. Experimental results are summarised and compared. The inconsistent results and their reasons are discussed. Furthermore, directions of future research on UVAG are also presented.

A method of constant grinding force following unknown curve part based on force/torque information is presented in this paper. A new estimation method of the unknown curve normal direction is proposed based on force and torque information. According to the method, the force control and position control directions of the hybrid force/position control can be estimated. The conventional proportion integration (PI) force control method is tested at first. Since the force PI control parameters are difficult to determine, fuzzy PI control is introduced to optimise the force PI control parameters automatically. According to the experiment result, the method can greatly reduce the contact force fluctuation during grinding wheel contact with part contour, and the contact force during estimating curve surface is in the desired range of ± 2 N. And during grinding procedure, the acting force fluctuation is in the desired range of ± 7 N. [Received 20 April 2015; Revised 17 February 2016; Accepted 23 February 2016]

We study serial batching scheduling of deteriorating jobs in a production-delivery supply chain to minimise the total logistics cost. Each job should be delivered to customer within its guarantee period. We define that if a job which is finished before its departure date or delivered to the customer before its due date will incur respectively a work-in-process or customer inventory cost. We first formulate the problem as a general model and prove its complexity in a general way. Then we study a special case of the problem and propose a tabu algorithm for solving it. In order to evaluate the proposed tabu algorithm, we compare it with CPLEX solver for small size problem instances, and with a lower bound for large size problem instances. The results of experiments indicate that the proposed tabu algorithm is efficient for the randomly generated problems in terms of both solution quality and time efficiency.

Customers' special need is one of the key drivers in product configuration design. The complexity of configuration design for large container cranes is known as non-deterministic polynomial-time (NP) hard. We are interested in the fast configuration model and method that support large container cranes configuration. In this paper, a rapid configuration design framework for large-scale container cranes is proposed. A constrained 0-1 programming gene evolutionary model is constructed. We propose an ant colony algorithm-based fast configuration design method. A design example of the cart mechanism is provided to test the validity and evaluate the effectiveness and efficiency of the proposed method, in which performances of different algorithms are compared. Results have shown that the method presented here is able to converge with solutions of good quality. [Received 05 December 2014; Revised 01 July 2015; Accepted 21 September 2015]

Cutting heat is one of the major factors affecting the cutting performance and service life of cemented carbide inserts. During the milling of water-chamber heads, periodic thermal and mechanical loading can lead to failure in round cemented carbide inserts, significantly reducing both their service life and their cutting efficiency. This paper describes high-temperature deformation experiments and analyses of both metallic material and YT15 cemented carbide; by conducting these experiments, we were able to determine the thermal expansion coefficient of the cemented carbide within a certain temperature range, as well as provide suitable parameters for the thermal deformation calculation and cutting simulation of cemented carbide. We then conducted water-chamber head field milling experiments, from which we discovered that failures of the round inserts are generally attributable to wear and fracture. We used the thermal expansion coefficient, material properties of the inserts, and billets and cutting parameters to simulate the process of cutting water-chamber heads (508III steel) with a round insert. In combination with the simulation result, we assessed the influence of cutting force, cutting heat, and insert deformation on insert failure, and we also investigated the insert failure mechanism while cutting water-chamber heads. Ultimately, we were able to analyze the influence of different milling conditions on insert failure. We tested the cutting performances of five types of inserts so as to optimize the insert structure and coating. The results of this research can provide a foundation for improving the anti-failure performance and service life of inserts, which are often used in water-chamber head cutting.

This paper describes a study on efficient optimisation of real-world product sequencing problems with the aim of finding robust solutions. Robust solutions are insensitive to unforeseen disturbances in a manufacturing process, which is a critical characteristic for a successful realisation of optimisation results in manufacturing. In the paper, the traditional method of achieving robust solutions is extended by using standard deviation as an additional optimisation objective. This transforms the original single-objective optimisation problem into a multi-objective problem. Using standard deviation as an additional objective focuses the optimisation on solutions that have both high performance and a high degree of robustness (that is, a low standard deviation). In order to optimise the two objectives simultaneously, a multi-objective evolutionary algorithm based on the Pareto approach is used. The multi-objective method for increased robustness is evaluated using both a benchmark problem and a real-world test case. The real-world test case is from GKN Aerospace in Sweden which manufactures components for aircraft engines and aero-derivative gas turbines. Results from the evaluation show that the method successfully increases the robustness while maintaining high performance of the optimisation.
