The finite element model of heavy-duty machine tool’s ram components has a large number of elements, many contact pairs for assembly and a large-scale optimization calculation, which make the optimization difficult to conduct. To solve this problem, a static stiffness optimization method of the large component based on the equivalent elastic modulus is put forward. The proposed method is applied to super-heavy-duty CNC floor-type milling and boring machine of TK6932 as a case study. Based on the principle of the equivalent stiffness, the ram assembly with complex constraints and contacts is eq

A novel amino-functionalized magnetic silica (Fe3O4@SiO2-NH2) was easily prepared via a one-step method integrating the immobilization of 3-aminopropyltriethoxysilane with a sol-gel process of tetraethyl orthosilicate into a single process. This showed significant improvement in the adsorption capacity of anionic dyes. The product (Fe3O4@SiO2-NH2) was characterized with scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray spectrometry, zeta potential and vibrating sample magnetometry. The adsorption performance of Fe3O4@SiO2-NH2 was then tested by remo

The feed quality of a variety of native shrub and herbaceous legume species from the Riverina area of southern New South Wales was determined to provide an indication of their potential use in livestock grazing systems. Fifteen species were sampled from each of two locations (chiefly low fertility roadsides or travelling stock reserves) at four times within a 12-month period viz. August, November, February and May according to the most likely plant parts to be consumed by grazing animals for each species. Digestibility was estimated using an in vitro rumen fluid digestion assay and crude prote

Activin A is a ligand in the TGF-B superfamily that regulates cell proliferation, apoptosis, differentiation, and immune responses. In patients with multiple myeloma, elevated activin A is associated with advanced disease and poorer overall survival (OS). Methods: 60 Metastatic CRPC patients whose serum samples were stored at the Dana-Farber Cancer Institute were used for this study. Plasma activin A levels were measured using ELISA (R&D Systems, Minneapolis, MN). Levels of activin A within key p

BackgroundInterstitial lung disease (ILD) is the most frequent organ involvement in patients with idiopathic inflammatory myopathies (IIMs). Some patients with connective tissue diseases including IIMs may develop a progressive fibrosing (PF-)ILD [1]. The chemokine CCL18 is constitutively expressed by dendritic cells and macrophages in lung tissues and may induce collagen synthesis in lung fibroblasts. Circulating CCL18 correlated with fibrosis severity in idiopathic pulmonary fibrosis and it predicts ILD progression in patients with systemic sclerosis (SSc) [2]. OX40 ligand (OX40L) is a glyco

Tool wear developed in the drilling of carbon fibre reinforced polymer (CFRP) and other FRP composites has been typically attributed in literature to the abrasive nature of the fibres. Unexpectedly, early research conducted by Sandvik Coromant found that the type of resin had an important influence on the tool wear developed in the drilling of CFRP composites with similar carbon fibre fabrics and different resins using coated and uncoated WC-Co tools. This thesis studied the influence of resin on tool wear in the drilling of CFRP composites by investigating the influence of workpiece constitue

This thesis examines some aspects of adaptive control and machine monitoring for Computer Numerically Controlled (CNC) lathes. The design and implementation of a distributed, axls-partioned, multi-microprocessor based CNC system is described in Chapter 2. This CNC system, retrofitted to a lathe, has been developed specifically as a test-bed for research into advanced control and machine monitoring techniques. Chapter 3 is a survey of adaptive control and monitoring techniques for machine tools in general. The next three chapters are devoted to the parameter adaptive control of feed force. Chap

The aim of this work was to identify methods for the production of patient-specific biomedical devices via indirect additive manufacturing (AM) methods. Additive manufacturing has been shown to provide a good solution for the manufacture of patient specific implants, but in a limited range of materials, and at a relatively high cost. This research project considered what are known as “indirect” AM approaches, which typically consider AM in combination with one or more subsequent processes in order to produce a part, with a maxillofacial plate and mandible resection used as a demonstrator appli

Additive manufacturing (`3D printing') techniques provide engineers with unprecedented design freedoms, opening up the possibility for stronger and lighter component designs. Such designs can be developed using structural topology optimisation, a method that computationally designs minimum mass components. Whilst many methodologies now exist this thesis focuses solely on a method known as layout optimisation where components are designed to meet a static strength target using a minimal amount of material. Although layout optimisation offers several advantages over the more predominant topology

High power ultrasonics is currently under-utilised as a manufacturing technology. The potential of the technology in areas such as welding, fastening and cutting has not been fully realised because the beneficial mechanisms available in ultrasonic systems are not always understood and therefore are not fully utilised. The empirical approach to much of the design process often results in unreliable operating performance in customised tools. The aim of the research reported in this thesis, is to develop a structured approach to the design and optimisation of high power ultrasonic systems. Furthe

Rotary planing is one of the most valuable machining operations in the timber processing industry. It has been established that cutting tool inaccuracy and forced vibration during the machining process are the primary causes of surface quality degradation. The main aim of this thesis is to design a control architecture that is suitable for adaptive operation of a wood planing machining in order to improve the quality of its surface finish. In order to achieve the stated goal, thorough understanding of the effects of machine deficiencies on surface finish quality is required. Therefore, a gener

Machining is one of the most important operations in many industrial environments. To prosper in today's competitive industrial world any machining system should be able to deliver the highest possible quality at the lowest possible costs, with very high reliability and flexibility. To fulfil these requirements the idea of e-Monitoring an industrial process was introduced by the Intelligent Process Monitoring and Management (IPMM) Centre at Cardiff University. It has considerable potential applications in industrial systems to not only monitor the health of the machines but also for data manag

Achievable cutting distance of a diamond tool during turning is finite and is a limiting factor in the size of component that can be turned. This limit is particularly problematic when attempting to turn brittle materials, such as those used in infra-red optics. Natural diamond tools have been used for this application. However natural diamond introduces problems: the gems can contain possible contamination with a range of impurities and strong residual stresses from formation. Cutting distance is therefore inconsistent when using natural diamond. Industry is keen to increase possible cutting

Spiral jet milling is a size reduction process used in various industries, ranging from paints to food and pharmaceuticals. It has great benefit in the pharmaceutical industry due to its ability to reduce particulate solids to micron sizes and narrow size distributions. Despite its heavy usage, the underlying size reduction mechanism of the mill is not well understood. However it is generally known that the milling behaviour is dependent on the grinding conditions of the mill, as well as the materials physical and mechanical properties. The system is also very energy inefficient. In this work
