An iterative numerical approach to evaluate the variable friction coefficient of steel AMS5643 using ring compression tests (2023)
Journal Article

The coefficient of friction is an important variable that must be defined to allow the accurate prediction of the forming geometry and stresses involved in metal forming processes. Literature reports have shown that the coefficient of friction does n...

A methodology to support robotic polishing of moulds integrated with CAD/CAM (2023)
Journal Article

Typically, the final process in the manufacture of molds is mechanical polishing, a process predominantly conducted manually. This is an important process step to improve the surface quality of the mold without affecting the geometry of the cavity. C...

Numerical shape, thickness and stacking sequence optimisation and experimental study of hybrid composite plates under in-plane shear loading (2023)
Journal Article

Shape, thickness and stacking sequence optimisation of a damage tolerant hybrid (GFRP-CFRP) composite laminate is performed using the commercial Optistruct solver. The results of the optimisation study are compared to both a benchmark non-damage tole...

An experimental investigation of the impact response and post-impact shear buckling behaviour of hybrid composite laminates (2023)
Journal Article

This paper investigates the effect of transverse impact loading on the in-plane shear behaviour of two laminate configurations. The extensive experimental studies consider a pure carbon laminate (type 1) and a novel X-shaped carbon/glass laminate (ty...

GA-AHP Method to support robotic polishing process planning (2022)
Journal Article

The finishing stage of mould manufacturing is generally completed via mechanical polishing, manual conducted. Not only is this the most expensive phase of the process but also is currently struggling with a deficit of skilled workers. To address thes...

Design, novel quality check and experimental test of an original variable length stepped scarf repair scheme (2021)
Journal Article

The performance of well-established stepped scarf repair schemes for highly loaded composite structures has been studied in previous works. However, none of the proposed repair schemes appear to minimise healthy material removal. Thus, this paper pro...

Model-based information navigation for engineering documents (2020)
Journal Article

Engineering and the manner in which engineers think is largely visual and functional, and yet engineers are typically provided with search engines that are text-based. While software based on a visual and functional ethos exist (CAD for example), whe... Read More about Model-based information navigation for engineering documents.

Towards collaborative robotic polishing of mould and die sets (2019)
Journal Article

Dies and moulds are fundamental elements in the manufacturing of a wide variety of products. The surface polishing of dies and moulds with complex features largely relies upon time-consuming manual work of skilled workers and, as a result of the dimi...

Bio-inspired design to support reduced energy consumption via the ‘light weighting’ of machine system elements (2015)
Journal Article

A potential technique to reduce the energy required to actuate moving parts in a machine is to reduce their mass. This paper presents initial research attempting to answer this question for robotic arm application using a biologically inspired approa...

Environmental auditing of a packaging system for redesign: A case study exploration (2014)
Journal Article

Within the United Kingdom a significant portion of the energy consumed each year is done so through industry. It is therefore desirable to take measures that reduce this consumption. A process common to all manufacturing sectors is that of packaging,... Read More about Environmental auditing of a packaging system for redesign: A case study exploration.

An empirical investigation into the influence of sealing crimp geometry and process settings on the seal integrity of traditional and biopolymer packaging materials (2013)
Journal Article

This article presents the results of investigations to determine how process settings and crimp geometry affect the seal strength and integrity of traditional polyolefin and biopolymer flexible packaging materials. The results show agreement with pre...

Modelling the material flow and web tension in the vertical form-fill-seal packaging process (2011)
Journal Article

Vertical form-fill-seal (VFFS) machines are widely used to form bags for packaging products such as confectionary and snack food. One critical component of the machine is the forming shoulder, which needs to manipulate, without damage, the packaging...

Capturing constraint evolution: A technique to preserve and handle design knowledge (2011)
Journal Article

Product development can be considered as the evolutionary and iterative process of recognition, formulation and satisfaction of constraints. These become the rationale driving the design to the final specifications, with the evolution of constraints...

The implementation of a direct search approach for the resolution of complex and changing rule-based problems (2011)
Journal Article

During the evolution of constraint modeling approaches, they have increased in their ability to resolve more and more complex problems. They all rely upon their ability to define the design problem by a set of constraint rules, which are true when th...

Using constraints at the conceptual stage of the design of carton erection (2010)
Journal Article

Cartons are a common way to package many consumer goods. If new designs are used it is necessary to simulate their erection to ensure that this works correctly, particularly at high speed. In this paper, constraint-based techniques are used to model... Read More about Using constraints at the conceptual stage of the design of carton erection.

The barriers to realising sustainable process improvement: A root cause analysis of paradigms for manufacturing systems improvement (2010)
Journal Article

To become world-class, manufacturing organisations employ an array of tools and methods to realise process improvement. However, many of these fail to meet expectations and/or bring about new less well understood problems. Hence, prior to developing...

Constraint-based simulation of carton folding operations (2010)
Journal Article

Cartons are a common means for packaging a variety of items. These are usually "erected" by dedicated machines which fold the carton into shape from a flat net. When there is a need to use new forms of cartons, dedicated machinery may not be appropri... Read More about Constraint-based simulation of carton folding operations.
