Practical pin tooling
A high resolution reconfigurable mold has been sought after for over 150 years. An ideal reconfigurable mold would be capable of producing detailed surfaces for use in molding and be capable of fast surface reconfiguration. Such a device would combine the fast speed and repeatability of formative …

A global sourcing strategy for durable tooling
… develops a global sourcing strategy for durable tooling and a methodology to help firms determine the best sourcing alternative for indirect materials. A low cost sourcing study done at Carrier compares the landed cost and quality of sheet metal stamping dies sourced from both China and the U.S. …

Enhanced use case map analysis and transformation tooling
The Use Case Map (UCM) notation enables the use of graphical scenarios to model greybox views of a system's operational requirements and behaviour. The scenario traversal mechanism is the most popular UCM analysis technique as it allows modellers to test, explain, and transform UCM models. However, …

Enhancing hot tooling to forge high-γ ′ superalloys
… minimised cracking per part). Widely applied hot tooling materials like hot work tool steels or Molybdenum alloys are severely restricted above 500 °C. The recent considerations of IN718 hot dies for Ti forgings discouraged the use of the alloy above 650 °C. This research investigates the …

A simulation study of tooling effects in automated manufacturing.
… The effects of shared and dedicated tooling policies have also been investigated. With the comparison of performance measures for each set of operational strategies, the mutual advantages and concerns of each of them are highlighted. Within the simulation scope, the shared tooling …

Tooling techniques in Romanesque illumination: appearance, transmission, and implications
This dissertation offers proof that tooling was not a new phenomenon of thirteenth century Gothic illumination, as has up until now generally been believed, but was part of a well established technical tradition in twelfth century manuscript decoration. Gold surfaces are tooled with metal …

Rapid tooling by integration of solid freedom fabrication and electrodepostion
Rapid tooling (RT) techniques based on solid freeform fabrication (SFF) are being studied worldwide to speed up the design-production cycle and thus keep manufacturers at a competitive edge. This dissertation presents a novel rapid tooling process that integrates SFF with electrodeposition to …

Tooling performance in micro milling: Modelling, simulation and experimental study
… limited and comprehensive studies on the micro tooling performance are essential and much needed particularly for the process planning and optimization. The cutting performance of micro tools is largely dependent on the dynamic performance of machine tools, tooling characteristics, work material …

Independent innovation through digital fabrication focusing on explorations in reconfigurable pin tooling
… fabrication concept known as Reconfigurable Pin Tooling (RPT). This manufacturing idea has also been described as ‘universal’ or ‘ideal’ tooling and has attracted interest from a number of researchers and inventors since the mid nineteen century (Munro and Walczyk, 2007). Although presenting …

Infiltration stop, epoxy tooling development, and shrinkage studies in three dimensional printing
… can not only fabricate prototypes but functional tooling as well. In the process, a thin layer of powder is spread onto a powder bed to which a printhead delivers the binder that selectively joins the particles. Successive layers are printed and thus a 3-D object is constructed. In the case of …

Advancing Ubiquitous Tactile Sensing through Comprehensive Tooling for Resistive Matrix-Based Sensors
Resistive matrix-based tactile sensors offer a scalable and intuitive approach to capturing human-environment interactions, yet deploying them in real-world systems remains challenging because they must remain portable, adaptive, and long-lasting. This thesis presents the WiReSens Toolkit, an …
