Explosive Forming is a manufacturing technique that uses explosions to force metal into dies and molds.
The explosives are typically either detonated underwater or in direct contact with the materials.
The technique is useful for short production runs of conventionally difficult-to-manufacture parts.
In Explosive Forming a punch or diaphragm in conventional forming is replaced by an explosive charge.
Chemical energy from the explosives is used to generate shockwaves through a medium (mostly water), which are directed to deform the workpiece at very high velocities.
Increasing die life, reducing rejections by the use of japanese cold welding ...Srikar Shenoy
1. Die, mould and tool wear are major reasons for production downtime and increased costs in most industries. Apart from using suitable alloy steels for making dies, a few effective treatments like nitriding, PVD & CVD can be administered to increase die life. Such treatments are not feasible for all metal forming units. Carbide coating to protect only the wear-prone areas of dies using Japanese cold-welding technology is a practical and economical technique that has proven to increase die life. This technique, though similar to welding, does not need pre and post-weld heat treatment and skilled labour. The process does not emit smoke. It can also be carried out on the die or tool without unloading it from the casting press or such equipment, without need of a weld shop.
2. Die spray units are used to effectively spray lubricant on the dies. During the pressure die casting process, it is mandatory to keep die and plunger well lubricated. Die protective coating cum lubricant is used to achieve these objectives. Until recently, pressure feed tanks have been used to spray-lubricate dies. However, these conventional pressure-feed tanks are proving to be a hazard on the shop floor. Pressurised equipments on shop floor always pose a risk of explosion. They also cause production downtime during re-filling. Better alternatives are now available for dispensing die lubricants.
This presentation focuses on basics of solid state processes and its processes including the applications of specific processes. It also covers the advantages and disadvantages of the discussed processes.
This PPT contains information about basic operations of Powder Metallurgy(PM). it is consist of manufacturing techniques of powder, and manufacturing of products by the powder.

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer or a die. Forging is often classified according to the temperature at which it is performed: cold forging, warm forging, or hot forging

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

4. Categories of Manufacturing
Three basic categories of manufacturing processes are:
– Forming processes.
– Machining processes.
– Assembly processes.
5. Forming Process are:
Casting : Pouring metal into the mould.
Forging : Metal is heated & desired shape is given
by pressure.
Extrusion : Forcing metal through dies.
Stamping : Cold working process with the use of
dies.
Embossing & Coining : Metal is stretched.
Spinning : High speed lathe machine is used.
