Ultrasonic machining (modern manufacturing process)
Ultrasonic machining (USM) uses an ultrasonically vibrating tool to force abrasive particles in a slurry against a workpiece at high speeds. The abrasive particles fracture pieces of the workpiece material through brittle cracking. Common abrasives used are boron carbide, aluminum oxide, and silicon carbide with grit sizes from 400-2000. USM is effective for machining hard and brittle materials like glass that are difficult to machine through other methods. A comparative study investigated the USM of various materials like alumina, zirconia, quartz and glass to understand the effects of intrinsic material properties on machining rates and surface topography.
Abrasive jet machining.51 ppt
Abrasive jet machining is an unconventional machining process that uses a high-velocity stream of abrasive particles suspended in a gas to remove material through erosion. It can machine hard and brittle materials that cannot be cut through conventional processes. The process involves mixing abrasive particles with a pressurized gas and passing them through a nozzle to erode away the workpiece material. It provides advantages like ability to machine heat-sensitive materials without damaging them and capability to cut intricate holes, but has low material removal rates and accuracy issues due to stray cutting.
Step stencils-laserjob
The document discusses challenges and guidelines for printing solder paste with step stencils. It analyzes how factors like squeegee speed, pressure, angle, and material affect the amount of paste residue near step edges. Testing showed circular apertures near steep step downs had lower transfer efficiency than oblong apertures due to more residue. Guidelines recommend reducing speed, increasing pressure, changing the angle to 45°, and using a polymer squeegee to minimize residue for consistent paste transfer. Apertures far from step edges showed high transfer efficiency regardless of geometry or step height.

ABRASIVE JET MACHINING by Ms Shikha Kashyap
Abrasive jet machining uses abrasive particles mixed with air or water that are forced through a nozzle at high velocity to erode material from the workpiece surface. Finer abrasive particles produce better surface finishes down to 0.5 micrometers, but removal rates are very slow at around 0.5 cubic centimeters per hour. The process is suitable for machining hard and brittle materials and can be used for drilling small holes, cutting ceramics and glass, and finishing complex shapes. Key factors that influence the machining include the abrasive particle size, carrier gas velocity and mixing ratio, work material properties, and standoff distance between the nozzle and workpiece.

5th LF Energy Power Grid Model Meet-up Slides
5th Power Grid Model Meet-up
It is with great pleasure that we extend to you an invitation to the 5th Power Grid Model Meet-up, scheduled for 6th June 2024. This event will adopt a hybrid format, allowing participants to join us either through an online Mircosoft Teams session or in person at TU/e located at Den Dolech 2, Eindhoven, Netherlands. The meet-up will be hosted by Eindhoven University of Technology (TU/e), a research university specializing in engineering science & technology.
Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power gridâs behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
