Hydraulic motion control could enable massive energy savings in supercritical CO2-driven rock pulverization
by Rick Meyerhoefer
"Roughly 3% of the world’s generated electricity is consumed in the mining process of breaking down rocks. In Canada alone, mines consume over 150 petajoules annually. For perspective, 1 petajoule can power the city of Calgary for three weeks, so any significant drop in mining energy requirements could have vastly beneficial consequences, both in cost and environmental impact. Natural Resources Canada figured the problem was worth exploring and announced the Impact Canada Crush It! Challenge, urging applicants to develop “a new clean technology solution that transforms how energy is used for crushing and grinding rocks in the mining industry.” Cliff Edwards of Envisioning Labs has what he thinks is a winning idea; using high-pressure and temperature control to pulverize rock with supercritical CO2."

Hydraulic Presses: Matching Energy to Work
Turns out, press control is a fairly complicated endeavor.
by Peter Nachtwey
"Hydraulic presses are usually rated by the amount of force they can apply. Force is required to form the work pieces, but so is energy. One important part of press control is controlling the force that is required to form a part, and this means controlling the energy also."

Communicating with Autodesk 3ds Max
Autodesk 3ds Max is frequently used in the entertainment industry to create 3D model animations and models for games and movies. The ability to make motion paths for modeled items is a powerful feature of this software. Delta's Application Engineers have developed a method to transfer motion profiles created in 3ds Max into an RMC motion controller. Since we have created this method, several users have successfully used it to create motion on a physical system after first defining the motion in a computer.
A video of this method and communication examples are located in this Discussion Forum post.

May - Startup and Setup with Delta RMCs
Starting with a bare, blank controller, Delta Application Engineer David McNichol demonstrates wiring power, inputs, and outputs, then connects the controller to RMCTools to configure. Then is is time to make the first moves with the system. David also shows how to use differential pressure inputs to control force, and goes through the setup process for that configuration. No prior knowledge of RMCTools is required for this webinar.

People at Delta
Josh Harmon - Software Engineering
Delta has an active summer intern program, and we have been fortunate to have a number of talented local college students work with us for several months at a time. If we have a need, many times these interns can become full time employees. That is exactly the path that Josh Harmon, Delta's newest Software Engineer, followed to become part of our team.
Josh is a graduate of Washington State University - Vancouver with a B.S. in Computer Science. Josh states that he had an early interest in programming, starting with web projects on his own. He continued developing his coding skills with his FIRST Robotics Competition team, where he was a part of the software team working on their robot using a camera to identify a goal. As an intern here at Delta, Josh developed the RMCMobile Application for viewing Plot and Event Log files. We are happy to have Josh as part of our Software group.

Tech Tip
Longer Plot Trends in RMCTools
Our Software team is constantly improving our freely-distributed RMCTools software, and one of the recent improvements is much longer Plot Trend durations. This is especially useful when trying to capture strange machine or system behavior. This release supports up to 4 GB of plot data, and the user can individually set the captured plot length and the trend plot length. RMCTools indicates how much memory will be used based on the number of data items being captured and the capture and trend duration settings.
By toggling the captured plot to Show Absolute Time in the Plot Detail window, the user can correlate plot events to Event Log entries. This aids troubleshooting tremendously, enabling the user to see what faults, commands, events, etc. the RMC is reporting when the behavior appears in the plot.
