New Life for An Old Saw
"The effect of machine-component obsolescence can be significant, even if the component itself still functions correctly. Consider, for example, a case where a manufacturer/supplier lacks support documentation, or perhaps its staff at the factory is not available to help. In these cases, it can take a long time to resolve a problem, one that may not have been difficult to deal with when the component was new."

Knapheide Saves Costs, Time by Moving Vehicle Life Testing In-House
“The Knapheide Manufacturing Co. has always sent its products out to be tested, but with the wide variety of product types that the Quincy, Ill.-based company makes, the cost of farming out the testing process had become excessive. The manufacturer specializes in the North American utility truck body market, both military and civilian grade, including crane trucks, electrician trucks, and Class 8 heavy-duty truck chassis."

Precise Pressure and Flow Control Improve Wax Injection
“In aluminum investment casting, a disposable wax pattern must be made for each part to be formed from molten aluminum. To make those wax patterns, low-temperature paste wax is injected into cavity molds. To get a high-quality pattern, the cavity must be completely filled so that no air is trapped in the mold, which leaves a bubble or void in the final pattern. Therefore, the flow of paste wax must be controlled so entrapped air can escape through vents in the mold."

Multi-Axis Motion Control Streamlines Sawmill Operation
“Today’s sawmills are hotbeds of motion control. Modern integrated saw lines rely on coordinating the motion of dozens of moving parts to maximize productivity. For example, AMS Solutions, of Enderby, B.C., Canada, designs customized automation solutions for sawmills across North America. Experts at AMS recently completed the design and installation of a new canter profiler gang saw in a dimensional-lumber mill in the Northwestern U.S. The system AMS installed incorporates 26 hydraulic motion axes being managed by a Delta Computer Systems RMC200 motion controller."

Knapheide Saves Costs and Time in Nondestructive Vehicle Testing
“The Knapheide Manufacturing Company of Quincy, IL, is a leader in the North American utility truck body market, so when they adopt manufacturing and testing procedures, the industry takes note. “In the old days we would send our products out to be tested to ensure that they met industry certification standards,” said Richard Pelnarsh, Knapheide test engineer, “but that used to be very expensive, and each test could take weeks to complete, impacting our ability to meet our schedules.” More recently, the company has been developing test systems in house, shortening the process and improving their ability to test customized product configurations. A custom test may also be developed when a need arises to recreate a particular set of events a Knapheide product will experience in the field."

Multi-Axis Motion Controller Synchronizes Press Operation
“Gasbarre Products, Inc. of Dubois, PA makes powder compacting presses in a variety of sizes, capable of exerting compaction forces from 1 to 750 tons. Most of the company’s customers are suppliers to the auto, lawn and garden, hand tool, and recreational vehicle industries. Gasbarre’s presses are used to form complex shapes from metallic and ceramic powder compounds, which are hardened through a high-temperature sintering process after forming."

Tech Tip
We are introducing a new segment in Delta News, where our Applications and Design Engineers can share short tidbits of information about RMCs or RMCTools that may not be well known. We hope that Tech Tip will be helpful, and to possibly expand the feature a bit more in the future.
Diagnosing Gray Code vs. Binary Code Transducer Feedback
by David McNichol, Applications Engineer
Feedback issues can be difficult to deal with. The RMCTools plotting function is always our go-to method of tracking down an issue. When you see this jagged shape to the SSI feedback, similar to the plot below, it isn't noise or a transducer issue, the feedback is just mis-configured!
The settings for the SSI Format are found in the Axis Parameters, and can be changed on either the 'Setup' or' All' tab. By changing the SSI format from Binary to Gray code, or vice versa. . .
. . . we are able to correct the problem, and now we see a clean feedback signal from the SSI transducer, just as we would expect to see.
Delta has a number of ways to learn more about RMCTools and RMC Motion Controllers features. Delta's website has the RMCTools Online Help, which has a searchable index full of technical information. We also host the Delta Discussion Forum, where RMC users can exchange ideas on implementing applications, Applications Engineers will post code examples, and you can find recommendations from Delta's in-house testing of third-party products that work well for high-performance fluid power systems.
