Automated finishing for tool making processes - Robots remove milling traces from forming tools

08.11.2011
The Fraunhofer Institute for Production Technology IPT has developed an automated manufacturing system for the manufacture of forming tools for use in the automotive industry with which to cost-effectively smooth over and brush-polish tools with reproducible quality.

During the EuroMold 2011 tool and die making trade fair, the Fraunhofer IPT will be presenting this robot-based processing plant at the joint Fraunhofer booth C66 in Hall 11.

Transferring manual dexterity to a robot

The Fraunhofer IPT’s automated plant uses a lineal grinding motion to remove the milling traces that arises when manufacturing forming tools and molds. The manufacturing unit on display at the trade fair consists of a conventional industrial robot and a pneumatic smoothing tool in which the processing movements and the forces acting on the workpiece are introduced and controlled via air pressure. The processing path is programmed using the so-called "CAx-Framework" software especially developed by the Fraunhofer IPT.

Without the right tool holder or process parameters for the robot to reproduce the manual dexterity and the experience of a human operator, it was virtually impossible to automate the smoothing and brush polishing processes on freeform mold surfaces. As part of the "Green Carbody Technologies Innovation Alliance" (InnoCaT), the engineers in Aachen therefore performed scientific investigations to find the right processing methods and tools for different materials and geometries. A comparison of the results of an optical component measurement with the original design data then provided the basis for developing the optimum processing strategy for automated finishing operations.

The plan is to continue developing the system in order to fully automate the processing of free form tools both with robots as well as in milling machines.

The "Green Carbody Technologies Innovation Alliance" is an association of over 60 companies and scientific institutes that aims to make automotive manufacturing more energy and resource efficient. As part of this alliance, the Fraunhofer IPT develops new tool and mold manufacturing systems together with its industrial partners in order to reduce the resource consumption and manufacturing costs involved in component production.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
