Robotised finishing center

13 08 2014

Well known for its multifunctional machining centers (rotary transfer machines), Precitrame Machines SA is also a historical provider of high performance polishing machines. The company has just presented a concept of robotic linear transfer machining centers with features that open new perspectives in terms of finishing and polishing. Meeting with Mr. Vincenzo Bonavoglia, Sales Director of the company.

Under a relatively small footprint, the Cyberpolish 640 T can offer up to 5 online cells offering two workstations each. It is controlled through the new Cybermotion 5.0 that offers features never seen before as the high performance trajectory following and the simultaneous management of six robots.

Under a relatively small footprint, the Cyberpolish 640 T can offer up to 5 online cells with two workstations each. It is controlled through the new Cybermotion 5.0 that offers features never seen before as the high performance trajectory following and the simultaneous management of six robots.

The basic concept is simple, let’s imagine a working cell including a robot and two workstations allowing six or seven axes machining. Then let’s multiply these cells to create machines with two to five stations. Parts are gripped in holding devices that move from one station to the next. Thus, it is possible to implement a global chain of finishing (e.g. deburring, felting, polishing and brightening) within a single machine, and in one clamping.

Incomparable cycle time and flexibility
The logic of the sequential work on several stations (and therefore always with operations in hidden time) allows the achievement of extremely short cycle times. Compared with a conventional solution, the tests show gains of 5 times or more.

To gain steps of production?
Nowadays the quality produced by machining centers is steadily increasing and, depending on the part to be done, they can be directly loaded into the Cyberpolish T for all operations from grinding to brightening without having to pass through a specific grinding machine before. M. Bonavoglia says: “In some cases, specialised grinding operations before finishing are always necessary, but for all the others, we can directly finish the parts in one machine and in one clamping just after the milling operations”.

Precitrame will be present at the next AMB with a multifunctional machining centre that will perform an automotive part. The new Cyberpolish series T will be shown through the many multimedia tools of the company.

The world’s first lightweight industrial robot at EPHJ/EPMT/SMT

10 06 2014

LBR iiwa – intelligent industrial work assistant – is KUKA’s new lightweight robot. Equipped with industrial duty mechanics and drive systems, it is sensitive, yielding, precise, flexible and can be used to automate delicate, complex assembly tasks that were beyond the capabilities of robots to date.
Kuka LBR iiwa
Design based on the human arm
LBR iiwa has seven axes and was designed to replicate a human arm. It can be operated in position and yield control mode, and thanks to integrated sensors, the robot’s sensitivity is configurable. LBR iiwa was made for delicate joining processes, and the robot can even handle simple tools thanks to built-in high-performance collision detection algorithms and torque sensors integrated into the joints of each axis. Low weight, seven axes and a slim profile make the robot ideal for tight spaces and easy to integrate into manufacturing lines. LBR iiwa is designed to handle payloads up to seven or fourteen kilograms, making KUKA the first and only company to offer a lightweight robot capable of handling payloads over ten kilograms.

To be discovered
LBR iiwa opens a new chapter in the book of human-machine cooperation. Acting as an operator’s “third hand”, it opens the door to completely new applications in which safety barriers are a thing of the past. Visitors to EPHJ/EPMT/SMT will be able to judge for themselves when they examine solutions at KUKA’s booth. Each of the displays demonstrates LBR iiwa’s unique features.

The company will also shows a KR Agilus robot perfectly tailored to the sector of production in microtechnology.

To be discovered on the C100 booth in Geneva from June 17 to 24, 2014.

Opportunity celebrates 10 years on Mars

19 02 2014

Ten years ago, the NASA rovers Opportunity and Spirit landed on Mars. It keeps going and going and going. “It is equipped with maxon brushed DC motors” the company proudly announced recently.

Today, Opportunity is still exploring Mars – an unbelievably long time, considering the robot was only designed to last about 90 days. It has covered a distance of approximately 39 kilometers so far and continues to roam around a vast area. On board, 39 maxon brushed DC motors can be found.

On January 25, 2004, the Mars rover Opportunity landed in the Eagle crater. Since then, it has been investigating the planet for NASA (National Aeronautics and Space Administration), a USA agency responsible for the exploration of space. It has examined a number of craters, dunes, and flats, always searching for traces of water. It did not take long before Opportunity found first indications (sediment structures, minerals) that there used to be water on Mars. The Mars rover is able to take photos, brush the ground and drill into stone and it continues to do so today. “The rover is in exceptionally good condition for its age”, says John Callas, a manager at NASA. However, things haven’t always been easy for the rover in the past ten years. Its wheels have become stuck in the sand requiring a very difficult maneuver to release them once again. Sand storms disabled the solar panels and prevented the batteries from recharging. Opportunity is now starting to show a few small symptoms of aging: the 185 kg robot has a bit of “memory loss” – every now and again, its hard disk shows signs of wear caused by the long period of use.

39 km and 39 maxon drives
With drives manufactured by maxon motor, Opportunity has been able to safely navigate the surface of Mars for ten years. The rover contains a total of 39 brushed DC motors that are all still operating reliably. They are used to drive the robotic arm, the Rock Abrasion Tool (RAT), the cameras, the control mechanism and the wheels of the rover. The motors are standard products with diameters of 20 to 25 millimeters and an efficiency of over 90 percent. Minor modifications were necessary to adapt the DC motors for the harsh environmental conditions: the temperature on the surface of Mars fluctuates between approximately -120 °C and +25 °C.

This speaks about reliability of maxon motors (as well as all other pieces of equipment on the robot) indeed, but also about human genius. We at Eurotec haven’t thought to use Opportunity to spread the microtechnology messages of our customers to the red planet!

www.maxonmotor.ch

The RE 25 and RE 20 DC brushed motors from maxon motor have been working on Mars for an entire decade.

Shuttle tool changer to be discovered at EMO

12 08 2013

Colombo Filippetti, the Italian company from Torino, will unveil a new optimized shuttle tool changer simplifying operations and management at EMO on hall 26, Stand F07.
Eurotec_CTNE_a+b
The main characteristic is that no hydraulic device is used, this allows impressive results. Compared to the usual devices, the system is noiseless, cleaner and  much more reliable. It is composed of an exchanging unit assembled on a shuttle moved by a servomotor which slides, through rollers, on a hardened prismatic guide.

Vertical and horizontal
The exchange cycle (180° rotation) is completed by using a precision reduction gear with servomotor while the cone extraction stroke is operated by an oleo-pneumatic cylinder. In the version (O+V) it can change the tool with spindle both in vertical and in horizontal positions: in this version the tool exchanger is pivoted in a fulcrum and can rotate by 90 degrees operated by an oleo-pneumatic cylinder. The gripper arm has a mechanical control with shutters when the tool is drawn from the spindle.

Tailored to customers’ needs
The CTNE 50 is completed by different kinds of ring or annular magazines with a number of tools variable from 20 to 80 tools according to production needs. It fits to the following types of cones: ISO 45, ISO 50, BT 50, HSK 80, HSK 100, Capto C8 and Capto C10 with tool weight of 25 kg in the standard version and  35 kg in the heavy version (W). Colombo Filippetti will show some of its more significant products at EMO. It will also be possible to see the different applications of the CTNE 50 on some of its customer’s machines on show at EMO.

PowerMILL Robot Interface for machining with robots

2 05 2013

Delcam has launched the PowerMILL Robot Interface for the programming of robots for multi-axis machining operations.
Delcam robot machining
The new PowerMILL Robot Interface makes programming a robot as easy as programming a five-axis machine tool.

This approach makes it as easy to program a robot for machining as it is to program a five-axis machine tool.  With the Robot Interface being a fully-associated application inside PowerMILL, users have access to all the multi-axis machining strategies within PowerMILL and can use all the system’s project management options to manage, store and retrieve data.

3-step to succeed
The core functionality of the PowerMILL Robot Interface consists of three main steps: programming, simulation (including analysis) and creation of the robot programs. Robots can be programmed for tool-to-part applications, making them ideal for machining large parts, such as composite panels that need to be trimmed, or for part-to-tool applications, such as grinding or linishing.

Simulate complete machining
The PowerMILL Robot Interface can then be used to simulate the complete machining operation and to control the robot’s movements through different variables, such as axis limits, axis priorities and workplane constraints.  Various aspects within the configuration of the robot cell, such as axis limits, tool constraints and home position, can be defined, and the simulation of the robot completed within those constraints.

Actually programme the robot
Once the results of the simulation have been reviewed, and modified if necessary, the program can be output in the appropriate robot native language eliminating any need for third-party translation software.  Acceleration, smoothing values and other robot-specific parameters can be defined as part of the output. Full support for external axes, such as rotary tables and linear tracks, can be included, as well as dedicated tools for spindle calibration.

To see how easy it is to use the PowerMILL Robot Interface, please go to www.delcam.tv/cnc-polystyrene.

The digital age of polishing!

26 04 2013

If the capture of movements (motion capture) was developed in the 1980s for the army and then for physiological and medical analyses, it is Hollywood and video games that have developed this technique for recording human movements through sensors to then recreate them in a virtual manner (as in Avatar for example). At EPHJ Crevoisier, the manufacturer of grinding and finishing centres, will present an articulated polishing robot that operates using the same technique.

Crevoisier_Eurotec

Crevoisier uses the film industry developments to the service of polishing. Thanks to its new acquisition and polishing cells, the perfect gestures of polishers can be reproduced to infinity.

Crevoisier will present in world premiere at EPHJ a polymorphic polishing robot which is able to reproduce the sure gestures of the best polishers. How does it work? What are the consequences for the polishing world and for the watchmaking field (first target of this revolution)?

To work with the polishing specialist
“The goal is to give the polishing specialist a complementary tool” says Mr. Migy, technical-sales mgr. He continues: “Today watchmakers have difficulty to find highly skilled workforce and it is more and more common that they have to subcontract abroad”. In order to keep these added value operations in Switzerland, Crevoisier presents a new concept of programmation for polishing robots.

Step by step
In the event of a series of parts to be polished, the specialist works manually as he is used to on a polishing post. A motion capture system saves all useful movements. Each sequence of polishing realised by the specialist being registered, he can proceed to the next step that will allow the robot to replicate movements.

Roboy will be brought to life soon

22 01 2013

The pioneer project of the Artificial Intelligence Laboratory (AI Lab) of the University of Zurich started six months ago, with the target of developing one of the most modern humanoid robots within nine months. Now the robot has received a new face and is able to move his arms. On March 9, 2013, Roboy will be presented to the public at the “Robots on Tour” robotics exhibition held in Zurich on occasion of the 25th anniversary of the lab. More than 50 brushless maxon drives are responsible for the humanoid’s precision movements.
Roboy_Maxon_Eurotec
Since the project start in the summer of 2012, Roboy’s development has progressed very far. The torso of the 1.30 m robot has been completed and assembled. The two arms are finished and can move; furthermore Roboy has now received a new face. This friendly face is projected onto the head of the robot with a miniature projector and gives him a whole range of facial expressions. This makes his humanlike appearance almost perfect. Roboy will additionally be able to recognize faces that he has learned beforehand. Roboy has been designed as a humanoid tendon-controlled robot (in “normal robots”, the motors are in the joints); this will enable him to move almost as elegantly as a human.

More than 50 high-precision motors and an accurate controller
As main project partner, maxon motor supplies various brushless DC drives that provide Roboy with controlled movement. In total, more than 50 maxon motors, combined with gearheads and encoders, have been installed in the robot. Additionally, all electronic components are from maxon motor. To control the motors and execute Roboy’s movements, a master/slave system has been set up using the digital positioning controllers of the maxon EPOS2 series. Programming of the control functions on the slave system was performed in cooperation with maxon engineers. The drive specialist from Sachseln has many years of experience in robotics, e.g. for medical technology, industrial automation or the astronautics industry. Currently maxon products are in use in the two Mars rovers “Curiosity” and “Opportunity”.

“Robots on Tour” cyborg and robot show
On occasion of the 25th anniversary of the AI Lab, robot fans, robots and cyborgs from all over the world are coming to Zurich for the ”Robots on Tour” (robotsontour.com) The topic of robotics will be presented to the public in many demonstrations. A focal topic is the relationship between humans and robots and the questions that arise from it. What potential does robotics hold for mankind? What dependencies could result? There will be lots of opportunity for scientific exchange in the podium discussions with renowned researchers such as Rodney Brooks, former director of MIT CSAIL (Computer Science and Artificial Intelligence Laboratory) and founder of “Rethink Robotics”.

Switzerland’s first tendon-controlled humanoid robot

28 08 2012

A project team with experts from science and industry, including the drive specialist maxon motor, is developing a new humanoid robot: “Roboy”. On March 9, 2013, “Roboy” will be presented to the public at the “Robots on Tour” international robotics fair that will take place in Zurich as part of the 25th anniversary of the Artificial Intelligence Laboratory (AI Lab) of the University of Zurich.

.

Since June 2012, the project team has been busy implementing the latest knowledge in the field of robotics to create a new humanoid robot. “Roboy” will be 1.30 m big, with an anatomy and motion characteristics that mimic that of humans. With “Roboy”, the project team wants to show what topics are being researched in the field of robotics and which technologies are ready for series production. “Roboy” is a further development of the technology used in the famous “ECCE Robot”. Both robots, “ECCE Robot” and “Roboy”, are equipped with tendon-controlled drive technology, which gives the robots the ability to perform humanoid movements and to react to their environment.

Swiss robotics and drive expertise
In addition to the scientists of the AI Lab, international research groups from Germany and Japan are participating in the project. Furthermore it has the support of partner companies that are providing cutting-edge Swiss high-tech expertise. As main project partner, maxon motor is supplying numerous DC and EC motors, as well as sensors that enable “Roboy” to make high-precision movements. The drive specialist from Sachseln has many years of experience in robotics, e.g. for medical technology, industrial automation or the astronautics industry.
 “High precision electric motors are the artificial muscles of a robot. Our drives are small, dynamic and efficient – just what robotics need,” says Eugen Elmiger, CEO of maxon motor. He adds: “For us, creative and ambitious projects such as “Roboy” are always an incentive to challenge ourselves and to try new things”.
