Accurate Robot Machining

Industrial robots are highly repeatable but not very accurate. However, through a robot calibration process the accuracy of a robot arm can be improved to the point where it is close to its repeatability, usually under the 0.100 mm mark. This is becoming very attractive to small and medium enterprises as robot arms are very affordable and can be used for multiple manufacturing applications, including machining materials such as wood, plastic or marble.

  • RoboDK
    RoboDK is a simulator for industrial robots. RoboDK simulator makes it easy to program any robot from any brand and generate brand-specific robot programs, being a powerful and versatile Off-Line Programming (OLP) tool. OLP (or Off-Line Programming) means programming robots outside the production environment. OLP eliminates production downtime caused by shopfloor programming. Off-Line Programming is the best way to maximize return on investment for robot systems and it requires appropriate simulation tools. The time for the adoption of new programs can be cut from weeks to a single day, enabling the automation of short-run production. You can easily use robots for Off-Line Programming in industrial applications such as robot milling, robot welding, painting 3D printing and calibrating robots. RoboDK can generate and simulate complex robot paths for more than 200 robots and 15 different robot manufacturers.

  • Autonomous Robots
    Autonomous robots are intelligent machines capable of performing tasks in the world independently of either direct human control or fixed programming. Examples range from autonomous drones, to industrial production robots, to your robotic vacuum cleaner. They combine expertise from the fields of Artificial Intelligence, robotics, and information science.The autonomous robot must have the ability to perceive its environment, analyze situational data in order to make decisions based on what it perceives, and then modify its actions based on these decisions. For example, the scope of autonomy could include starting, stopping, maneuvering around obstacles, communicating to obstacles, and using appendages to manipulate obstacles. There are few autonomous robots in operation today. Even most sophisticated, dynamic robots such as those used in an automotive factory perform according to static programming. And most autonomous robots are only semi-autonomous and will likely remain so even as more fundamental autonomy becomes technically feasible. For example, the Roomba vacuum cleaner does not move according to a pre-programmed route and can modify its route dynamically as its environment changes. However, it has a very limited degree of freedom that is determined by its programming.

  • SOLUTION
  • The work accomplished by Neoset Designs Inc demonstrates the capabilities and results that can be obtained using RoboDK’s offline programming and robot calibration combined. Neoset Designs manufactures unique peaces of art for well renowned artists and designers such as Barry X Ball and Elie Tahari. The accuracy of a KUKA KR210 robot and a KUKA KR 120 R2500 was improved to better than 0.200 mm. The calibration was accomplised by taking less than 100 measurements using the Creaform’s Portable CMM. Compared to other adaptive compensation methods, robot calibration does not require a permanent measurement system installed on the cell and can reach an accurate position immediately without any measurement iterations. Furthermore, robot calibration can be provided as a product as well as a service in partnership with Creaform.
