Absolute Accuracy bridges the gap between robots on the factory floor and the virtual robots in your CAD environment. Production downtime is minimized because Absolute Accuracy makes your robots exchangeable. Consistency between robots means you can simply replace one robot with another without sacrificing accuracy. Absolute Accuracy means you install and run a perfectly accurate robot. The same toolkit is used from calibration and verification at the ABB manufacturing center, through installation and maintenance. CalibWare™, Calibration Cube™ and Controller Software algorithms are consistent between ABB and your site, thus preventing incompatibilities. A clear "Calibration Guideline" assists you through installation and maintenance activities to ensure an optimal result. The accuracy of your robot is guaranteed in its entire working envelope. Shorter turnaround times Removing errors and difficulties between real and virtual robots shortens your turnaround time for new programs. You save the time and expense of building robot cells as well as loading and running programs for each and every one of them. Product Concept · Controller Algorithms · CalibWare™ · Calibration Cube · Product Offer · Supported Robot Types Product Concept The difference between a virtual robot and an actual robot can be typically 8 mm (0.31"), resulting from mechanical tolerances and deflection in the robot structure. The introduction of the ABB Absolute Accuracy concept bridges this gap with a complete accuracy concept for the entire robot lifetime, ensuring a maintainable accuracy of better than 1 mm (0.040") in the entire working range. The Product concept comprises three interconnected aspects Controller Algorithms Inherent mechanical tolerances and deflection due to load in the robot structure decrease the robot's absolute accuracy. Practical compensation of such errors is a complex and highly non-linear problem. The ABB solution is to compensate positions internally in the controller, resulting in a defined and measurable robot TCP (Tool Center Point) accuracy. A generic robot model is used for each robot family and robot individuals are described by a set of error parameters, determined at ABB. Accuracy of each robot will be ascertained and verified through the "Birth Certificate" which statistically describes the robot accuracy in a large sample of robot positions. CalibWare™ The CalibWare PC based software tool, together with the Calibration Cube, represents the key tools in the Absolute Accuracy Maintenance Toolkit. It enables the user to install, verify and maintain the accuracy of Absolute Accuracy robots throughout the entire robot lifetime. Resident within the RobotStudio™ environment, CalibWare uses the existing cell layouts developed using the RobotStudio functionality. Features such as automatic position set generation are easily and efficiently performed using the advanced graphical display of the RobotStudio environment combined with the intelligent calibration software of CalibWare. The five major facets of CalibWare are detailed as follows: Automatic Position Set Generation. Simply draw the cell in RobotStudio, add a robot tool and an appropriate measurement system from the CalibWare Library and generate optimized collision free calibration positions. Import of Measurements. Import text file measurements from any 3D measurement system using the proprietary CalibWare import format. Calibration. Determine the robot's error parameters from a set of robot positions. The parameters are saved in an ABB configuration file for loading into the controller. Cell Alignment. Determine coordinate-system relationships between components in the robot cell, including robot base, fixture frames and the World Coordinate System. Automated Measurement Capability. Currently supported for systems containing Web Ware automation and the Leica LTD500, automatically measure any calibration positions shown in the RobotStudio environment. Specials Single Model Approach - Same models in the Industrial robot controller as in CalibWare. Ensures consistency between ABB and the Customer site. Calibration Checklist - Simple step-by-step guides through calibration activities. Accuracy Menu - Control your maintenance activities to your desired accuracy level. Calibration Cube The Calibration Cube represents the future of level-based calibration systems. The cube offers complete process semi-automation and security. Advanced automation software in the controller interfaces with a highly accurate measurement cube, to offer repeatable calibrations of resolver offsets following maintenance activities such as motor exchange. Product Offer The ABB Absolute Accuracy function makes an actual robot an ideal robot with software compensation of errors caused by load, kinematics and dynamics. The ABB Absolute Accuracy offering consists of 3 parts: Robot with Absolute Accuracy Runtime software as an optional part of the Operating System, including error parameters and birth certificate. a) Resolver offset by Calibration Cube b) Standard resolver offset.
