Process foundation Component quality is dependent on machine performance. Without understanding the errors in a machine it is impossible to have confidence that your components will meet specification. Accurate measurement and setup of machines is the foundation of process control, providing the best performance and stable environment for the machining process. Quantifying process capability reduces costs and improves efficiency. XR20 rotary axis calibrator

Highly accurate and repeatable rotary axis calibration Historically, machine tool rotary axes were confined to large machines, or small indexing tables. As the introduction of smaller 5-axis machine tools and mill-turn designs increases, so do the challenges associated with their measurement. As with linear axes, rotary axes are subject to errors relative to the intended positioning. This can be due to machine installation errors, collisions or general wear in use. Errors in either the angular positioning accuracy or alignment of the axes can produce significant defects in finished parts....

System overview The XR20 consists of an integrated angular retroreflector mounted on a precision servo-controlled axis. The angular position of this axis, and the optics relative to the main body housing, is controlled by a very high accuracy encoder system with the scale directly machined onto the main bearing. Key features and benefits Flexible and lightweight designed for single-handed easy fitment to a wide variety of rotary tables, lathes and other rotary axes High accuracy ±1 arc second verification of rotary axes in any orientation Rapid testing quick test setup and fast data capture...

Off axis rotary measurement Some rotary axis calibration systems require that the measuring device is mounted on the centre of the machine’s rotational axis. This can lead to difficulties on machines where access to the centre of rotation is limited, such as trunnion and swivel head machine configurations as shown in Figure A. The Renishaw solution allows the XR20 to be mounted easily and a test program automatically generated using CARTO software. This synchronises linear and rotary moves so that the laser beam alignment is maintained throughout a test as shown in Figure B. Off axis rotary...

CARTO software suite The CARTO software suite is used for capturing data, analysis and compensation for rotary measurement using the XL-80 laser or XM-60 multi-axis calibrator. CARTO is made up of three applications: Capture to collect laser measurement data Explore for powerful analysis to international standards Compensate for quick and easy error correction The CARTO user interface provides a simple process flow that enables users to easily capture and manage their data. Built in functions such as ‘automatic sign detection’ and ‘first target pre-set’ give confidence that collected data...
