In the machining process, calibration tools are used to monitor, assess, and improve both the dynamic and static performance of position-critical motion systems. To properly calibrate a device, it is measured under test and compared to a measurement value universally agreed upon as a national standard. While historic calibration techniques only measured displacement of a machine tool along its three axes, modern calibration equipment can detect errors in roll, pitch, and yaw, along with squareness errors, and vertical and horizontal straightness errors. Some modern calibration tools include laser and ballbar systems, multi-axis calibrators, rotary axis calibrators, and machine checking gauges.
Long-range measurement functionality in Carto 4.2 operating software enables Renishaw’s XM-60 multiaxis calibrator to capture and analyze data from a linear axis regardless of how long it is. The program also facilitates Heidenhain linear compensation.
Mitutoyo America Corp.’s QM-Height Series measures height, height difference (step), inside/outside widths, inside/outside diameters, circle pitch, and free-form surface max/min heights to ±(2.4+2.1L/600) μm. Simple-to-use control panel enables most measurements to be made with one keystroke.
The multisensor MiSCAN Vision System is a coordinate measuring machine (CMM) with a microscopic-level scanning probe. The compact MiSTAR 555 is a space-saving in-line or near-line CNC CMM designed for high-speed, high-accuracy measurements with assurance from 10° C to 40° C.
