Optodyne says its MCV-500 is an efficient and complete laser calibration package for 3D volumetric error compensation of CNC machine tools, coordinate measurement machines (CMMs), and large, five-axis, gantry-type machines for the aerospace industry. According to the company, the system offers efficient calibration and compensation of linear, straightness, squareness and angular errors. For example, using the sequential step diagonal technique, the measurement time for 3D volumetric errors over a volume of 80" × 60" × 40" can be reduced to three hours, the company says.
For machines using low-end controllers, the measured 3D errors can be used to compensate the G code to achieve higher part accuracy. For machines using high-end controllers, such as the Fanuc 30i/31i/32i, Siemens 840D, and others, the measured 3D errors can be used to generate the compensation files and upload directly to the controller to achieve higher 3D volumetric positioning accuracy.
