Reference CMM Delivers High Accuracy With High Speed Data Gathering

NORTH KINGSTOWN, RI - August 24, 2004 - The REFERENCE coordinate measuring machine available from Brown & Sharpe is a high accuracy, high performance, scanning machine that offers advanced dimensional data gathering and analysis capabilities.

The REFERENCE CMM uses advanced Leitz Scanning Probe (LSP) technology for high speed scanning of geometric shapes and free form surfaces. LSP technology combines and optimizes all facets of the probing process including automatic probe weight compensation, advanced motion controller firmware and advanced filtering algorithms to support high-speed, high-accuracy open and closed loop scanning applications. This advanced LSP technology facilitates both high speed scanning of known and unknown contours and the advantage of measuring with very long probe extensions.

The control system incorporates continuous axes motion interpolation, integrating axes movements by eliminating stops and corners. Adaptive scanning modes improve scanning accuracy and throughput by optimizing 3D vector path control for parts with a changing rate of curvature. The result is a smooth, continuous probe path that increases machine throughput by an additional 30 percent.

The REFERENCE CMM features an all-aluminum ultra-rigid frame with a heavy, stable granite table to resist vibrations. Tricision(tm) bridge design orients the bridge for optimum stiffness-to-mass ratio. Dovetail guideway construction with wrap-around air bearings improves accuracy and repeatability. An automatic linear thermal compensation system consisting of sensors installed in each axis scale allows the REFERENCE to adapt to ambient thermal conditions.

The REFERENCE CMM is suitable for all high accuracy applications such as turbine blades, gears, screw and scroll compressors. Long probe extensions and sophisticated engine valve analysis software make this CMM an optimum measuring solution for automotive power train applications.

The REFERENCE CMM can be equipped with QUINDOS(r) or PC-DMIS(r) measurement and inspection software. Options include an automatic probe changer, rotary table and interface to accommodate manual and automatic part loading systems.
