Renishaw has announced that it will launch its Sprint high-speed analogue contact scanning system for CNC machine tools in autumn 2013. Sprint’s on-machine analogue scanning technology is said to enable fast and accurate form and profile data capture from both prismatic and complex 3D components. It is particularly suitable for use in blade manufacture and multi-task machining applications.

Sprint is claimed to offer unprecedented capability for blade tip refurbishment and root blending applications. The high-speed measurement of blade sections coupled with high data integrity (even on leading and trailing edges) ensures the indication of true part conditioning leading to an adaptive machining capability.

Automated routines such as setup, blade alignment, blade scanning, and data collection result in significant accuracy and cycle-time improvements over touch-trigger systems, Renishaw said.

For multi-task machining applications, the Spring machine tool scanning system is said to offer users new process control capabilities, including exceptionally repeatable diameter measurement cycles.

By employing master part comparison, Sprint becomes an ‘active’ control enabling measure-cut processes to be automated for accurate diameters on large parts. This capability can result in the size of diameters being automatically controlled to within a few microns of tolerance. Measurement functionality such as part run out, machine centreline and circularity serves to enhance the manufacturing capability of multi-tasking machine tools.

Product information

  • Additional functionality offered by the Sprint system provides a rapid health check of a CNC machine tool’s linear and rotary axes in seconds, making it possible to implement a daily machine monitoring regime with little or no operator involvement
  • Each Sprint application is enabled and supported by a software toolkit dedicated to a specific industrial task — for example, the Sprint blade toolkit. The toolkits include on-machine data analysis tools that run automatically in-cycle and provide measurement feedback to a CNC machining process
  • The OSP60 scanning probe at the core of Sprint has an analogue sensor offering 0.1μm resolution in three dimensions. The analogue technology provides a continuous deflection output that is combined with machine position to derive the true location of the part surface
  • Measuring 1,000 true 3D data points per second, the system’s analytical capabilities are claimed to provide unparalleled opportunities for workpiece measurement, inspection, adaptive machining and on-machine process control while optimising machine utilisation and cycle time
