Renishaw will present the Sprint high-speed contact scanning system for CNC machine tools at Mach 2014, which takes place from 7–11 April at the NEC in Birmingham, UK.

According to the company, the Sprint system incorporates a new generation of on-machine scanning technology that will deliver a step-change in the benefits of process control, enabling fast and accurate form and profile data capture from both prismatic and complex 3D components.

It offers capability for blade-tip refurbishment and root-blending applications, while the high-speed measurement of blade sections coupled with high data integrity (even on leading and trailing edges) is said to ensure the indication of true part condition, leading to an adaptive machining capability.

At the core of the Sprint system is the OSP60 scanning probe, which has an analogue sensor with 0.1μm resolution in three dimensions, which is claimed to provide exceptional accuracy and the greatest understanding of workpiece form.

Furthermore, the analogue sensor technology in the probe provides a continuous deflection output that is combined with the machine position to derive the true location of the part surface.

Key features and benefits

  • Sprint enables fast and accurate form and profile data capture from both prismatic and complex 3D components.
  • Automated routines, such as setup, blade alignment, blade scanning and data collection, result in significant accuracy and cycle time improvements over touch-trigger systems.
  • Users are offered new process control capabilities, including repeatable diameter measurement cycles.
  • Measurement functionality, such as part run-out, machine centreline and circularity, serves to enhance the manufacturing capability of multi-tasking machine tools.
  • Sprint 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 package that is dedicated to a specific industrial task, for example the Sprint blade toolkit. The toolkit includes on-machine data analysis tools, which run automatically in cycle and provide measurement feedback to a CNC machining process.
  • The system can enable 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.
  • Sprint is designed to measure 1,000 true 3D data points per second.
  • According to the company, it reduces scrap and rework, while increasing machine capacity by reducing measurement cycle times.
