Global engineering technologies company Renishaw is launching its new SPRINT high-speed analogue contact scanning system for CNC machine tools in autumn 2013.

The SPRINT machine tool scanning system draws on Renishaw's partnerships with major businesses in key industrial sectors to provide a game-changing capability for high value CNC manufacturing processes.

Featuring a new generation of on-machine analogue scanning technology that will deliver a step-change in the benefits of process control, the SPRINT system enables fast and accurate form and profile data capture from both prismatic and complex 3D components. This new scanning technology opens up new process control methods previously not possible with other measurement methods.

Incorporating multiple patented technologies, the SPRINT system enables high-speed, high-accuracy 3D surface data collection through powerful compensation of the static and dynamic volumetric errors, which are often associated with high-speed machine movement.

The SPRINT analogue contact scanning system is a ground-breaking tool with an exceptional range of potential applications, enabling several measurement and process control methods, reducing scrap and rework, while increasing machine capacity by reducing measurement cycle times.

For blade manufacture, the SPRINT high-speed analogue contact scanning system provides superior 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 condition leading to an adaptive machining capability. Automated routines, such as set-up, blade alignment, blade scanning and data collection result in significant accuracy and cycle time improvements over touch-trigger systems.

The SPRINT machine tool scanning system also offers users completely new process control capabilities in multi-task machining applications, including exceptionally repeatable diameter measurement cycles. By employing master part comparison, the SPRINT system becomes an ‘active’ control, enabling measure-cut processes to be automated for accurate diameters on large parts to within a few microns of tolerance. Measurement functionalities such as part run out, machine centreline and circularity also serve to significantly enhance the manufacturing capability of multi-tasking machine tools.

The SPRINT system also 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 dedicated to a specific industrial task. The toolkits include on-machine data analysis tools that run automatically in-cycle and provide measurement feedback to a CNC machining process.

The revolutionary OSP60 scanning probe at the core of the SPRINT system is an analogue sensor with 0.1 µm resolution in three dimensions, providing exceptional accuracy and understanding of workpiece form. The analogue sensor technology in the probe provides a continuous deflection output that is combined with machine position to derive the true location of the part surface.

Measuring 1000 true 3D data points per second, the system's superior analytical capabilities provide various opportunities for workpiece measurement, inspection, adaptive machining and on-machine process control, whilst optimising machine utilisation and cycle time.

The SPRINT analogue scanning system also facilitates automated process control with no requirement for operator intervention.
