Renishaw says its Sprint machine tool probing system incorporates on-machine analog scanning technology to enable fast, accurate form and profile data capture for prismatic and complex 3D components. With scanning speeds of 49 ft./min (15 m/min) and the ability to measure 1,000 3D data points per sec., it provides opportunities for on-machine workpiece measurement, inspection, adaptive machining and process control, while optimizing machine usage and cycle times.
At the core of the system is the OSP60 scanning probe, which contains an analog sensor with 0.1-micron resolution in three dimensions to provide a comprehensive understanding of the workpiece form. The sensor technology provides a continuous deflection output that combines with the machine position to derive the true location of the part surface. In addition, the system is designed to facilitate automated process control with no operator intervention.
For blade manufacture, the system is well-suited for blade tip refurbishment and root blending applications. The high-speed measurement of blade sections and high data integrity is said to ensure the indication of true part condition leading to an adaptive machining capability. Automated routines for setup, blade alignment, blade scanning and data collection provide significant accuracy and cycle time improvements, the company says.
For multitasking machining applications, the system offers process control capabilities, including repeatable diameter measurement cycles. By employing master part comparison, the system becomes an active control enabling measure-cut processes to be automated for accurate diameters on large parts. This capability enables diameter size to be automatically controlled within a few microns of tolerance.
Other functions include 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 routine with little or no operator involvement.
