For multi-task machining applications, Renishaw says its SPRINT machine tool scanning system offers users completely new process control capabilities, including repeatable diameter measurement cycles. Using master part comparison, this scanning system becomes an “active” control enabling measure-cut processes to be automated for accurate diameters on large parts.
The company says this capability can result in the size of diameters being automatically controlled to within a few microns of tolerance. Additional functionality provided is a rapid health-check of a CNC machine tool’s linear and rotary axes, making it possible to implement a daily machine-monitoring regime with minimal operator involvement.
The system’s OSP60 probe has an analogue sensor with 0.1μm resolution in three dimensions. 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.
