SPRINT™: MTM Toolkit

For multi‑task machine tools used in the manufacture of highly accurate diameters.

Exceptionally repeatable measurement of diameters on multi‑tasking machines.

Completely new automatic measure-cut processes in the order of a few microns.

Additional measurements of part run-out, machine centre-line and circularity.

SPRINT scanning system for diameter measurement on multi-task machines

The SPRINT MTM Toolkit offers exceptionally repeatable diameter measurement to producers of Y-axis multi-task machine tools for use in the manufacture of highly accurate diameters.

Integration of this toolkit delivers a number of game-changing capability enhancements – most notably a highly repeatable diameter measurement cycle. With the required artefact, this unique cycle (patents applied for) is not affected by thermal changes to the machine structure or the on-centre error of the component. It provides users with the potential for extremely accurate automatic cut-measure-cut operations with tolerances of a few microns.

The Toolkit returns results for diameter, part run-out, machine centre-line and circularity, with measurements typically repeatable to within 1 to 2 µm.

The SPRINT MTM Toolkit comprises a series of software cycles, executed using Productivity+™ CNC plug-in software, and engineering support – provided by Renishaw to the machine tool builder. This allows for the integration of cycles and artefacts into machine designs.

The supplied cycles, which are programmable through the CNC macro, control the OSP60 SPRINT probe during the required diameter measurements on a reference artefact and the workpiece. These automatically compensate workpiece measurements by using the reference artefact measurements, thus minimising thermal effects on the CNC machine tool. The measurement results are stored to macro variables on the CNC machine tool control.

These cycles use the outstanding 3D scanning capability of the SPRINT system to collect measurement data from every part of the component surface, whilst rotating the part and interpolating the machine axes simultaneously, thereby reducing measurement variation from component form and machine positioning.

SPRINT probe

OSP60 SPRINT™ probe

The OSP60 scanning probe has an analogue sensor with 0.1 µm resolution in three dimensions to provide exceptional accuracy, giving the greatest understanding of workpiece form.

Constructed from the highest grade materials, the OSP60 is robust and reliable in the harshest machine tool environments and able to withstand shock, vibration, temperature extremes and liquid ingress.

A range of SPRINT-specific styli is available to complement the enhanced capability provided by the OSP60. Easily identifiable by a black stylus holder engraved with the exact ball diameter, these styli include a number of design elements which offer improved metrology performance for machine tool applications, in comparison with standard styli offerings.

On-machine software

CNC plug-in screen shot

Harness the power of on-machine scanning with Productivity+ CNC plug-in software and open up a new world of process control.

This on-machine software controls the OSP60 scanning probe, the machine tool, and the PC‑based data tools, enabling more advanced data processing than traditional methods. Real time data processing during measuring or cutting minimises cycle time and results in a high-speed, accurate, and capable process.

The Productivity+ CNC plug-in provides exceptional ease-of-use for machine operators and programmers, with its on-line editor allowing the measurement program to be updated on the machine.

The close integration of controller and CNC plug-in is designed for automatic closed-loop process control to reduce operator intervention.

Data link to machine controller

OSI-S SPRINT™ system interface - front view

 The OSI-S interface synchronises the SPRINT system with the machine tool and passes data between the OSP60 and the Productivity+ CNC plug-in software.

Optical transmission – high-speed communication

OMM-S SPRINT™ system receiver

The OSP60 probe and OMM-S receiver unit communicate via a high-speed optical link. The unique communication protocol provides reliable, high-speed and robust data communication.

Two OMM-S receivers can be used in tandem to increase optical range and machining area coverage; particularly useful in large and multi-axis machines.

Game-changing applications

The SPRINT system incorporates ground-breaking technology which allows organisations to completely re-think the use of on-machine process control measurement in high value CNC manufacturing tasks.

Working in conjunction with manufacturing organisations in key industries, Renishaw continues to develop specific application capability to improve manufacturing processes.

Based on this experience, the SPRINT system is offered in conjunction with a variety of software toolkit packages for data processing, each focussed on an individual task or industry sector.

The capabilities of each package vary by application but typically include:

  • Editing and programming tools for process planners and CAM users, provided as an extension to Productivity+
  • On-machine data analysis tools which run automatically in-cycle, and provide measurement feedback to a CNC machining process
  • Documentation to allow programmers and users to understand the cycles and use them to their best effect

In some cases Renishaw may be able to provide programming and support capability for these applications.
