Machine tool precision check

In just a few minutes, users of 5-axis machining centres and multi-tasking mill-turn machines can now identify and report on poor machine alignments and geometry that can cause extended process setting times, as well as non-conforming parts. AxiSet Check-Up provides accurate and repeatable test results, using automated probing routines to gather performance data from a reference artefact, and includes simple, yet powerful analysis. All tests utilise existing spindle-mounted Renishaw touch probes, which are standard fitment on most multi-axis machines, with probing routines generated using machine-specific macro software supplied with AxiSet Check-Up. Set-up is fast and simple. To perform the test a user quickly locates a supplied calibration sphere within the machine tool's working envelope, using a magnetic mount. Via the supplied custom macro software, a touch probe is then programmed to automatically take reference measurements around the sphere. Users are in full control and can define their own test angles to ensure that machines are tested at critical orientations. To ensure the highest test accuracy, the use of Renishaw's high accuracy Rengage strain-gauge probes is recommended, however. Measurement results from the AxiSet Check-Up test are output to a PC where a supplied Microsoft Excel spreadsheet presents easily understood analysis of the data and compares machine performance with defined tolerances. If necessary, a user can then alert a machine supplier to carry out further detailed checks and possible error correction.
