Renishaw has extended its range of machine-tool testing and calibration systems with Axiset Check-Up, a solution for checking the alignment and positioning performance of rotary axes.

Users of five-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.

Renishaw’s Axiset Check-Up provides accurate and repeatable test results using automated probing routines to gather performance data from a reference artefact and provide analysis.

All tests utilise existing spindle-mounted Renishaw touch probes with probing routines generated using machine-specific macro software supplied with Axiset Check-Up.

To perform the test a user quickly locates a supplied calibration sphere within the machine tool’s working envelope using a magnetic mount.

Using the supplied custom macro software, a touch probe is 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.

Measurement results from the Axiset Check-Up test are output to a PC where a Microsoft Excel spreadsheet presents 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.

Analysis of a machine’s capabilities is presented in various formats, including a graphical representation of performance that highlights tracking and centring errors, a function that compares two sets of data for the same machine, a pass or fail test against the user’s predefined tolerances and a history screen that allows comparisons of the performance of rotary axes over time.

All spreadsheet analysis can be incorporated in a simple report generated using Microsoft Word.
