  White paper: Ballbar testing with circle, diamond, square machining tests

  This whitepaper describes how Renishaw ballbar tests can be used in tandem (or in some cases in lieu of) a 'Circle diamond square' cutting test to evaluate machine tool performance.

  White paper: Interferometric angle measurement and the hardware options available from Renishaw

  This paper describes the operational principles behind Renishaw's interferometric angular optics and how they can be used to measure pitch or yaw errors in a linear axis, the angular accuracy of a rotary axis, or surface flatness.

  White paper: Interferometric calibration of rotary axes

  This paper describes the operational principles behind Renishaw's XR20 rotary axis calibration system and how it can be used 'on axis' to calibrate axes of rotation. For details of angular measurement on linear axes, refer to the relevant paper in the XL-80 support area.

  White paper: Laser diagonal measurement for machine tool performance assessment

  The introduction of B5.54 and ISO 230-6 machine tool performance measurement standards has increased the popularity of laser interferometer diagonal, step diagonal and vector methods for the evaluation and compensation of machine tool errors. This is due to the potential reduction in test times these methods can provide compared with the more conventional laser interferometer based linear, angle and straightness measurements, taken along lines parallel to the machine’s X, Y and Z axes. This paper provides an updated overview of laser diagonal measurements for machine tool performance assessment. It is based on the work in a previous Renishaw paper combined with significant updates to reflect the changes since then.

  White paper: The benefits of remote interferometery for linear, angular and straightness measurements

  This white paper examines each measurement mode (linear, angular and straightness) and explains the benefits of taking measurements interferometrically, with remote interferometer optics and the laser mounted on a tripod. It also draws attention to the importance of the environmental compensation system for linear measurement accuracy.
