  • Laser micromachining and the VIONiC™ encoder

    laser micromachining The VIONiC series of optical encoders is Renishaw's ultra-high accuracy, all-in-one digital incremental encoder for both linear and rotary applications. It has been specifically designed for micromachining processes and other types of precision manufacturing. This article highlights the importance of correct encoder selection with respect to laser machining.

  • New innovative encoder scale opens up new possibilities

    RKLC close-up Renishaw has launched a new substrate mastered encoder scale that adopts the thermal behaviour of the underlying substrate. The RKLC encoder scale is a robust, 6 mm wide stainless steel tape with a thickness of just 0.15 mm. The scale is compatible with Renishaw’s VIONiC™, TONiC™ and QUANTiC™ incremental encoder families.

  • Substrate mastered scale on a CMM

    CMM retrofit Renishaw's encoder scales are effectively either thermally independant of the substrate (floating) or thermally dependant on the substrate (mastered). This article presents an example case where mastered scale might be preferred.

  • White paper: Mounting encoder scales for optimum thermal performance

    linear incremental optical encoder range This white paper discusses how the thermal expansion of position encoder scales can be managed . It includes options on how to calculate and compensate for thermally induced strains. It also explains how an expansion mismatch between the scale and the substrate can impact on the overall performance of the encoder system.

  • Renishaw encoders support the latest in DUKIN’s CMM design

    DUKIN’s Technical Manager, Mr Tae Young Ku The co-ordinate measuring machine (CMM) has become an indispensable tool in the process control regimes of modern production lines. Whether in-line or off-line, CMMs provide the most accurate measurements of parts ranging from turbine blades to engine piston rings. This case study explores how DUKIN designs CMMs that minimise measurement errors through robust mechanical design and position feedback.
