Renishaw has added a new process monitoring window to the shop-floor user interface of its Equator gauging system.

The software instantly displays the measurement results of inspected features to the operator on a bar graph display. It also shows the history of measurement on each feature so that process trends can be seen.

The system’s remastering process can now be managed based on temperature limits, the number of parts or time elapsed since the the last master, while a status bar chart shows inspection results for the last part measured, as a proportion of tolerance either side of nominal. If required, the system can be set up to display just key features.

According to the company, one of key strengths of the software is its ability to cope with changes in shop-floor temperature, based on the traditional comparison of production parts to a reference master part, by re-zeroing the system with an inspection routine.

Key benefits and features

  • The configurable system allows extra warning limits to be set so that the operator can take action before a process reaches 100 per cent of the tolerance. At the warning limit, the bar turns orange; if the process drifts further and the pass/fail tolerance is exceeded, the bar turns red and remastering can be enforced with an on-screen message to the operator.
  • The scale can be changed to show the history of a few recent parts, or to show more parts, so that any trend in the process can be seen, which is suitable when a process is likely to drift, for example when the cutting tools used to machine the inspected surfaces are subject to wear.
  • The company claims that remastering is as swift as measuring a production part and immediately compensates for any change in the thermal conditions of a shop-floor environment.
  • Changes in ambient temperature can be detected with the built-in sensor of the software, which warns the operator that remastering is needed.
  • Historical measured data can be exported in two formats; .csv for use in a spreadsheet; or .jpg images for use in reports. These options are available through on-screen buttons and allow .csv or .jpg files to be saved on the Equator Controller or on a network location for other applications to use.
