LASER TRACKER AIDS JCB JIG AND FIXTURE CALIBRATION
Over the last 70 years, JCB’s reputation for superb build quality has led to worldwide success. In 2008, JCB Heavy Products opened a new £43 million factory in the UK producing 8,000 machines a year. JCB needed to find an effective way of guaranteeing that its high, exact standards are consistently met with every component on every machine. As part of the company’s investment, JCB has developed new machining centres including extremely accurate jigs and fixtures, the use of which puts JCB in direct control of component quality. In order to do this JCB required an external contractor to undertake the jig and fixture calibration procedures. JCB’s pre-delivery procedures are exhaustive including a 200-point check before each machine leaves the factory. Manchester Metrology established a jig and fixture calibration regime using the Vantage Laser Tracker which facilitates the generation of detailed, traceable certificates as highlighted when the jig or fixture drifts from its normal position. This technology allows JCB to pre-empt any possible problems and further ensures continued quality standards whilst simultaneously reducing down time. Andy Young, Manufacturing Engineering Manager at JCB explains, “In addition to calibration procedures, Manchester Metrology’s use of the Laser Tracker has proven invaluable in determining the accuracy of our prototypes. Also, the advanced equipment is used for generating initial sample reports on all new sub-assemblies. We are then able to compare the data to CAD models/engineering drawings and identify areas that could cause future concerns.”

Manchester Metrology Managing Director, Paul Bulman states “We were able to formulate a suitable plan of action to enable accurate, efficient calibration of JCB’s critical jigs and fixtures. We utilised the portable Vantage Laser Tracker as it is ideal for large scale measuring. Having used the tracker and CAM2 Measure 10 software to measure and capture the dimensions of critical features on a jig or fixture, we are then able to compare the data to CAD models and when necessary identify areas that could cause future concerns.”
