TODAY � The present means are not in line with present and future CLIC requirements (for large capacity and high precision) 1600 x 900 x 600 mm Ahmed CHERIF EN/MME-MM 03. 05. 2011 5

TREATMENT OF A REQUEST FOR LARGE CAPACITY MEASUREMENT � Measurement not feasible � Measure with other means (less precise) � Measured from two measuring stations with an overlap and merging of the results 1 St measurement Overlap 2 nd measurement � Measure with long probes and stylus to broaden measurement volume Ahmed CHERIF EN/MME-MM 03. 05. 2011 6

MEASUREMENTS DONE ON CLIC DB GIRDERS Courtesy of Dominique PUGNAT EN/MME-MM Both extremities of the girder are outside the measuring volume Support points are outside the machine table. Housing of the machine have been removed for the measurement 21/03/2011 7

LONG PROBES USED MICROCONTROLE & BOOSTEC GIRDERS 360 mm • Sphericity Error (typical) : 0. 005 mm • With the used configuration : 0. 012 mm. • Huge number of probes : 20 probes were necessary Ahmed CHERIF EN/MME-MM 03. 05. 2011 8
