Workpiece measuring machine

摘要

A measuring machine includes a table, a base and a metrology frame that supports carriages for moving a probe around the working volume of the machine. The metrology frame is fabricated into a lightweight but torsionally rigid structure. The base that supports the metrology frame on the table is rigidly connected to the metrology frame but is kinematically located on the table by supports. The table and the base can also be made as relatively lightweight structures but distortions of the table due to heavy workpieces are not transmitted to the metrology frame. The construction of the machine also enables it to be easily dismantled and packed for transportation.
