Applicant: Renishaw PLC, Great BritainPatent number: US 5,813,287Publication date: 29 September 1998Title: Co-ordinate positioning machine
The invention relates to a co-ordinate positioning machine such as a machine tool, inspection robot, or co-ordinate measuring machine. Co-ordinate positioning machines include a table for supporting an object upon which the machine is operating, and an arm movable relative to the table, typically with three linear degrees of freedom, which carries an operating module such as a cutting tool, an inspection probe, or a welding arm. In this case the arm is supported relative to the fixed structure by three powered telescopic struts, each of which is universally pivotally connected to both the arm and the frame. Consequently the arm is able to move with three rotational degrees of freedom. Movement of the arm with each of these degrees of freedom is constrained by a passive device.
