Installation for controlling tooling including a clamp for performing a determined operation on workpieces, relative displacement of the clamp and said workpieces being controlled by an automatic positioning system

An installation for controlling tooling comprising:

• an automatic positioning system;
• a clamp for performing a particular operation on workpieces, relative displacements between said clamp and workpieces, relative displacements between said clamp and workpieces being controlled by said automatic positioning system;
• drive means for opening and closing and clamp;
• a first unit for controlling the operation;
• a second unit for controlling said automatic positioning system;
• a first servo-control unit suitable for controlling opening and closing of said clamp during the operation via said drive means;
• a second servo-control unit suitable for controlling opening and closing said clamp during a displacement stage via said drive means, said first and second servo-control units being integrated in the first and second units, respectively;
• a sensor for providing information relating to progress of the operation;
• and
• a switch controlled by said sensor, ensuring that during the operation, said drive means being controlled by said first servo-control unit and during the displacement stage, said drive means being controlled by said second servo-control unit.
