Achieving precision assembly

Automotive Design & Production, August, 2006

ACHIEVING PRECISION ASSEMBLY Rather than relying on, say, hydraulic force for assembly, achieving linear pressing force through driving a ballscrew with a servomotor is more accurate and controllable, according to the people at Promess Inc. (www.promessinc.com; Brighton, MI). They've developed two more Electro-Mechanical Assembly Presses, one that provides 200 N of force and the other up to 1 kN. Monitoring and control can be performed via encoders and CNC; additional sensors (e.g., load cells; position probes) can help create an intelligent assembly system.
