THIS PAPER DESCRIBES A COMPUTER-INTEGRATED ASSEMBLY SYSTEM USED IN THE DISK DRIVE MANUFACTUIRNG ENVIRONMENT FOR COMPLEX ASSEMBLY AND REWORK OPERATIONS. THE SOFTWARE, HARDWARE AND ARCHITECTURE FOR COMMUNICATION AND EXECUTION OF ROBOTIC ASSEMBLY ARE INTRODUCED. THE ASSEMBLY LINE IS A FLEXIBLE SYSTEM FOR ASSEMBLING THE MAJOR COMPONENTS OF A HIGH-CAPACITY DISK DRIVE. THE MAJOR COMPONENTS IN THIS DISK DRIVE ASSEMBLY SYSTEM ARE PRESENTED ALONG WITH THE AUTOMATION ISSUES ASSOCIATED WITH THE APPLICATION. THE VARIOUS FACTORS ESSENTIAL TO SUCCESSFUL ACQUISITION AND IMPLEMENTATION OF THE ASSEMBLY SYSTEMS ARE ALSO DISCUSSED.
