Table 1 Motion-planning principles corresponding to four defined phase-divided segments
From: Phase-Division-Based Dynamic Optimization of Linkages for Drawing Servo Presses
Phase division | Principles of motion planning |
|---|---|
SegWork | Required slide speed being reached as precondition, slide running time in this segment should be as short as possible and the mechanism friction energy loss should be as low as possible |
SegFeed | The time and space should be sufficient for the feeding device to move in the die area, and the fluctuation of eccentric speed should be minimized |
SegDec and SegBkAcc | The time for realizing work rating being met as precondition, the energy consumption should be minimized, emergency stop (E-stop) and braking time requirement should be met |
