TOOL CONTROL
As shown in Figure
Figure
Depending on the draw type, the tool velocity and force are applied according to the following control scheme:
CRASH FORM Upper tool with defined tool velocity
INVERTED DRAW (SINGLE ACTION) Upper tool is controlled by velocity
Binder is controlled by either velocity or force
TOGGLE DRAW (DOUBLE ACTION) Upper tool is controlled by velocity
Binder is controlled by velocity or force
FOUR PIECE DRAW Upper tool is controlled by velocity
Upper binder is controlled by velocity or force
Lower binder is controlled by velocity or force
If the default
unit is selected, the unit of velocity and force are in mm and
Note:
1. In the QS interface, all force controls are implemented after the binder is closed using velocity control. That is, the velocity control is switched to force after binder closing.
2. In the QS interface, the force applied to the lower binder (in FOUR-PIECE DRAW) is controlled by velocity or force with rigid body control. Rigid body control will prevent the lower binder from moving up before the upper and lower binders clamp the blank.
For example (INVERTED DRAW):
If the user needs to control the punch with velocity and the binder with force control:
a. Provide punch travel velocity (default is
b. Provide binder velocity (default is
c. Provide binder force (default is 200,000
