| Symptom on screen | What's actually happening | The fix (not guesswork) | |------------------|--------------------------|--------------------------| | | Too much stretch, too fast | 1. Increase drawbead height? No! Reduce bead force. 2. Increase blankholder force gradually. | | Crack on sidewall | Material is sticking | 1. Add lubrication (increase friction to 0.15). 2. Increase die radius (R>5x thickness). | | Wrinkle in flange | No tension | 1. Increase drawbead lock. 2. Move blankholder closer. | | Wrinkle in panel center | Too much loose metal | 1. Increase blankholder force. 2. Add a step bead. | | Springback (ends up) | Elastic recovery won | 1. Overform (negative springback compensation). 2. Add restrike station. |
In AutoForm, the Punch moves . In reality, the press ram moves. Same result, different mental model. autoform manual
Here is a step-by-step guide to using Autoform: | Symptom on screen | What's actually happening
Before dissecting the manual, one must understand the machine. Autoform is a dominant name in the realm of sheet metal forming and die design simulation. However, in a physical context, "Autoform" often refers to highly specialized sheet metal processing machinery—such as decoilers, straighteners, and feeders—that prepares raw material for stamping presses.
