# FreeCAD SheetMetal Workbench
A simple sheet metal tools workbench for FreeCAD
### Tutorial by Joko Engineering:
[](https://youtu.be/xidvQYkC4so "FreeCAD - The Elegant Sheet Metal Workbench")
#### Developers:
* Folding tools:
> [@shaise](https://github.com/shaise) Shai Seger
> [@jaisekjames](https://github.com/jaisekjames)
> [@ceremcem](https://github.com/ceremcem) Cerem Cem ASLAN
> ([@JMG1](https://github.com/JMG1)) Based and inspired by Javier Martínez's code

# Wiki
[SheetMetal Wiki at FreeCad](https://wiki.freecad.org/SheetMetal_Workbench)
# Terminology
## Sheetmetal Workbench definitions
## Physical material definitions
# Test case
As a simple test case, consider the following example:
* Inputs:
- Thickness: 2mm
- K-factor: 0.38 (ANSI)
- Leg length: 48.12mm
- Inner effective radius: 1.64mm
- Flange length: 51.76mm
* Output:
- End to mold-line distance: 50mm
You can find a simple calculator in [`tools/calc-unfold.py`](tools/calc-unfold.py).
# Material Definition Sheet
### Description
You can use a Spreadsheet object to declare K-factor values inside the project file permanently. This will allow:
* Different K-factor values to be used for each bend in your model
* Sharing the same material definition for multiple objects
### Usage
1. Create a spreadsheet with the name of `material_foo` with the following content (see [this table](https://user-images.githubusercontent.com/6639874/56498031-b017bc00-6508-11e9-8b14-6076513d8488.png)):
| Radius / Thickness | K-factor (ANSI) |
| ---| ---|
| 1 | 0.38 |
| 3 | 0.43 |
| 99 | 0.5 |
Notes:
1. The cell names are case/space sensitive.
2. Possible values for `K-factor` is `K-factor (ANSI)` or `K-factor (DIN)`.
3. `Radius / Thickness` means `Radius over Thickness`. Eg. if inner radius is `1.64mm` and material thickness is `2mm` then `Radius / Thickness == 1.64/2 = 0.82` so `0.38` will be used as the K-factor. See [lookup.py](https://github.com/ceremcem/FreeCAD_SheetMetal/blob/k-factor-from-lookup/lookup.py#L46-L68) for more examples.
2. Use "Unfold Task Panel" to assign the material sheet.
3. Unfold as usual.
### Screencast
# Engineering Mode
### Description
Some sort of parameters effect the fabrication process but are impossible to inspect visually, such as K-factor, which makes them susceptible to go unnoticed until the actual erroneous production took place.
In engineering mode, such "non-visually-inspectable" values are not assigned with default values and explicit user input is required. "Engineering mode" is a safer UX mode for production environments.
### Activating
1. Switch to SheetMetal WB at least once.
2. Edit -> Preferences -> SheetMetal
3. Select `enabled` in `Engineering UX Mode` field.
# Installation
For installation and how to use, please visit:
