cutlet - Panel Cut Optimization
not production ready
cutlet is my naiive approach on guillotine panel cut optimization, primarily concerned with cutting panels from stock sheets of wood.
There are many commercial solutions available, and quite some Open Source implementations.
This project is implemented in Java 1.8, using Maven. Gui is in JavaFX/FXML.
If you want to contribute - please do so, any help would be appreciated.
If you want to use this project - please do so, I would be happy to hear how it is working for you, and what features are missing.
There are 3 projects:
- Lib
- Gui
- Benchmark
The library implements the data structures and algorithms. Gui will become... well... the GUI. Benchmark runs examples and compares them.
A goal was to implement a solid data structure to provide a good framework for research / surveys.
- Platform agnostic
- easy "getting started" and deployment
- Java 1.8, Maven, JavaFX
- built around reusable core library
- build solid data structure
- optimization algorithm agnostic / easy to add new algorithms
- open source
- enable meaningful evaluation of optimization algorithms
- translatable gui
This project is in it's very early stages, so don't expect too much.
- Basic Data structure
- Basic algorithms
- calculate statistics for a generated layout
- Rotation & grain
- material database
- stock database
- saw kerf / blade thickness
- visalize layout
- run optimization in worker thread
- i18n prepared
- save & load (via java serialization)
- layout in FXML / SceneBuilder
- panning
- zooming
- parts editor / table
- stock keeping
- settings/configuration
- basically works
It is executed as a unit test in "mvn test", also in travis.

This project uses Maven to manage library dependencies, build & run.
This means: install maven and execute:
mvn test
The code does not compile on openjdk, the dependency lombok does not work. So the ubuntu users out there should install the oracle jdk.
