Lo strumento principale dell'ambiente Path è l'oggetto Percorso. Un oggetto Percorso descrive il movimento che la testa della macchina deve eseguire per lavorare un blocco di materiale, nel caso di macchine a controllo numerico, o per aggiungere uno strato di materiale, nel caso di stampanti 3D. Gli oggetti Percorso possono contenere informazioni di movimento, ma anche altre istruzioni per la macchina, come ad esempio la velocità di rotazione che deve avere l'utensile, o la quantità di materiale che deve essere utilizzato.

Introduzione

L'ambiente Path viene utilizzato per produrre delle istruzioni di tipo Codice G da un modello di FreeCAD. Il linguaggio G-Code è usato dalle macchine CNC e da alcune stampanti 3D per produrre oggetti 3D reali.



Lo strumento principale dell'ambiente Path è l'oggetto Percorso. Un oggetto Percorso descrive il movimento che la testa della macchina deve eseguire per lavorare un blocco di materiale, nel caso di macchine a controllo numerico, o per aggiungere uno strato di materiale, nel caso di stampanti 3D. Gli oggetti Percorso possono contenere informazioni di movimento, ma anche altre istruzioni per la macchina, come ad esempio la velocità di rotazione che deve avere l'utensile, o la quantità di materiale che deve essere utilizzato.

Depending on your interest in the Path workbench there are different topics for further reading:

  • If you are a new new user trying to get familiar with Path, you might be interested in a fast walk-through tutorial.
  • If you have a special machine which cannot use one of the available postprocessors you may want to learn about post-processor customization
  • As an experienced user you may want to write a macro or automate a process might need to learn about scripting
  • Power users who want to streamline their workflow can learn about customization.
  • New developers who want to contribute to path might want to understand core concepts.

General concepts

The Path Workbench generates G-Code defining the paths required to mill the Project represented by the 3D model on the target mill—in [the Path Job Operations FreeCAD G-Code dialect ], which is later translated to the appropriate dialect for the target CNC controller by selecting the appropriate Postprocessor.

The G-Code is generated from directives and Operations contained in a Path Job. The Job Workflow lists these in the order they will be executed. The list is populated by adding Path Operations, Path Dressups, Path Partial Commands, and Path Modifications—from the Path Menu, or GUI buttons.

The Path Workbench provides a Tool Manager (Library, Tool-Table), and G-Code Inspection, and Simulation tools. It links the Postprocessor, and allows importing and exporting Job Templates.

The Path Workbench has external dependencies including:

  1. The FreeCAD 3D model units are defined in the Edit-> Preference...->General->Units tab's Units settings. The Postprocessor configuration defines the final G-Code units.
  2. The Macro file path, and Geometric tolerances, are defined in the Edit->Preferences...->Path->Job Preferences tab.
  3. Colors are defined in the Edit->Preferences...->Path->Path colors tab.
  4. Holding tag parameters are defined in the Edit->Preferences...->Path->Dressups tab.
  5. That the Base 3D model quality supports the Path WB requirements—passes Check Geometry.

FreeCAD Path Workbench internal G-Code dialect represents Feed rates in Units/Second—what the G-Code Inspection tool will show. The Postprocessor is configured to generate the appropriate Feed rates—either in Units/Second or Units/Minute for the target mill.

Script

L'ambiente Path offre una vasta gamma di script API in python. Con gli script python è possibile creare e modificare i percorsi, o estendere le funzionalità disponibili nell'ambiente.

The Path Workbench shares many concepts with other CAM software packages but has its own peculiarities. If something seems wrong, this might be a good place to start.
