    Default Another DXF to G-code Project

    Hi everyone
    I've just started my CNC project for graduation thesis, I'll create a simple CAM software to assist manufacturing on CNC milling machine, it'll be useful when you work with simple cutting contour, it's also free and light. The soft is programmed on VB.net

    DXF to G-code is a module of the software. This module reads the data from dxf (Autocad Drawing eXchange File) and convert them to NC code. Up to now - in the first stage of the project, it can read a closed contour created from Lines and Arc.
    If you like this, you can download to test it and give me some comments, i'm very glad .
    - The module is being improved so there are a lot of bug. I'll try to fix them and add more features such as:
    + Read ellip and spline curve
    + Cut off all the material out side or inside the contour.
    + Add Blank Properties and cutting parameters.
    + Fix unworking function (zoom, pan, preview...)
    + Add cut layers for cutting to a depth...
    ....
    I'll reupload the soft when finished adding new features. Sorry for my bad English
    Thank you all!

    Thank you for your interesting, surely I'll post the "contour" code, I think it's enough for an EDM machine. The code is written with VB.net 2010, hope it work.

    A newer built with:
    - Zig rough milling outside contour
    - Blank setup

    To use this:
    - Step 1: Select dxf file (dxf has lines only, i'm still working with arcs)
    - Step 2: Define blank in Blank Setup tab
    - Step 3: Input tool diameter
    - Step 4: Input stepover (width per cut) (less than tool diameter)
    (other features are not done yet, so skip them)
    - Step 5: Press generate Button

    Demo (generate and verify tool path):
