GCAM - GNU Computer Aided Manufacturing

GCAM is the GNU Computer Aided Manufacturing open source package. It currently supports any 3-Axis Computer Numerically Controlled (CNC) mill, both english and metric units. GCAM consists of a simple interface for making bolt holes, drill holes, sketches, templates, and more. After extruding these entities one can export the corresponding g-code for the selected cutting tool(s). GCAM also imports RS274X (Gerber) and Excellon drill files for gerber to g-code pcb milling conversion used in circuit board prototyping. Once a design is complete one can export the corresponding G-Code to the appropriate CNC driver of choice such as TurboCNC for DOS or EMC for Linux.

CNC Code Maker

A very simple 2D CAD/CAM software with toolpath generation and user-editable postprocessors. Suitable for most CNC machines on the market.

There are post-processor specific cycles, contour cycles and simple point-to-point functions. Fanuc, Heidenhain is supplied with the software.

Drawings can be saved in DXF or a native XML, human readable format.
Import of DXF files (R12) are supported.
Cnc Code Maker is 32-bit application and runs on Windows 2000, XP, Vista, 7.


Simple2D CAD/CAM

This is the Simple2D CAD/CAM project.

A Simple 2D CAD/CAM application (currently Windows-only) for your Sherline CNC mill (or similar).

    Generate decorative gears
    Text from any vector font (OpenType, most Windows fonts, etc)
    Simple pocketing operations (circles, rectangles)
    Geometry mode builds more advanced shapes from line and arc segments
    Arc segments are drawn endpoints-first for easy freehand use
    Tool path generation inside/outside geometry by tool radius
    Unlimited layers
    Unlimited tool definitions
    Define components and reuse them in your design
    Can show the Sherline mill table and tooling plate as references
    The display uses the actual NC code, so you get what's on the screen

This project is BSD licensed.


Enhanced Machine Controller - EMC

The EMC2 team now has a brand new custom Live-CD  based on Ubuntu 8.04 with emc 2.2.x included, that will let you try out EMC2 before installing, and it's also the easiest way to install Ubuntu and EMC2 together.

About the software

EMC (the Enhanced Machine Control) is a software system for computer control of machine tools such as milling machines and lathes.

EMC is free software with open source code. Current versions of EMC are entirely licensed under the GNU General Public License and Lesser GNU General Public License (GPL and LGPL)

EMC provides:

    a graphical user interface (actually several interfaces to choose from)
    an interpreter for "G-code " (the RS-274 machine tool programming language)
    a realtime motion planning system with look-ahead
    operation of low-level machine electronics such as sensors and motor drives
    an easy to use "breadboard" layer for quickly creating a unique configuration for your machine
    a software PLC programmable with ladder diagrams
    easy installation with .deb packages or a Live-CD

It does not provide drawing (CAD - Computer Aided Design) or G-code generation from the drawing (CAM - Computer Automated Manufacturing) functions.

    It can simultaneously move up to 9 axes and supports a variety of interfaces.
    The control can operate true servos (analog or PWM) with the feedback loop closed by the EMC software at the computer, or open loop with "step-servos" or stepper motors.
    Motion control features include: cutter radius and length compensation, path deviation limited to a specified tolerance, lathe threading, synchronized axis motion, adaptive feedrate, operator feed override, and constant velocity control.
    Support for non-Cartesian motion systems is provided via custom kinematics modules. Available architectures include hexapods (Stewart platforms and similar concepts) and systems with rotary joints to provide motion such as PUMA or SCARA robots.
    EMC runs on Linux using real time extensions. Support currently exists for version 2.4 and 2.6 Linux kernels with real time extensions applied by RT-Linux or RTAI patches.

We will provide you with a full sharp license for free as long as you keep coming back to our site once in a while, fair enough? When you register as a user of CncSimulator we will mail you a link to a "petrol file". It will let you use CncSimulator completely free of charge during 3 months. After this period the only thing we ask you to do is to return to our site and download a new petrol file, for another 3 months and so on.
