| 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.

| AutoeditNC |
|
AutoEditNC is Free! The current release is in perpetual beta and has a number of limitations. However, it is functional and has been tested by many community college and high school students.
AutoEditNC is a 32-bit Windows program to assist in the creation and testing of Numerical Control (NC) programs in the Fanuc/G&M-Code format. AutoEditNC is a specialized text editor with NC code creation tools. AutoEditNC will also simulate the movements of the machine tool so that the student can test his or her program for accuracy and reliablility.
AutoEditNC serves as a learning tool for beginning programmers. It contains code creation windows that give a brief explanation of the code and allows the user to insert the code directly into his or her program. If you are currently using a text editor for writing NC code, you will find that AutoEditNC can increase your productivity.
AutoEditNC was developed primarily to serve technical college and high school manufacturing technology programs. Students and instructors will find that G&M-Code programming is much easier to learn when AutoEditNC is used to write NC code. Students often find that writing code by hand is tedious and prone to syntax errors. AutoEditNC gives the user tools that make it easy to get started and easy to remember the arcane codes used in G&M-Code programs.

| CollabCAD |
|
CollabCAD is a 3D CAD CAM Software system for collaborative design & development of Industrial Designs.It provides a total solution from product design, numerical control, visualization, simulation, analysis to content management, workflow and office automation. CollabCAD is an initiative of National Informatics Centre (NIC, Department of Information Technology).
CollabCAD is developed on the Linux platform and is available on Windows and Linux (Red Hat and Mandrake). CollabCAD bundled with Knoppix is also available. CollabCAD is developed using open source software tools such as Java/Java 3D, Open Cascade geometry kernel and supports open standards of data exchange such as XML, STEP, IGES, and VRML to ensure interoperability.
CollabCAD Modules
- Design & Drafting
- Surface Modeling
- Solid Modeling
- Collaborative Design
- Database Link
- Data Exchange
- Basic NC Operations
- Customization
- Visualisation
- Content Management System
- WorkFlow
- ERP MRP Module
- FEA Module
CollabCAD facilitates the conventional CAD/CAM capabilities like design, drafting, surface and solid modeling, feature based modeling, basic NC features, data exchange, scripting etc. Surface models can be reverse engineered from point cloud digitized data, obtained from raw/scanned data. CollabCAD also provides reflection line analysis for visual inspection using Zebra Stripes mapping. The Zebra stripes mapping is a surface evaluation method for checking surface continuity.
CollabCAD also offers other niche features like Bar Code to link the designs to non CAD utilities like MRP, Meshing, Creation and linking of databases etc. CollabCAD also provides database connectivity and a component library framework. It enables the user to create or use a Component library. CollabCAD has also been integrated with an Advanced multi-purpose CFD Software for Engineering Design and with a Casting Simulation Software
Current version of CollabCAD supports basic NC operations like lathe roughing, lathe contouring, lathe center drilling, lathe thread cutting, point-to-point operations, surface milling, tools and animation.
Besides the conventional CAD/CAM features, it also provides a collaborative framework for CAD/CAM professionals to work across a network and concurrently access the same design for viewing and modification. It also offers an interactive design environment through audio and video conferencing, for on-line communication between participating designers.
Integrating CAD with PLM, CollabCAD provides an interface to a content repository and incorporates security, locking and versioning of the engineering drawings and documents. It further provides an interface to a workflow system and enables the user to specify, execute, monitor and coordinate the organizations flow of work. CollabCAD also provides an interface to an open source enterprise automation software.
CollabCAD provides a Finite Element Analysis Module (currently only for linux based distributions). It provides pre and post processor for Meshing, Modifying and Analysing Geometrical Structures. The user can - Modify, import/export, repair/clean CAD models, - Mesh CAD elements, check quality, import/export mesh(MED,UNV,ASCII) - Handle physical properties and quantities attached to geometrical items. The Finite Element Solver offers a full range of multiphysics analysis and the modelling methods go well beyond thermo-mechanical calculations, applicable for linear as well as non-linear structures. It provides a wide range of functions to set physical properties of prepared models and simplifies calculations. It support Data Exchange Format(MED),Command file Editor and analyzer (EFICAS). It has a well built user Interactive Interface and serves as a solver/analyzer between pre and post processing.

| 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 chose 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.
