    Techne (R) CAD/CAM

    2.5D CAD CAM emphasis on CAM and toolpaths

    A Windows only 2.5D CAD CAM application. The user experience tightly integrates the CAM aspects when doing design and layout. The target users will layout their design and then immediately generate CNC code. The goal is a design application closer to Adobe Illustrator than to AutoCAD. The user specifies machining aspects during object creation so that when the design/layout phase is completed the toolpath generation can occur automatically. What is 2.5D? Objects created are flat (2D) but have a depth component. So you can create a square that will be machined at a specific depth but the depth will be constant accross the square. It is not/does not: A general purpose CAD (AutoCAD) type program. Support reference dimension on the drawing. Export or import major CAD file formats.

    OpenWAM
    The 1-dimensional gas-dynamics code. More information in http://www.openwam.com Modeling is an important technique for the optimization of internal combustion engines (ICE). The use of calculation models together with experimental tests is producing unquestionable successes due to the fact that both techniques complement each other. 1D wave action models simplify the engine by means of ducts, where only one dimension is considered, and volumes where mass accumulation is considered and the gas properties are uniform in the entire element. Finally, non dimensional models are used to solve connections between 1D and 0D elements. Thanks to more than 20 years, more than 10 PhD Thesis and many research projects and publications, CMT-Motores Térmicos has developed an own 1D gasdynamic tool called OpenWAMTM which gathers an important know-how on air management, compressible flow, turbocharging, chemical species tracking, numerical analysis and many other aspects of engine modeling.

    Mach3 Threading Helper

    Mach3 Threading Helper

    Helps with the Mach3 CNC Threading functionality

    This Application assists the usage for CNC threading, especially the Mach3 software. The threading cycle uses the G76 command with some parameters. This program lets the user select from hundreds of predefined or free definable thread standards and calculates the parameters for the Mach3 command line. So, essentially just select your thread, calculate it, copy & paste the result to a GCode file, hit "Cycle start" and you get exactly what you want. Also included is a little tool to calculate the pitch diameter of a thread based on a measurement with three wires. Supports the threading standards M, G, R, BSW, BSF, UNC, UNF, UNEF and tapered Pipe R/Rc and Metrical threads. New: NPSM, NPT, NPTF, NPSC, NPSF. Includes an improved version of the Mach3 M1076.m1s threading macro and a matching screenset. Try also the Feed Calculator: www.sourceforge.net/p/feedcalculator

    Automatic Drawing Generation

    Automatic Drawing Generation

    A canvas library for generating technical drawings

    The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a GObject-based library where a custom application can put common CAD entities such as paths, hatches and dimensions, to automatically create technical drawings. A demo application is provided in order to show the capabilities of the canvas. Although it is possible to interact with the library directly in C (that is what the adg-demo program is doing), the canvas is expected to be used from higher level languages, much in the same way as what done in the GNOME stack. Lua bindings based on LGI are already provided out of the box. The adg-lua project, downloadable from the "Files" section, provides Lua programs and demos that leverages these bindings.

    wirecutter plugin for inkscape

    This plugin exports G-Code for a wirecutter

    The "wirecutter" plugin for inkscape is a plugin to generate g-Code for a 2D wirecutter with a turning table. You can either draw one open path which is the path which the machine will cut or you can draw some closed paths. These closed paths (e.g. Letters) must be connected because the cutter cannot leave the raw material like a milling machine. The Plugin helps you to create these connectors. If you have a wirecutter with a turning table you can create multiple "cuts" for different positions of the turning table. This software is not really tested and is still in development.
