Mach3

Mach3 addresses a strict crowd of engineers working with a special equipment called CNC (computer numerical control) machines that operate more or less like plotters do.
If you never have heard about a plotter or you just can’t picture one although you have heard of this term, a plotter is actually a high-precision printer that is used in various engineering domains such as CAD (computer-aided design).
CNC machines are widely used in more fields that you can think of and to give you just a few examples, these comprise drills, EDMs (electrical discharge machine), embroidery machines, milling machines, wood routers, plasma / hot-wire / laser / water-jet cutters, surface / cylindrical grinders, 3D printers or knife / glass cutters.
You can now try to acknowledge the importance of such machinery alongside the software used to program it. Mach3 finds itself in this particular category and what it does is turn your schematics that you import in various formats such as BMP, JPEG, DXF or G-code into real-life components of all shapes and sizes.
Being a program especially designed for a bunch of people, Mach3 is all about functionality and little if anything at all towards looks and other non important aspects in this domain of activity. Do not hope for any eye-candy upon starting it as its over-crowded sections simply makes anyone that does not have a clue about what it is supposed to do immediately close it.
To sum it all up, Mach3 is a professional application for professionals working with CNC machinery. The plethora of options, functions and settings can really be overwhelming if you have no idea about this type of software. For the ones that do posses the required knowledge, Mach3 can prove to be quite helpful.
