List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...
Because of the high power levels available (combined with reasonable cost for the laser), CO 2 lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. [8] In selective laser sintering, CO 2 lasers are used to fuse particles of plastic powder into parts.

Laser marking on stainless steel A laser engraving machine A laser engraver. A laser engraving machine consists of three main parts: a laser, a controller, and a surface. [2] The laser is a drawing tool: the beam emitted from it allows the controller to trace patterns onto the surface.
FreeCAD's own main file format is FreeCAD Standard file format (.FCStd). [9] It is a standard zip file that holds files in a certain structure. [9] The Document.xml file has all geometric and parametric objects definitions. [9]
So, when a mineral forms – whether from molten rock, or from substances dissolved in water – it will be initially argon-free, even if there is some argon in the liquid. However, if the mineral contains traces of potassium, then decay of the 40 K isotope present will create fresh argon-40 that will remain locked up in the mineral.
Laser guidance is used by military to guide a missile or other projectile or vehicle to a target by means of a laser beam, either beam riding guidance or semi-active laser homing (SALH). [7] With this technique, a laser is kept pointed at the target and the laser radiation bounces off the target and is scattered in all directions (this is known ...
