Description

FreeCAD is a completely free CAD/CAM system.FreeeCAD is a program in which, apart from creating our own 3D models, we can also prepare machining programs for basic milling operations for CNC milling machines.The basic and most frequently used functionality of FreeCAD is the functionality related to 3D modeling, that is, 3D CAD functionality. FreeCAD has developed enormously in the last few years and is gaining new users every day.However, a very interesting feature of FreeCAD is the CAM functionality.This is functionality that allows you to prepare machining programs (G-Code) for CNC machines.CAM systems are often expensive or, if they are made available free of charge, they have various limitations (for example, they cannot be used commercially, or there are limitations in generating operations, or other more or less annoying issues).FreeCAD does not have extensive CAM functionality, you will not find many machining strategies here, but "standard", often used are available and can be used without restrictions.FreeCAD allows you to prepare machining operations such as:Face Milling,Contour machining,Pocket machining,Holes milling orDrilling.As you can see, these are simple and basic operations, but in many cases, these operations allow us to prepare comprehensive machining.Putting this together, except that FreeCAD is completely free (even for commercial use), does not need internet access to work, we can use it on any number of computers, no one will suddenly introduce changes and restrictions (we do all updates manually, that is we decide ourselves whether we update to the new version or not).FreeCAD is becoming quite an interesting solution.The big advantage of FreeCAD is that in FreeCAD, we can design a 3D model and prepare a machining program based on this model. So we do everything in one program.We can also prepare a machining program based on a 3D model created in another 3D CAD system (based on a STEP file).What will I learn in this course?In this course, you will learn how to prepare machining operations in FreeCAD based on a 3D model, such as:Face Milling,Contour Machining,Pocket Machining,Holes Milling,Drilling.You will learn how to simulate machining and how to generate a machining program (G-Code) for a CNC milling machine.FreeCAD allows you to generate machining programs for GRBL (Candle), Mach3 and LinuxCNC. These are controllers often used in amateur, hobby and semi-professional CNC milling machines.
