A G-Code simulator is a type of software tool that provides a virtual representation of a CNC machine’s tool path made by following the instructions in a G-Code file. They range from simple simulators that output a single image of the tool path to complex tools that can detect collisions and plot the path in 3D. The question is a bit vague. Remember that you will need to generate a model in a CAD program (if you are working in 3D), then transform the model to G-Code using a CAM program, then use the G-Code to operate your CNC mill or lathe. For generating your 3D model, I recommend FreeCAD as an open source product.
Mach3 CNC
Mach3 is a software package which runs on a PC and turns it into a very powerful and economical Machine Controller.
Mach3 is a full featured CNC controller suitable for controlling the Lathe ,Mill, Plasma Cutter, Router, Engravers etc.
