2007-Dec-1 - Tips on CAM Software

The difference with CAM Software levels is the number of Axis the software allows for. Your G Code will tell the software what to do. You will see the standard types below.  Think of it like this, as you add more Axis’, the more sophisticated the software must get and the more it will cost.  It will also give you more flexibility though.  That is the trade off, money for flexibility. Its not about your CNC shop or your Carvewright, but more so the level of sofistication you want. If you are interrested in DIY CNC then you will have lots of decisions to make on the level of software you choose to invest in.

The different types of CAM and CAD Software

There are many different types of CAM Software.  You will need to purchase the type that fits your machine.  For example, if you have a CNC Plasma Cutter, you probably only need a 2D CAM Software version.  The torch will only move in the X and Y planes.  That is if you have a torch height control.
What if you have a CNC Milling Machine with X and Y axes that are powered by stepper motors?  You will probably only need 2.5D CAM Software. Your GCode will not be what holds you back, rather the sofistication of your software.  That is because your parts will have depth.

What if you have a CNC Wood Router and it carves out three-dimensional shapes out of wood?  It has three servo motors to control on the X, Y and Z-axis.  Yep, you need 3D CAM Software.
