Description:
A CNC machine is a
computer-controlled carving machine. It reads G Code that instructs the
machine how to move, what feed rate and spindle speed to use, which
cutting tool should be in the spindle, etc. The machine can be a milling
machine, lathe, router, welder, grinder, laser or waterjet cutter,
sheet metal stamping machine, robot, or many other types of machines.
For
larger industrial machines, the computer is generally an on-board
dedicated controller. But for more hobbyist types of machines, or with
some retrofits, the computer can be an external PC.
The CNC
controller works together with a series of motors and drives components
to move and control the machine axes, executing the programmed motions.
In
most cases, a CNC machine is programmed by a programmer using CAM
software who uses the software to apply tool paths to a 3D or 2D model
of the part they want to make.
Once the programmer has finished
his/her programming work, the program is fed into a post processor which
will turn the CAM program into the G code the machine can read.
The G
code is uploaded into a CNC machine along with all the cutting tools
needed, raw material and work holding needed to hold the raw material.
Then a machinist will put the machine into the automatic mode and start the program to make the part.
Grbl
is a free, open-source, high-performance software for controlling the
motion of machines that move, that make things, or that make things
move, and will run on a straight Arduino. If the maker movement was an
industry, Grbl would be the industry standard.
Grbl is for three-axis
machines. No rotation axes (yet) – just X, Y, and Z. There are many
smaller modelmaker-hobbyist style desktop CNC machines. In general,
these are lighter weight, less rigid, less precise, slower, and less
expensive than their industrial counterparts, but can do well for
machining objects out of softer materials such as plastics, foam, and
wax.
It should be noticed that CAM does not actually run the CNC machine, but just creates code for it to follow.
