CNC-computer numerical controlled machines are available in different sizes and models. Anything from small milling machine, plasma cutters to 12 axes water jet machine.
CNC machine basics should be called benefits. The benefits of a CNC machine are the same for each machine as it is for every company who owns one. Computer aided technology is a wonderful thing. A CNC machine offers that benefit to its owners. Intervention by the worker is needed less, as the machine does all of the work once the software is programmed to the specifications desired. The machine will continue to run until the process is complete, all completely unmanned. This frees up the worker to perform other tasks if necessary.
CNC machines offer these benefits:
Fewer mistakes caused by human error
Consistent machining each and every time
Precise machining each and every time
Reduced operator fatigue, if any at all
Frees up the operator to perform other tasks
Speeds up production
Reduces waste
Skill level to operate machine is lower (must know how to program the software)
These are just a few of the benefits that CNC machining centers have to offer. They offer many other benefits that are determined by the type of CNC machine that is used.
Switching from the production of one product to another is very simple and can save the business a lot of time. In the past it could have taken a day to several days to set a machine up to make the proper cuts that are needed for the order. Now, with the CNC machines, set up time is drastically reduced. It’s pretty much as simple as loading a different software program.
CNC machines operate not only through a computer software program, they are motion controlled and operate on several different axes depending upon the type of the machine. The CNC lathe machine operates on the X and Y axis unlike the 5 axis machines that are now available on the market. The more axes that the machine operates on, the more delicate and precise the cuts; the more creative you can become in your projects, and the more you can offer fabrication services. The CNC machines can pretty much do it all without human intervention other than through the use of the computer software.
No more hand wheels and joy sticks causing the motion that most machining tools require. Now, the computer, through the software program, instructs the machine on what exactly to do and the machine continues to perform until the specifications or guidelines have been reached, upon which time it discontinues operation for that sheet of material.
The human intervention that is needed with a CNC machine is the programming. Programming for the machines is written in sentence like structures that are in code. The code tells the different axes what to do and completely controls all aspects of the machine.
