A CNC machine, or Computer Numerical Control, refers to a process used in the manufacturing sector that involves the use of computerized technology to precisely control machine tools that form basic materials into useful, everyday objects. Some examples of CNC tools include grinders, routers, mills, and lathes.

While there are certain applications that have been designed so that anyone with even minimal training can operate a CNC machine, these applications tend to be extremely rare in the manufacturing industry. A CNC operator, or practically any other position in materials casting and object manufacturing requires a good knowledge and skill set to be able to operate the machinery safely and successfully. Seeing as this is the case, the more training one has, the better the operations will be.

While this myth is logical and makes sense, this is generally not how things work out. The reality is that any difference between the way a machining or metal casting job, for instance, was run in the past and the way it is currently running could potentially cause a problem. For a job to run consistently without any problems, variations must be eliminated.

Though CNC machining and modern casting methods deliver great consistency, the machines cannot do all of the work alone. It is true that jobs run in the past can more easily be duplicated in the future, but, these jobs still need a thorough examination in order to eliminate nuances and variations in their workpieces and tools. Therefore, it’s a good idea to have a machinist who can properly oversee the job and can identify any anomalies and dulling tools in order to get the job done on time and at the highest level of quality.

Because CNC machines are computer-based, it’s easy to think that every single function and aspect about CNC machining is autonomously controlled by computers. Though computers do play a rather significant role when it comes to CNC machining, it also relies heavily on G-code. G-code, if you’re not already familiar, is a common umbrella name that refers to the most widely used numerical control programming language, and has many variants. Thus, it is vitally important to have a machinist who knows how to make modifications to a CNC machine.

It’s also easy to think that machining and casting with various materials are relatively easy due to the computerized automation of the process. But, what we have to remember here is that it’s important to have the right trained and skilled people on the job so that there are no accidents and that things get done efficiently and correctly. True, machining processes consistently deliver high-quality and efficient products, but loading and unloading workpieces, activating and monitoring cycles, and making adjustments take skill, experience, and extensive training.

If everything goes as expected with a machining or casting job, then yes, typically they should always take about the same amount of time to run. That being said, while CNC machines and other industrial casting tools automate work and make production easier for everyone, they also don’t guarantee the same run time for each and every job.
