CNC Machinists and CNC Operator Information
A CNC Machinist also known as a CNC operator is the individual who is able to run the CNC machine. They are involved with the understanding of the process of their type of machining and are capable of looking at blueprints of the drawings of parts to be created and setting the machine up in order to produce the part.
A CNC machinist must understand various software programs including CAD and CAM and understand the intricacies of the CNC machine they are in charge of operating. The person who works in a certain industry could really know just about all of the types of machining such as cutting, drilling, and milling.
There are several skills that a CNC machinist must have which include:
§ They must be a problem solver to be able to troubleshoot the machine if something goes wrong.
The CNC Machine has limits and capabilities and its important to have a person that knows how to do this.
§ They must understand the CNC process and how it works overall with the machining type they need to produce.
§ They have to be able to identify and use various codes.
The various projects need the workers to be able to get the right tool, find the right tool and load it correctly on the machine.
§ They should also have mechanical aptitude in working with a variety of machines.
Some CNC Machinist are also capable of programming machines but the job could require a separate person to do the programming. If they are a programmer they would also understand how to organize and plan, would be able to read blueprints and have strong math skills.
Another type of CNC Machinist actually does both operating and programming. This individual may have a background in Tool and Dye making or Mold Making or they may be a General Machinist. In this case they would have an extensive background in programming with CNC and machining and planning; the other requirement is that they would have entered into an apprenticeship to learn these skills that would have lasted three to four years, which means that some of their training would have been on the job.
As CNC Machinist continue working with CNC machines they must continually keep up their skills by taking new training so that they can edit CNC programs where necessary. Usually the shop they are working in will upgrade the software occasionally or upgrade the machinery and they will need to be able to process information to these upgrades.
Most CNC machinists have some education but it is usually in the way of a certificate or an apprenticeship program. Since this is a trade, they are able to get experience on the job in some situations. This could be through an apprenticeship or through an entry level position at a company.
Because a CNC machinist is able to do so many things they are generally compensated well. The average salary for a CNC machinist who generalizes is $14.37 to $23.08 an hour. An inexperienced CNC machinist will earn less than one who has lots of experience.

CNC Machining General Information
CNC Machining refers to any process that uses a CNC machine. This could be for routing, milling, drilling, or other types of work that is done with metal, wood or other materials. This is a manufacturing process that uses the automatic opportunity from the computer to create shapes or forms that must be precise.
Raw materials are used and they are put into a CNC machine that uses cutting tools to make these shapes. The CNC machining process involves computers that have at least one microprocessor and several units for storage. With CAD or CAM software systems added to CNC the computer can be programmed to produce the precise movements that are able to create the part.
In CNC machining the process is automated which saves the operator time and saves the business money. The operator is able to load the materials, program the machine and then the machine can work without attention when set up properly; the amount of time it is run without attention is also programmed in.
An important aspect of any CNC Machining is for the operator to know the machine well. CNC is an addition to the general aspects of the machine. As an example, if you are doing routing, adding CNC to the process only automates it. However, for the operator, it means that they must understand the machine, how to put in codes or use CAD or CAM and how to operate the machine; they must also understand how basic routing works.
Another area that is important in order to understand CNC Machining is the basic components of the machine. You are going to always want someone working with the machine who knows how to put it all together so if something breaks they know how to fix the machine. This also allows the operator to understand the limitations and the capabilities of the machine to get the most out of its use.
There are five areas that will eventually come up when an operator is working on a CNC Maching Project. They will first think about the project they want to design and plan it out. This is where sitting down and drawing out plans will be a good idea.
The next area is to understand CAD to translate the drawing into the computer and then an understanding of CAM to translate the CAD information into machine language. In the final area the individual must understand the Controlling function in order to make the machine do what is required. When all these areas are fulfilled properly they allow the individual to create the project in the way they saw it in their drawing.
CNC machining was traditionally only done in commercial settings with very large CNC machines. Today, there are mini-CNC machines that allow the process to be done on a smaller scale in a home workshop. What is nice is that now even a smaller business can take advantage of building parts and projects on a much smaller scale and where not available to them before unless it was a larger scale.
CNC machining can produce both simple and complex designs and can be used on a variety of materials including aluminum, foam, wood and other metals.
