Computer Numerical Control or CNC machines executes control commands programmed before automatically. Stock materials such as blocks of metal or plastic is transformed into parts of a finished product. The digital designs made using Computer Aided Manufacturing and Computer Aided Design are turned into instructions that it interprets to be able to cut the parts.
There are various reasons in wanting to learn the way in operating them. This can be a career choice that you want to pursue or a business venture that have been on your mind for a while now. Whatever that reason may be, watch a CNC machine video training in order to help you out in familiarizing the concepts that will be presented here.
In creating an object using these machines, the basic process starts with designing the object first. You can do this using the CAD software in a personal computer. Using the CAM software, the design will then be translated into directives that would be converted as specific commands and codes for the CNC machine.
The codes programmed will be then tested to ascertain that no problems will happen by an operator. This process called cutting air is an essential step. When there are mistakes with regard to the speed or the tool positions then a possibility of producing a scrapped part or the machine being damaged will happen.
The two categories of CNC machines are conventional technologies and novel techniques. Conventional technologies uses physical tools such as lathes, drills and milling machines. In lathes, the stock materials spins while the drill bit approaches it and cuts it on contact. While in drills, the drill bit is rotating and approaches the material to cut it.
Novel technologies on the other hand uses specialized techniques in cutting. Techniques include electronic beam machining, laser cutting, plasma cutting and water jet cutting machines. These are used in special cases that involves a special type of material. These technologies are more commonly used in mass manufacturing materials made from durable metals while conventional are usually used in making prototypes.
Different materials are possible to be used as well. Some examples of them are plastics, wood, fiberglass, steel, copper and other metals. The materials to be used largely depends on what the object you wish to create and what its uses would be. The many options of various materials you can use gives it an advantage over 3D printing which has limited types of material available as of now.
Objects and the parts for it were manually machined before resulting in large margins of error. Using CNC machines, it can lessen the margin of error to a minimum and the process repeated a number of times with precision. Making of complex shapes is also possible. Companies use these in mass production for their products and the parts of it because of its ability to repeat various processes while the precision is still maintained in all the objects created.
These are basic concepts of the involved processes in the CNC machining. Watching training videos for them will be of great help in seeing the processes yourself. To easily learn these concepts, a background in industrial arts, mechanical drafting and mathematics is very helpful.
