The increase in the use of CNC Machining has left a lot of people wondering what it is about and how it came to be. This article highlights some interesting facts about CNC Machining you might not be aware of. These facts include:
CNC stands for computer numeric controlled and refers to any machine (i.e. mill, lathe, sheet metal brake) which uses a computer to electronically control the motion of one or more axes. The name originated in the 1950’s when the need was recognized for machines to be able to manufacture complex jet aircraft parts.
There are two basic ways to program CNC machines: a. Conversational programming. This is the simpler of the two methods. This is a macro programming language used to instruct the machine to perform pre-programmed cycles (i.e. facing, drilling holes in arrays, etc.). With this program, you just specify the essential parameters and the software does the rest for you. b. CAM programming. This is the more powerful of the two methods. Using this method, you import your part model into a CAM (computer aided manufacturing) program and define the parameters associated with each and every machined feature on the part. These parameters include tool diameter and length, depth of cut, tool path geometry among others.
The people trained in the area of precision machining rank among the top five most needed employees in the United States.
It can be used in various industries. The CNC has a wide array of uses and can be used in different industries ranging from jewelry, aerospace, automobiles among other.
Hopefully next time someone gets in a conversation about CNC machining around you, you an dazzle them with these interesting facts.
