The Two Main Types of CNC Are for Lathes and Milling Machines

The two main types of CNC, or computer numerical control, machinists that you see in machine shops across the world are for lathes and milling machines. When a machinist first starts, he slowly learns the basics and works his way up to more advanced operations, including the programming and operation of machines with more than the standard amount of axises. CNC Lathe Beginners CNC lathe machinists who are just starting out may be able to change tooling and perform simple setups on the machine. They usually do not have the capabilities to program, but exceed the standards needed for CNC operators. CNC beginners are able to make offset adjustments when parts are out of tolerance and are able to use all the various types of measuring tools including calipers, micrometers and height gauges with ease. They are aware of what the cutting tools are doing and when the part looks correct as far as shape and finish. Advanced and Intermediate CNC Lathe Professionals CNC lathe professionals are more advanced machinists who are able to program a part using a blueprint. They are usually capable of using a CAM, or computer-aided manufacturing program to plot the part and create the tool path. They are familiar with G Code as well and can usually use the conversational language available on the machine control. They can choose all of the tooling necessary to perform a job and are well aware of the speeds and feeds necessary based on the material being used and the type of tooling. CNC MIlling Machine Beginners Beginners on a CNC milling machine are able to perform simple tasks related to the cutting of material in a CNC milling machine. Operators normally are used to place material in the vise or fixture after a part has been completed, but a beginner CNC milling machine machinist is also capable of setting up jobs and picking the correct tools based on recommendations of moire advanced machinists. They are also able to use the many measuring tools available including gauge blocks, micrometers and dial calipers. Advanced and Intermediate CNC Mill Machinists Advanced and intermediate CNC mill machinists are able to program the operations necessary to cut metal and other materials in a CNC milling machine. The programming is often the most difficult part as you must make it efficient, but also make sure that the tools you are using do not wear out prematurely. These machinists are capable of calculating feeds and speeds based on materials that will allow the shop to get the most cutting performance out of a tool. Advanced mill machinists will know how to program using the four and fifth axis and how to utilize more modern tolling such as index cutters and macro-programming. Source: ehow.com
