Beginner's Guide to the World of CNC Machining

Computer numerical controlled (CNC) machining has transformed the industrial and manufacturing sector in so many great ways. First of all, it reduces or eliminates the need for operator intervention associated with the production of workpieces, thanks to the automated operation made possible by program controls. Second, CNC machine tools facilitate the production of consistent and highly accurate workpieces, as the risk of human error is reduced or eliminated. Third, CNC technology leads to increased production speed, as there is no worker fatigue to slow down production operations. Plus, setup times for CNC machining are much shorter than for traditional machine tools.

But CNC machining is a rather sophisticated production process. For that reason, the first objective of any CNC novice should be to gain a basic understanding of the CNC machining process. The more the greenhorn CNC operator learns about the use of CNC machine tools, the easier it will be for them to familiarise with the tools. This will, in turn, aid in the realisation of the aforementioned benefits and any other benefits that CNC machine tools can provide. Here is a basic run-through of what every potential CNC machine tool user needs to know before adding to the growing of CNC machinists.

Machine construction

If you intend to work with CNC machine tools, you should first familiarise yourself with your machine's construction. Being aware of how your machine is built will help measure the limits of what is achievable with the machine. There are so many operational and capacity parameters you should check, but some tend to be more basic than others. Some of the machine operation parameters you can check include the machine's rapid rate, maximum revolutions per minute (RPM), and fastest cutting federate, as well as accessories to the machine. Details on the machine's construction and capacity is usually found in the machine user's manual. As you read the machine tool builder's manual, make sure you know the various components of your machine and how each works, as well as what the machine can and can't do.

Programmable functions

Another important thing a CNC machine user needs to know about is what functions of their machine are programmable and which are not. Some of the most expensive CNC equipment available on the market are generally almost completely programmable and will only require operator intervention to load and remove workpieces. As for the low-cost models, on the other hand, several machine commands may need to be manually activated. With some CNC lathe machines, for example, axis motion may be the only programmable function. Other functions, such as the spindle speed and direction, may have to be started manually by the operator.

About Me

Mike's Manufacturing Blog

Welcome to my blog! My name is Mike and I live in a small town in New South Wales, Australia. Last year, I retired from my job at the local bank. At first, I thought I would enjoy having the freedom to do what I liked with my time, but I quickly became bored. I started to visit my son who runs an industrial manufacturing plant. I would spend my time hanging out with him in his office and walking around the factory. I learnt an awful lot while I was there and it really got me interested in the manufacturing process so I decided to start a blog.
