Every profession has its myths and misconceptions. CNC machining is no different in that regard.
What are some of the most common myths? Find out below:
This one has a little truth. CNC machining can certainly be easy. In fact, the whole concept behind CNC is to make machining parts easier, faster, and more consistently accurate.
But at the same time, it’s infinitely complicated. You can always learn more. Programming, setting up your workspace, and making adjustments can almost always be improved – even if you save just a few seconds. The benefits are faster production and improved product quality.
This one again is partially true. While you can’t grab the first random person on the street and turn them into a CNC machinist, CNC machining does require only minimal training to get started in some cases. But there’s many types of production that require much more than just basic skills.
Loading workpieces, activating and monitoring cycles, measuring workpieces, evaluating workpieces, and recognizing and replacing dull tools takes skill. Experienced operators make a huge difference in any CNC machine shop.
CNC machining isn’t totally automated. It’s not like your employees can just push a button and watch the machine do all the work.
CNC does make consistency in product speed and quality much easier. But it’s not perfect, and it does require some thought. Your employees do need to analyze the workpiece setup and process prior to executing the job to make sure the part gets produced in almost exactly the same way.
If everything goes smoothly and you have an experienced CNC machinist, you can predict, with a fair amount of accuracy, when your job will complete.
But, you also need to account for:
Predicting repeating jobs can be done consistently. But with new jobs, this can be next to impossible.
Nearly every CNC machine uses a CAM system. But, every CAM system outputs the G-Code your CNC machinery needs to run. CNC machinists have an easier time modifying G-Code than changing the CAM system.
Code still matters a ton. And the skill and experience of the CNC machinist matters even more.
When you understand those five myths of CNC machining, you’ll realize how valuable it is to have an employee skilled in CNC.
