The Facts Behind Many CNC Machining Misconceptions
A computer numerical controlled (CNC) machine controls tools, such as a lathe or mill, using a computer program to achieve incredible precision. Just about all industries rely on these custom machined parts and have been for decades. Yet, there are still some myths that give people the wrong impression regarding CNC machining.
As much as we try to share the wonderful opportunities of CNC engineering – all of us covered what a CNC operator does and the 12 reasons why a career in CNC machining might be perfect for you – there are still many common CNC engineering misconceptions out presently there. Get the facts right now!
Myth #1: CNC machining is a dying trade
Fact: Far from it! Yes, CNC engineering has been around for decades, yet advancements in machines just keep getting better, faster, and more accurate. As different types of automation get added to COMPUTER NUMERICAL CONTROL devices, the equipment (and the industry ) continues to grow and evolve.
Think of CNC machining because if it’s a smartphone. Why do people wait in lines and pay big bucks to own the latest version of the Apple iPhone? Because the most recent edition makes life better, and it’s exciting to lead the way. If you don’t possess the most current technology, you’ll be missing out on many features. It’s similar to CNC engineering; not being on the cutting edge may mean you’ll possess a hard time competing in the market.
Myth #2: The best CNC machining is done overseas
Truth: Quite the opposite is true. Supply chain challenges, a global pandemic, and administrative policies have got all forced manufacturers to focus much more attention on domestic COMPUTER NUMERICAL CONTROL machine shops that are proving their proficiency. The reshoring movement is usually powerful, and that includes CNC engineering.
Myth #3: COMPUTER NUMERICAL CONTROL machining is a slow process
Reality: Old-school tapes, dials, and USB sticks have been replaced by CNC programming that directly connects engineers sitting at their desks and CNC devices upon the shop floor. Plus, dozens of setups about pallets are ready to become quickly used with a quick switch of the program.
Myth #4: A COMPUTER NUMERICAL CONTROL machine owner is just a “ button pusher”
Truth: While the purpose of CNC precision machining is to make machining parts easier, it’s not simply pushing buttons. The CNC machine itself does a majority of the work, however this valued trade requires skilled, experienced professionals at all levels. For instance, a CNC owner needs to load castings, monitor cycles, measure results, evaluate quality, and recognize when tooling requirements replacing.
Misconception #5: G-code and M-code is old and difficult to learn
Fact: Common and still used heavily in the marketplace, G-code and M-code will be software development languages that control COMPUTER NUMERICAL CONTROL products. They’re how the pc automatically regulates the engineering tools, and they require the correct coded programmed instruction. Like any technology, it comes down to learning the tips and tricks of coding for specific situations. It’s definitely NOT an out-of-date system.
Fantasy #6: CNC machining is definitely expensive
Fact: For customers who need a large volume of the exact same part, the costs of CNC machining can’t end up being beat. In fact, COMPUTER NUMERICAL CONTROL machining is usually becoming more and more affordable. For CNC equipment shops, presently there is definitely a significant, front end investment to purchase and set up a CNC machine. However, the ROI can be clear intended for CNC equipment shops: repeatability, speed, arranged up ease, and reliability.
Myth #7: All CNC shops are the same
Reality: In the manufacturing world, it takes a diverse company to stand away. A store full of lathes is certainly technically a COMPUTER NUMERICAL CONTROL machine store, but their capabilities are obviously limited. What’s valuable can be a correct CNC partner with a variety of features, experience in many industries, proper certifications, the ability to procure castings, and an in-house architectural department.
Fable #8: Higher education is needed to operate a CNC machine
Real truth: In CNC engineering, a desire to function hard far outweighs any education. Basic math skills and a willingness to learn on the job are the requirements, and any tech school classes are a bonus. High-end CNC equipment shops have got in-depth training programs (with full-time teaching coordinators) to obtain new operators up to velocity and contributing quickly.
Myth #9: CNC machine shop happen to be dirty and dangerous
Actuality: Not all CNC machine outlets value worker safety equally. Some are filthy and some are incredibly clean; it all depends on the shop and how very much is generally invested in cleanliness and employee comfort. Safety features will be built into modern COMPUTER NUMERICAL CONTROL machining centers, and some CNC shops include a full-time security coordinator on-staff.
Myth #10: The backbreaking function wears persons down
Simple fact: Many castings that undergo CNC machining are heavy and/or difficult to handle by hand. Lifting gadgets happen to be utilized for these to minimize any potential injury. The shop’s architectural division might even build a particular lift for a certain component. Some lighter lifting is certainly often required, nevertheless people don’t obtain assigned function that could be beyond their abilities.
Myth #11: There are no career paths in a COMPUTER NUMERICAL CONTROL machine store
Truth: Most CNC equipment shops highly worth people with aspirations and advancement goals. A production machinist can job their particular method approximately set-up technician, supervisor, and actually senior leadership. It is common to see management positions filled simply by people who own moved up from operations. Again, it depends upon what the CNC retail store values.
Misconception #12: Experienced employees do not respect new people
Truth: Although some people observe CNC machine shops since traditional, male-dominated function environments, times have got changed the culture of many shops. In general, the larger the shop, the more progressive the operate environment. Especially during recent labor shortages, skilled workers are extremely valued, appreciated, and rewarded more than ever.
Myth #13: The pace is too hectic
Fact: CNC equipment shops currently have different positions that each need different capabilities, which could include the capability to perform in a rapid pace. Plus, some tasks may require to manage unexpected difficulties – tooling issues, for instance – which could add to workers ‘ stress amounts. Smart shops fit do the job responsibilities to the employee, not really the other method around. Those who want to take in more function and eventually move up are given that chance.
Fantasy #14: The spend is certainly poor in CNC engineering
Fact: The majority of CNC machine shops provide living wages from the very beginning. Intended for inexperienced employees, this is unquestionably an opportunity for entry-level work and schooling that will continue to spend off down the road. Like any trade, with more encounter gained comes more responsibility, choice of shifts, and higher dedicate.
