How to automate any CNC machine (Simple guide)

How can you automate any CNC machine?

Long story short: Industrial robots can automatically load and unload parts, activate and deactivate the CNC machine, monitor the machining process, and even handle post-processing tasks like buffing or polishing finished parts. 

For more information, please visit automatic cnc.

Of course, the real point is finding a robot with the right payload capacity, reach, and skill for your CNC machine.

Additionally, the integration of robots with CNC machines opens up possibilities for predictive maintenance and smarter production planning. 

With the data collected from their monitoring activities, robots can predict when a machine might fail or when tools need replacing, allowing for maintenance to be scheduled without throwing a wrench into your production. 

This proactive approach prevents unexpected downtime and extends the life of both the CNC machines and the tools used.

Robots equipped with AI capabilities can also analyze production data to optimize machining paths and processes, further increasing efficiency and reducing material waste. 

Their ability to learn and adapt means that over time, the robotic system becomes even more aligned with your specific production goals, continually getting better and better. 

So, all in all, incorporating robots into CNC operations doesn't just automate tasks &#; it enhances the intelligence and responsiveness of the manufacturing process.

What can be automated on a CNC machine?

So what exactly can you automate on your CNC machine? Quite a bit, actually.

The most common types of CNC automation include:

  • Part loading and unloading: A robot removes raw parts from a pallet or conveyor and loads them into the CNC machine for machining. It then unloads the finished parts. This frees up your operators from repetitive loading/unloading tasks (they&#;ll thank you for it).
  • Machine activation and deactivation: A robot can turn the CNC machine on at the start of a production run and turn it off at the end of the shift. This helps you make sure the machine is only running when it needs to be, saving energy.
  • In-process monitoring: Robots equipped with vision systems or force sensors can monitor the CNC machining process in real time. They can flag issues like tool breakage, part misalignment or machine errors to cut down scrap and downtime.
  • Post-processing: Robots can handle finishing tasks like deburring, grinding, or polishing parts after they come out of the CNC machine. This eliminates the need for a separate finishing station and additional operators.
  • Quality inspection: Vision-equipped robots can inspect the dimensions, surface finish, and other attributes of CNC-machined parts. They reject any parts that don't meet quality standards before they move on to the next stage of production.
  • Tool changing: Robots efficiently swap out tools in the CNC machine, choosing the appropriate drill bit or milling tool for each job. This automation ensures the right tool for the task without manual intervention, optimizing machining time.
  • Material feeding: A robot supplies raw material to the CNC machine for a continuous production flow. Whether it's metal bars, plastic sheets, or wood panels, this keeps your CNC machine fed without pause, enhancing throughput.
  • Waste management: Post-machining, robots can remove and dispose of or recycle waste material, keeping the workspace clean and reducing manual cleanup efforts. This not only maintains a tidy environment but also complies with safety and environmental regulations.

Why automate your CNC?

By automating your CNC machines with collaborative robots, you can significantly increase your productivity.

Here&#;s how:

  • You&#;ll skyrocket productivity: Robots can run 24/7 without breaks, basically allowing you to get the most out of your CNC machines. 
  • Quality standards you won&#;t believe: Robotic inspection systems detect flaws and non-conforming parts early. Plus, they can do it better than any human.
  • You&#;ll cut down costs: Automation reduces labor costs and improves energy efficiency.
  • Bigger safety margins: Automating dangerous tasks like loading heavy parts into a CNC machine helps avoid injuries and keeps your precious (and squishy) human workers safe. 
  • Endless reuse potential: Modular automation systems can be reconfigured to work with different CNC machines and parts.
  • Deadline woes? Fuggedaboutit: With robots tirelessly working, you're looking at meeting those tight deadlines head-on, delivering orders faster than ever before.
  • Customization? Endless: Robotic systems are undefeated at handling custom orders. They can switch tasks in no time, making small-batch production or personalized orders a breeze.
  • Space savers: Think robots, think bulky? Not anymore. Modern robotic systems are designed to fit neatly into existing setups, maximizing your space without sacrificing efficiency.
  • The green factor: By optimizing energy use and reducing waste, automation not only boosts your bottom line but also your green credentials. It's a win-win for your factory and the planet.
  • Skilling up: Automation doesn't just replace tasks; it transforms roles. Your team gets to upskill, moving into more complex, fulfilling roles as robots take on the monotony.
  • Smooth operator: Integration with your existing systems is not necessarily as difficult as you might think, making sure you get a nice, smooth workflow from design to production.

    Robots talk nicely with your software, making the process smooth and headache-free.

So, the TL;DR is: With the right automation solution, you can transform any CNC machine into a flexible, efficient, and high-quality production system.

How to cost-effectively automate a CNC machine

Digitizing production is a current topic for new machine tools. Everything should be smart and the milling machine should ideally reorder the blanks on its own. Large manufacturing companies are certainly already on the way there, but for smaller production companies in particular, these solutions are often too complex or unprofitable. If that applies to you, we would be happy to help you develop and implement an affordable solution yourself. We always have a quick ROI (Return On Investment) in mind.

Where are igus® products best suited?

Our products for automation are particularly suitable for smaller machines up to 6.61lbs. In addition, igus® is not a system integrator. We just try to give you all the tools to automate your machine yourself with as little technical skills required as possible. Our low-cost automation products are all self-lubricating and, therefore, maintenance-free.

What is the first step in automation?

It would be helpful if the machine door opened by itself after processing and closed automatically after clamping. Then, you can see from the open door where you can add more. For this first step, you need a linear axis with drive and a simple control module. You can find the right linear guides, for example, in our drylin® E modular system and dryve® D1 motor controller (pictured right).  Our software is also available free of charge. If the design fits, you can use it to automate your machine door for less than $1,215.86. This saves you time when loading and unloading and reduces the downtimes of your CNC machine. As I said, we cannot connect it to you, but we will be happy to help you with the mechanical design of our components.   

Is there a cheap solution to automate loading and unloading?

When the door opens and closes automatically, automated loading and unloading is the next goal. To do this, you could place an expensive industrial robot in front of the machine or check whether robolink® can work for you. The big advantage lies in the very simple programming interface, which we also make available to you free of charge. From my own experience, I know that you will be able to program robolink's® movements within two hours. The easiest way to put together your robot solution is to go to www.RBTX.com. There you can put together all products from robots to grippers.  

Conclusion

With our products, you can automate your CNC machine for less than $1,215.86. You can download the software in full in advance at any time and try it out free of charge. Visit our webpage to learn more about our low cost automation solutions or contact an igus® expert here with any questions.
