CNC control tools such as DRO units and digital encoders play a key role in machine tool automation. Walker Machinery, a major distributor of digital readouts, linear encoders, linear scales, rotary encoders, and more in Brampton, Ontario, explores the basics of machine tool automation and its myriad benefits and challenges in this blog.
What Is Machine Tool Automation?
Machine tool automation is an amalgamation of hardware, software, and CNC controls which are used to perform machining tasks with high accuracy and ease. The main idea is that the process should be conducted with little to no human intervention. For instance, when a program is used to perform a cut using CNC controls, it utilizes a CAD or CAM interface to ensure the cut being performed by the machine is fully automated.
There are two categories of machine tool automation, namely open and closed loop. In open loop, the feedback of the task is revealed in the form of numbers in the DRO unit and is monitored and adjusted by a technician. In closed loop, the manual intervention is eliminated altogether using automated feedback tools and mechanisms such as digital encoders. However, what remains constant is the core principle: the machine tool uses hardware and software to make the operation faster and easier.
What Are The Benefits Of Machine Tool Automation?
High Productivity
Machine tool automation with the right CNC tools can lead to overall productivity within the workshop. While more parts can be machined due to the automation, thereby increasing throughput, it also gives technicians and workers more time to perform other tasks instead of monitoring the machining process. Therefore, in terms of productivity, machine tool automation offers excellent return on investment. In fact, some shops can even run around the clock with proper checks and safeguards in place, especially with a closed-loop system.
Improved Safety
Machining processes can be quite hazardous. Processes such as cutting or milling can pose risks for workers as they handle repetitive tasks. However, by integrating CNC control equipment, machine tool automation can improve worker safety, as they remove the need for manual intervention altogether. Even in the case of open-loop systems, the technician’s work is minimal as they calibrate from DRO readings. So, the risk of being exposed to sharp or hazardous tools is eliminated.
Quality Assurance
Manual operations are always prone to some minute errors. In fact, with closer tolerances and demands for precision, this becomes a major problem. Fortunately, with the use of machine tool automation, this problem can be completely avoided. By the use of digital encoders and other CNC control technology, the process is entirely automated, eliminating the need for human skill, which inevitably leads to errors. Thus, machines can now produce products with precise dimensions and superior quality across a large batch size.
Predictive Maintenance
The benefits of automation also extend to maintenance. Instead of a routine maintenance schedule, using sensors such as digital encoders can help monitor the quality of tools and components. Hence, any wear and tear or drop in performance can be observed in real-time. Consequently, the worn-out part can be promptly replaced before it leads to major downtime. In this way, machine tool automation aids predictive maintenance and gives an additional boost to productivity.
What Are The Challenges Of Machine Tool Automation?
While there are numerous benefits of machine tool automation, it comes with its own set of challenges. This section covers these potential issues.
High Initial Investment
The main caveat with automating machine tools is the high initial investment cost. While the quality and productivity make up for it in the long run, it can be a major investment for workshops over manual machines. However, retrofitting digital readouts to old machinery can act as a middle ground and allow workshops to invest more after experiencing the benefits firsthand.
Skill Gap
The integration of advanced automated tools in a facility will require technician retraining. This gap in skill can take some time to fill, which can slow down productivity in the short term. However, with standardization of tools, it becomes much easier to train technicians, as integrating new machines only requires slight adjustments instead of comprehensive learning for them.
Technical Support Issues
The integration of machine tools for automation also means connecting them to the internet and exposing them to modern software. The upkeep of machines and software can seem like a challenge at the outset, until the details are figured out. However, if done properly, it can lead to a truly modern workshop, with advanced machinery, skilled technicians, and robust tech support.
Conclusion
To conclude, CNC controls in machine tool automation have their own pros and cons, but it is a vital step in manufacturing evolution.
