What You Should Know Before Buying a 5-Axis CNC Router: Is RTCP Included?
When it comes to CNC machines, you likely understand that more axes translate to greater capabilities.
A 5-axis CNC router allows for cutting on five different sides of a workpiece, all from a single setup. However, you might not be aware that there are two categories of 5-axis CNC routers: those equipped with RTCP (Real Tool Center Point) and those without, often referred to as “false five-axis” machines. At ExtraCNC, all our 5-axis routers come with the RTCP option included.

What we learn from this article?
In this article, we’ll guide you through essential points to consider before purchasing a 5-axis CNC router, highlighting why RTCP is a critical feature for maximizing your productivity. Let’s dive in!
Understanding RTCP in the CNC Landscape
RTCP stands for Rotated Tool Center Point, an advanced feature found in some 5-axis CNC control systems. However, not all 5-axis machines are equipped with this capability.
The Functionality of RTCP
RTCP ensures that the tooltip’s actual contact point remains consistent with the surface of the workpiece. In machines equipped with RTCP, the tool center point is controlled rather than the tool rest itself. This means all commands sent from the controller are based on the coordinates of the tool center point. Essentially, the control system maintains the tooltip’s position in alignment with the program’s coordinates.
The Advantages of a 5-Axis CNC Router with RTCP
With a 5-axis CNC machine featuring RTCP, programming becomes much simpler. You can utilize CAM software to calculate the coordinates of the workpiece contour, while the controller automatically accounts for tool length and wear. As a result, no matter how the tool length changes, the tooltip will always stay on the workpiece contour. This versatility means that a single program can accommodate tools of varying lengths, significantly enhancing your workflow.
Conversely, machines lacking RTCP complicate the programming process. You’ll need to consider numerous factors, including the axes’ movements and tool lengths, leading to more complex programming and potentially wasted time. If the machine or tool changes, you will have to reprogram everything, reducing your overall efficiency and accuracy.
Benefits of RTCP
Versatility: Programs can be reused with different tool lengths, saving time and effort.
Accuracy: By simplifying programming, RTCP helps reduce machining tolerances, leading to better outcomes.
Productivity: With streamlined programming and less downtime, your overall productivity will increase.
Conclusion
In summary, understanding the importance of RTCP is essential when considering a 5-axis CNC router. This feature not only simplifies the programming process but also enhances accuracy and productivity. If you’re aiming to maximize your CNC capabilities, opting for a machine with RTCP is a wise investment that will pay off in efficiency and quality.
