Many companies use 5-axis technology, and companies like Renishaw are moving away from traditional CMM measuring methods. Instead, they are using synchronized CMM motion as well as head axes. That reduces dynamic errors from the CMM probe head axes, which is particularly important when moving at high measurement speeds.

About 5-Axis Measurement
Companies such as Renishaw offer updated 5-axis measurement technology. They are offering more flexibility and speed with tools that have advanced control and sensor technology. While more traditional methods sometimes compromise accuracy, 5-axis technology can be accurate and fast at the same time.
It reduces lead times, boosts the measurement throughput, and allows manufacturers to appreciate the quality of their products better. Some systems have probes and indexing heads, and with the 5-axis motion, you can help your stylus follow a more continuous path, resulting in a better measurement.
That way, it goes around complicated components, and it does not need to leave the material’s surface to index the head or change your stylus cluster. With the controller algorithms, you can synchronize your CMM and CNC touch probe and the head motion. That creates the optimal tip path, reducing CMM dynamic errors.
About the Technology
With traditional methods of measurement, your CMM does the necessary movements to get your surface data. During acceleration, the machine structure suffers from inertial deflections. That can cause errors in the final measurement.
Today’s system manufacturers have spent many years creating technologies to reduce dynamic errors in CMM touch probe. Still, some systems impose speed limits on the servo system or machine. Beyond that, they can’t take a measurement reliably.
The Advantages of Technology
There are limits to certain types of CMM touch probe technology, but the 5-axis measurement technology goes beyond the limits. There is an articulating head, and as it measures, it moves in two rotary axes. That way, the CMM can consistently move while measuring.
The head is more dynamic and lighter than your CMM. The bandwidth is also better, meaning it can follow the geometry’s changes quickly. At the same time, it does not introduce dynamic errors that can potentially be harmful. That means the surface speeds are faster, resulting in speedier measurement cycles.
Choose the Best CNC Touch Probe
Choosing the right manufacturer ensures you get quality parts. Our company offers probes from the HEIDENHAIN and RENISHAW brand. Each one provides a high degree of accuracy for your application because a CNC touch probe can quickly measure an object’s geometry. It looks for the object’s discrete points using a probe to do so.
