Robotic surgical machines require total geometrical tolerance and zero-play fits where even small deviations caused by multiple processes will not be tolerated. In order to do so, medical robotics need the integration of metrology into the machining process itself. This is where the true value of advanced custom 5-axis CNC machining:
Integrated Real-Time Metrology
We install touch-trigger probes right on the machine spindle, thus providing for the possibility of in-process measurement of key features such as bore locations and mating surfaces while the workpiece is still held. The ability to adjust tools dynamically using real-time measurements results in making an ordinary machining center into a closed loop system, which is necessary for high-accuracy 5-axis CNC machining.
Adaptive Machining for Sub-Micron Precision
The obtained measurement data not only is recorded, but it actually helps inform the following stage of machining. Using our system, the tool paths will be calculated with micro-machining adjustments made where deviations from the nominal model are found. In this way, we attain tolerance levels below 0.01 mm, thus addressing the central issue related to cumulative error in surgical robotic 5-axis CNC machining.
Closed-Loop Manufacturing for Repeatability
Through this technology, a measurable digital thread will be developed for each individual part. Each dimension on a component will be measured and correlated with a specific iteration of the machining program, ensuring that traceability is possible. Control processes like this are essential for achieving repeatable perfection in the 5-axis medical device machining, saving time on the assembly stage.
Precision 5-axis CNC machining goes beyond mere geometric cutting; it is the perfect fusion of material removal and live measurement.
