For Rigibore’s automated Zenith solution, accurate in-process measurement is paramount to manufacturing a precision finished bore. Renishaw’s probing technology plays a key role in facilitating the closed-loop tool compensation cycle, allowing it to run without stopping the machining process and without manual intervention.
By integrating Rigibore’s ActiveEdge fine-boring tools with in-process measurement, the Zenith system enables the machine control to automatically compensate for tool wear, reducing machine-tool downtime by eliminating operator intervention. Customers from across sectors such as automotive, aerospace, wind power, marine and toolmaking are now benefitting from accurate and repeatable bore sizes. While Rigibore ActiveEdge tools are responsible for the final cut, this would not be possible without the role that Renishaw probing plays in the solution’s success.
“Accuracy of the finished bore is completely reliant on the measurement provided,” confirms Rigibore chairman Roger Bassett. “The measured value of the previous cut is sent directly to the machine control, where Rigibore macros monitor the measurement against predetermined tolerance limits and, if necessary, a cutting-edge compensation is applied.”
In some high-precision applications, the difference between a good and bad part is a matter of microns and, in some cases, if a bore is out of tolerance after machining, the part cannot be reworked and must therefore be scrapped. These fine margins emphasise the importance of Renishaw’s probing system’s performance and repeatability in delivering measured values, providing the right information for the ActiveEdge tool’s cutting edge to be compensated.
Through the introduction of an automated solution, users will unlock a more productive machining process, eliminating lengthy machine downtime caused by manual inspection, tool setting and adjustment. A recent project in the automotive industry saw productivity increase by 30%.
