Have you optimized the performance of your robotic arm as it performs milling operations? Machining with articulated robot arms is an attractive alternative to machine tools because they offer ease of set-up, repeatability, a large workspace, and versatility.
However, machine tools are as much as 50 times stiffer than robotic arms (details). This lack of stiffness in robots makes it challenging to produce the desired performance. Minimizing chatter is a frequent concern and should not be overlooked to ensure the right results the first time.
In this article, we explore some best practices for reducing chatter with a focus on the spindle and tooling. [Read more…] about How to Reduce Chatter in Robotic Milling Applications
