Improved Manufacturing Process: Software Cuts The ‘Chatter’ In High Speed Machining
Posted on September 20th, 2007 by ScienceDaily: Aviation News
An engineer has helped find a way to "cut the chatter" in high-speed machining of aluminum and titanium aircraft parts. Chatter in milling is an instability that arises because the cutting tool vibrates, making oscillating patterns on the work piece. The tool goes over the patterns, making the tool vibrate even more, yielding deeper patterns in the work piece, worsening until eventually the chatter destroys the tool or work piece.
