The Dynamics Of Better Drilling | Modern Machine Shop

Jun 01, 2001· In milling, this may be the only such vibration that significantly affects the process. But drilling is more complex. While the tool is chattering in and out at some high frequency, it may also be swaying back and forth at a much lower frequency—essentially tracing a cone-shaped volume as the swaying tool rotates.
