Milling force coefficients-based tool wear monitoring for variable parameter milling [PDF]

open access: yesThe International Journal of Advanced Manufacturing Technology, 2021
Abstract Tool wear is an important factor that affects the aeronautical structural parts' quality and machining accuracy in the milling process. It is essential to monitor the tool wear in titanium alloy machining. The traditional tool wear features such as root mean square (RMS), kurtosis, and wavelet packet energy spectrum are related to not ...
