The dataset for paper Roughness prediction of end milling surface for behavior mapping of digital twined machine tools

The original real measured surface roughness is in the "Ra.xlsx". The origigital sensor data is named as "ACF-x-x". In each excel document, three directions of vibration, current and force sensor data is included. 
Naming rules is as follows: In“ACF-1-2", "1-2"represents the second slot in first layler. 
The corresponding cutting parameters for each slot are illustraed in "Ra.xlsx" document.
