Dataset for Digital Twin paper

Description for each folder:

1) The "raw_signal_data" folder contains original sensor data. The origigital sensor data is named as "ACF-x-x.xlsx". In each excel document, three directions of vibration, current and force sensor data is included.  Naming rules is as follows: "ACF-1-2.xlsx" represents the orginal sensor data from first layler's second slot in. "ACF-2-3.xlsx" represents the orginal sensor data from second layler's third slot.

2) The original real measured surface roughness is in the "Ra.xlsx". The corresponding cutting parameters for every raw signal data of each slot are shown in "Ra.xlsx" document as well. 
3) The prediction results from different models are save in "prediction_results". The detalies are listed below.

   "BPNN_all_signal.xlsx" is the prediction result from BPNN used the combination of all sensors data as the model input 
    "BPNN_current_signal.xlsx" is the prediction result from BPNN used only the current sensor data as the model input 
    "BPNN_force_signal.xlsx" is the prediction results from BPNN used only the force sensor data as the model input 
    "BPNN_vibration_signal.xlsx" is the prediction result from BPNN used only the vibration sensor data as the model input
    "ELM.xlsx" is the prediction result from ELM used the combination of all sensors data as the model input 
    "GPR.xlsx" is the prediction result from GPR used the combination of all sensors data as the model input
    "LASSO.xlsx" is the prediction result from LASSO used the combination of all sensors data as the model input
    "MLR.xlsx" is the prediction result from MLR used the combination of all sensors data as the model input
    "SVR.xlsx" is the prediction result from SVR used the combination of all sensors data as the model input
    "cnn_all_signal.xlsx" is the prediction result from CNN used the combination of all sensors data as the model input
