A Sensor based turning dataset for data-driven surface roughness estimation
Description
Machining data for a particularly difficult-to-machine material, namely Inconel-625 is presented. Inconel is widely used in aerospace applications and is difficult to machine as unlike other materials, Inconel does not get softer with increasing temperature. This data set comprises of 27 sets of Accelerometer data and Dynamometer data acquired during the machining of Inconel -625 on a Kirloskar Turnmaster 40 Lathe. A Mitutoyo Surface Roughness Tester was used to measure the surface roughness after each turning operation.

Steps to reproduce
For the purpose of data collection, a Centre Lathe by Kirloskar® (Turnmaster 40) was used for turning the workpiece. Accelerometer and dynamometer were mounted on it for data acquisition. The workpiece used was Inconel-625 having dimensions 32mm diameter and 130mm length. The tool insert used was PVD coated carbide tool insert CNMG120408-SR-YG401. The accelerometer employed was a Kistler® Integrated Electronics Piezo-Electric (IEPE) triaxial accelerometer. A Kistler® multicomponent dynamometer was employed for acquiring force and momentum data. The signals from the accelerometer and the dynamometer were acquired using a data acquisition system using Kistler DAQ (KIDAQ) along with Kistler Data Acquisition Software connected to a PC. For each set of speed, feed and depth of cut combination, the turning operation was repeated. The data acquired by sensors was recorded and the corresponding surface roughness parameters for each case was measured and recorded separately using a Mitutoyo® SURFTEST SJ-410 surface roughness tester.
