Sensor data set, radial forging at AFRC testbed

General information on the data set

Radial forging is widely used in industry to manufacture components for a broad range of sectors including automotive, medical, aerospace, rail and industrial. The Advanced Forming Research Centre (AFRC) at the University of Strathclyde, Glasgow, houses a GFM SKK10/R radial forge that has been used as a testbed for this project. Using two pairs of hammers operating at 1200 strokes/min, and providing a maximum forging force per hammer of 150 tons, the radial forge is capable of processing a range of metals, including steel, titanium and inconel. Both hollow and solid material can be formed with the added benefit of creating internal features on hollow parts using a mandrel. Parts can be formed at a range of temperatures from ambient temperature to 1200 °C.

For the provided data set, a total of 95 parts were forged over two days of operation. Each part was forged with machine parameters outlined in the file Met4FoF STRATH test plan v4.xlsx. Deviations from the test plan occurred during the second batch and are outline in the sheet Batch 2. Each forged part was then measured using a CMM to provide dimensional output relative to a target specification and tolerances. The CMM records 16 dimensional measurements.

The aim of the measurement setup is to predict the quality (in terms of dimensional properties) of the forged part from the sensor measurements during the forging process.

Structure of the data

* The sensor readings for the forging of the parts are provided in csv files in the folders ScopeTraces_DOE1 and ScopeTraces_DOE2 for DOE1 and DOE2 respectively. For DOE1 the scope traces are named Scope0001.csv to Scope0050.csv. For DOE2 there were deviations and the Scope Traces to billet mapping is outlined in Met4FoF STRATH test plan v4.xlsx. Each file contains the readings (columns) against time (rows). The first column displays the clock times (in milliseconds).
* A commentary on the sensors is provided in the file ForgedPartDataStructureSummaryv3.xlsx (NOTE: Some columns do not have sensor descriptions as this information is not available).
* The CMM data is provided in the file CMM_DOE1.xlsx and CMM_DOE2.xlsx for DOE1 and DOE2 respectively.
