Description

Roundness measurement dataset

This dataset contains measurement data of roundness reference workpieces. The measurements were performed to test a new developed variable diameter three-point roundness measurement device ROMES by comparing ROMES results to measurement results obtained with a roundness measurement instrument.

Measurement with Talyrond roundness measurement instrument

Raw measurement data of five roundness reference workpieces measured with Taylor Hobson Talyrond TR31c roundess measurement instrument.

  • Gaussian filter with 15 UPR cutoff according to ISO 12181-2 was applied before calculating the roundness profiles and roundness values.
  • Converted values in .csv format are the displacement values in micrometers 3600 points per revolution.
  • Software to convert measurement data from Talyrond .PLN file format is included in folder pydpack/

Three-probe measurement

Workpieces 1 and 2 were measured with a new three-probe roundness measurement instrument mounted in a lathe.

  • For each measurement, 10 rounds of data with 2500 pulses per revolution were measured.
  • CSV files contain values for index number, S1, S2, S3 and S4 (not used)
  • All tactile probe readings (S1 to S3) will need to be multiplied by 1/409.6 to obtain the displacement in micrometers.
  • Nominal angles of the tactile probes are 0, 49.75 and 88.75 degrees.
