Wear of dies, measured and calculated by the process control system in a drawing machine

$15.00

This paper discusses an industrial trial in a drawing machine. The final dimensions have been measured and calculated from wire weight and length, yielding calculations of dimensions within ±0.01 mm. The dimension measurements in different drafts were compared to the dimensions given by the process control system. It was found that accuracy was not satisfactory, and the wear of the dies was correlated to the wire length.
