Definitions

  • the bending angle Ei is advantageously determined from known data of similar bending tasks that have already been solved. This has the advantage that there is no need to measure the bending angle. This reduces the processing time for the pipe. The measurement errors and uncertainties that may occur during the measurement cannot occur when compared with similar bending tasks that have already been solved.
