This work describes a test bench developed to measure the cutting torque of scissors as a function of the blades position. The prototype of the machine has been validated by evaluating repeatability and reproducibility of torque measurement while cutting fabric. The dependence of the measured torque from parameters such as the scissors' wear, cutting velocity, fabric pre-tensioning and fabric mechanical properties were investigated. The scissors' wear has been investigated by analysing results of more than 20'000 consecutive cutting cycles. The study sets the bases for the creation of the equivalent of ISO 8442-5 (2004) for scissors.

Abstract
This work describes a test bench developed to measure the cutting torque of scissors as a function of the blades position. The prototype of the machine has been validated by evaluating repeatability and reproducibility of torque measurement while cutting fabric. The dependence of the measured torque from parameters such as the scissors' wear, cutting velocity, fabric pre-tensioning and fabric mechanical properties were investigated. The scissors' wear has been investigated by analysing results of more than 20'000 consecutive cutting cycles. The study sets the bases for the creation of the equivalent of ISO 8442-5 (2004) for scissors.File in questo prodotto:
