Method & Evidence

AimTo develop and evaluate a novel algorithmic control system for wire bending machines to improve product accuracy and precision.

MethodComparative experimental study

ProcedureTwo sets of equilateral triangle wire forms were produced: one using a standard bending machine and another using the same machine equipped with a proposed hierarchical control algorithm. Ten different dimensions were tested, with ten trials for each dimension. The accuracy of the produced forms was compared against CAD/CAM designs.
