CAD/CAM-Schnittstelle für die Wickeltechnik - Systematische Entwicklung und Validierung zur beschleunigten Inbetriebnahme

Due to the increased demand for electric traction drives based on electric mobility, the requirements for production technology are increasing. The multi-axis needle winding technology plays an important role for electric traction drive production. It enables fully automated winding of non-segmented lamination stacks and is therefore very well suited for industrial series production. The manual development of a NC-program for such a machine is very complex and time
consuming, which displays a critical barrier especially for prototype manufacturing. Therefore, a CAD/CAM interface was developed at the wbk Institute for Production Science, which enables the automatic development of a winding program from the CAD data of stator, machine and winding tool as well as the winding scheme. ... mehrThe interface is based on a Matlab program that reads in the CAD data in STL format and determines the necessary dimensions using a suitable algorithm. These can be used to calculate support points on which the winding program is based. This article describes the structure of
the interface and how to validate it.
