Investigating the Adjustment of Punching Process of Poly Vinyl Chloride (PVC) and Polycarbonate/ Acrylonitrile Butadiene Styrene (PC/ABS) Cable Ducts using High-speed Video Recordings

Abstract

One of the process steps in the production of cable ducts is punching the side recesses. Polyvinyl chloride (PVC) has already been successfully processed using this method. Punching flame-retardant polycarbonate/acrylonitrile butadiene styrene (PC/ABS) cable ducts, on the other hand, is challenging. There is an increase in burr and film formation. Both reduce the quality of the end product and thus make an additional deburring process necessary. Using high-speed recordings and a transparent tool, this research attempts to visualize and adjust burr and film creation. This identifies the first burr and film formation. Then, if necessary, optimization steps can be defined. Because the returning punch effects the burr and film, analyzing the existing burr and film is false. In order to formulate optimization procedures, the existing punching processes for PVC and PC/ABS were compared. As a result, snapshots from the high-speed recordings were assigned to the process steps in question. This revealed the commencement of film development and its reasons, as well as the fact that PVC and PC/ABS shatter in various ways.
