Punching the side recesses is one of the procedures in the manufacturing of cable ducts. This approach has already been used to successfully treat polyvinyl chloride (PVC). On the other hand, punching flame-retardant polycarbonate/acrylonitrile butadiene styrene (PC/ABS) cable ducts is difficult. The production of burrs and films has increased. Both diminish the ultimate product's quality, necessitating an additional deburring operation. This study seeks to visualise and adjust burr and film making using high-speed recordings and a transparent tool. This indicates the first burr as well as the formation of a film. Then, if needed, optimization steps can be established. Analyzing the existing burr and film is false because the returning punch affects them. The present punching techniques for PVC and PC/ABS were examined in order to create optimization procedures. As a result, the process stages in question were given snapshots from the high-speed recordings. This showed when and why film development began, as well as the fact that PVC and PC/ABS shatter in different ways.
