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 | Chapter 2 | New Approaches in Engineering Research Vol. 16

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.

Design of Experiments Screening Design Used to Optimize the Punching Process of Cable Ducts Made of Polymer Blend PC/ABS: A Recent Study | Chapter 1 | New Approaches in Engineering Research Vol. 16

When punching cable ducts made of polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS), burr and film are prevalent. As a result, more deburring processes are necessary, which affects the product price. In the following study, the punching process is explored using Design of Experiments to highlight the relationship between the input variables (factors) and the output variables (quality characteristics). Using a Failure Mode and Effects Analysis, the punching process was investigated, and the major causes were identified and rated (FMEA). The rated factors were then chosen using the Pareto method. To set factor levels and a D-optimal screening test plan, the Software Modde was employed. The resulting quality characteristics were systematically assessed using illustrated evaluation catalogues. The mathematical models for quality-characteristics were then optimised and evaluated. Clearance is the most critical component in all five quality criteria assessed, according to the data. It's worth noting that a drop in clearance might be favourable for some quality traits, while a reduction would be negative for others. It is thought that an optimal clearance size exists between these two boundaries. In addition to the clearance, good results require that the material be held down in close proximity to the punch-out during the punching of PC/ABS.
