Recently, a Korean company succeeded in manufacturing ∅1500mm, t90 PP double wall pipe with ring stiffness ‘SN26’ for the first time in Korea. For commercialization, the developed productt must be cut to the required length with cutting machine in the continuous manufacturing process. The cutting operation was attempted with the cutting device(∅18″, 120P Wheelcutter for Aluminum, 2100rpm) used for the conventional PE or PVC pipe(∅1200mm, t70). In order to commercialize the developed product, product must be cut to the required length with cutting machine in the continuous manufacturing process. but the cutting operation was failed. The results of observation after processing, The material of the large diameter PP pipe was fused on the surface of the wheel cutter and the wheel cutter was detached. The purpose of this study is to research the effect of wheel cutter structure and rotational speed on cutting work when cutting large diameter PP pipes.
