Research on cutting parameters of PCD tool when machining wear resistant layer of high pressure laminated flooring

Cutting parameter is the key factor influencing cutting performance of PCD tool. SYNDITE CTH025 from Element Six Co. were adopted to fabricate cutting tool for machining High Pressure Laminated (HPL) flooring. Based on series of machining experiments on wear resistant layer of HPL flooring with PCD tools, the effects of machining parameters on cutting force were investigated and the changing rule of cutting force with various cutting parameters was obtained. It can be concluded from the experiments that the cutting force will increase with the cutting depth and the feed rate, and decrease with the increasing of the cutting speed. The effects of machining parameter on tool wear, cutting quality and machining efficiency were also analyzed. At last, the selection of machining parameters was summarized for machining HLP flooring with PCD tool. Among all the experimental parameters, it was considered that high machining efficiency and good quality of workpiece can be obtained when n = 6000 r/min and f = 10000 mm/min.
