GHEORGHE VASILE, CATALIN FETECAU, DUMITRU AMARANDEI, ALEXANDRU SERBAN EXPERIMENTAL RESEARCH ON THE MILLING PROCESS OF SOME COMPOSITE MATERIALS Milling is a very common process in the manufacture of plastic parts. In a technological process, milling may be the final procedure, consequently influencing the quality of the product. To determine the optimum processing conditions, it is necessary to make an accurate model of the forces in order to describe the process in terms of cutting parameters. Experimental research has been conducted on the influence of the cutting parameters on the milling cutting force components. This paper aims to obtain the equations that define the variation of the cutting force components by the milling process parameters in the processing of specimens of polyamides (PA66, PA66-GF30 and MoS2. These polyamides belong to the class of technical plastics and are thermoplastics with excellent mechanical properties, also used in the engineering industry.
