The composite materials are largely used (aeronautical), because of their advantageous mechanical properties (weight ratio/resistance). Because of the complexity of the phenomena presenting the zone of cut, current knowledge on their machining is limited and prevents their optimal use. From their constitution, these materials pose many problems during their machining. The objective of this study is to seek the parameters of cut during the composite machining of materials Concrete High efficiency (HPC) and Concrete Fiber High efficiency (HPCF). The latter are proposed for the manufacturing of the molds to carryout composite material parts, but the materials used for the manufacturing of the molds of the composite material parts like polyester, silicone and resin epoxy etc., do not resist to high temperatures, and also to analyze the behavior of the composite concrete during machining. Allowing to avoid the appearance of the defects (heating and wear of the cutting tool). An experimental design of machining of some tests was defined for the research of the parameters of cut (cutting speed Vc, depth of cut ap and advances by turn f). The variation of the parameters of cut for each test showed that machining after treatment, caused problems at particular level as in cutting tools and the appearance of the quoted defects.
