In order to reduce the depth of subsurface damage during processing of carbon fiber reinforced plastic （CFRP）， a macro continuous dynamic cutting CFRP finite element model was established based on the Hashin failure criterion. The variation law of cutting force and subsurface damage depth with the fiber direction angle was analyzed. The cutting force and subsurface damage were reduced by introducing a textural tool.The effects of grooved textured tool， circular textured tool and triangular textured tool on CFRP cutting simulation were compared. The results showed that consistent fiber orientation with the change in the cutting force and damage depth at a different surface texture tool trend，with the minimum value at 0° and the maximum value at 90°. Compared with the conventional non-textured tool，both the cutting force and the subsurface damage depth are reduced when the textured tool is cutting CFRP， and the reduction degree of the circular textured tool is the largest.The simulation models are experimentally proven to be accurate and efficient.
