Embodiment Construction
[0028] The specific implementation of the present invention will be described in detail below in conjunction with the drawings and technical solutions.
[0029] In this embodiment, a cemented carbide double straight-edged milling cutter with a rake angle of 5°, a back angle of 10°, and a blunt radius of 15 μm is used to mill a T800 grade carbon fiber composite unidirectional plate with a fiber angle of 150° Preferably, the processing parameters are shown in Table 1:
[0030] Table 1 Milling processing parameters
[0031]
[0032] The first step: Solve the actual range of fiber cutting angle during the up and down milling process respectively
[0033] From the processing parameters in Table 1, we get:
[0034]
[0035] Satisfy: The actual range of fiber cutting angle in up-milling processing is:
[0036]
[0037] The corresponding range of fiber cutting angle in down milling is:
[0038] ψ D =180°-ψ U ∈[30°,66.87°]
[0039] Step 2: Determine the optimal range of fiber cutting angle accord...
