Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0028] Taking the reaming process of T300 carbon fiber composite material and TC6 titanium alloy laminated structure as an example, the reaming conditions and accuracy requirements of the laminated structure are as follows:
[0029] (1) Structural geometric parameters of the reamer: the diameter is 6.6mm, the main deflection angle is 45 degrees, and the rear edge angle is 12 degrees;
[0030] (2) The tool material is K6UF (tungsten carbide);
[0031] (3) Reaming process parameters: cutting speed is 20m / min, feed rate is 0.03mm / r;
[0032] (4) Reaming hole size accuracy requirements: the hole size meets the H9 accuracy;
[0033] (5) The thickness of the T300 composite ma...
