The taper hole shown in Fig. 1 is made of LD10CS, and a key groove with a width of 4 mm is inserted. The tapered contact hole and the gauge colored contact area are not less than 70%, and the roughness of the tapered hole is R_a0.8. In the past, the car-to-plug processing method was adopted. Because the machining of the car is affected by the accuracy of the machine tool, the clamping deformation and the unevenness of the hand feed, the colored contact area of ​​the taper hole does not meet the requirements. A small amount of material is squeezed near the keyway after the slot to make the colored area
