Embodiment 1
[0049] The material used in this embodiment is GH4169 alloy. Such as Figure 5 shown in the following steps:
[0050] The first step, model preparation
[0051] The three-dimensional model of the rudder shaft is processed, and the three segments are summed as a whole, and a margin of 2 mm is added to the outer surface of the long end and short end of the rudder shaft, and a margin of 0.5 mm is added to all inner profiles. Add a 0.1mm deep "U"-shaped reference line around the surface of the rudder shaft as a line drawing reference for finishing. According to the structural characteristics and forming direction of the rudder shaft, a solid process support is added at the bottom of the long end of the rudder shaft. The thickness of the solid body is 20mm. Multiple diamond-shaped hollow supports are added to the solid body to improve the forming efficiency and powder utilization rate.
[0052] The second step, slice file preparation
[0053] Import the processed part model int...
