The processing characteristics of the inner hole of the cast aluminum alloy box are that the blank has a bottom hole and the unilateral processing margin is 1.5 mm.According to the characteristics of the blank,this paper adopts a more efficient radial expansion processing path to replace the cylindrical helix layer down processing path.In order to solve the problem of direct programming instruction without vortex lines in the numerical control system,a multi-segment semi-circular arc is innovatively used to fit the vortex lines with the help of the discretization idea to achieve the corresponding effect,and the feasibility and accuracy of the fitting strategy are verified from the perspective of geometric intuition and analytic expression.
