Abstract
This application discloses a milling method for multi-angle thin-walled parts, including the following steps: roughing the part, reserving preset allowances for dimension surfaces A, B, and F, through holes P and Q, and datum surface C; mounting the part on a fixture, with dimension surfaces D and E on the part respectively engaging with the first pre-mounting surface H and the second pre-mounting surface I on the fixture, and the datum surface C extending beyond the fixture by a greater than the preset allowance; mounting the fixture on the chuck of a machining center and machining the datum surface C; rotating the fixture 180° and machining dimension surface A; rotating the A-axis of a four-axis machine tool to an angle of α° and machining the dimension surface F of through hole P; rotating the A-axis of the four-axis machine tool to an angle of β° and machining the dimension surface B of through hole Q. This application has the advantages of convenient clamping and high machining efficiency.
