Abstract
The invention provides a machining method of H-shaped thin-wall parts. The machining method includes steps of selecting tools in various machining stages and sequentially placing the tools into cutter discs; positioning workpieces to be machined by axial fastening reference; setting linear speed and cutting feed of rotation of a spindle of a numerical-control machine tool, clamping parts, aligning the blank ends of two parts to the end faces to form blank components, arranging a cushion block between two jaws of a vice, arranging the blank components on the cushion block and adjusting height of the cushion block so as to enable the blank components to be higher than the upper ends of the jaws of the vice by one fourth of height of the parts, and rotating and tightening screws to enable the jaws of the vice to clamp the blank component. By the machining method of H-shaped thin-wall parts, deformation of thin-wall parts due to the fact that a soft jaw or vice directly clamps thin-wall bases during milling is eliminated, machining procedures of the parts are simplified and parts are machined in pairs.
