Title:
DOUBLE-ROW GROOVE PLUNGE MILLING PROCESSING METHOD FOR USE WITH INTEGRAL IMPELLERS
Document Type and Number:
WIPO Patent Application WO/2018/145349
Kind Code:
A1
Abstract:
A double-row groove plunge milling processing method for use with integral impellers, comprising: planning a double-row plunge milling cutter path along two side blades of an impeller flow channel, a cutter arrangement sequence of the cutter path following the direction of an inlet and outlet of the flow channel; determining cutter diameter according to the width of a bottom portion of a cross-section of the flow channel and segmenting the flow channel, the width of a bottom portion of a cross-section of each segmented flow channel being greater than one times the cutter diameter and smaller than two times the cutter diameter. Compared with existing methods for cutting large feed layers, the present invention may increase rough-processing efficiency of integral impellers by more than 50%, while facilitating the elimination of plunge milling cutter ejection, and effectively reducing redundant cutter paths, the implementation process being simple and facilitating computer-aided manufacturing (CAM) software integration.
