METHOD OF BLANK MILLING WITH VARIABLE ALLOWANCE

摘要

FIELD: mechanical engineering. SUBSTANCE: prior to machining, section with maximum allowance is determined on blank, and value of contact area of milling cutter and blank is calculated for it. When machining of this section milling cutter axis is set perpendicularly to direction of feed. When machining the remaining sections of blank surface end milling cutter rake is determined preliminarily for every section so that contact area of working surface of end milling cutter and blank on given section is equal to contact area of end milling cutter working surface and blank on section with maximum allowance. EFFECT: more efficient machining of parts. 4 dwga
