New perspectives on the cutting mechanism of difficult - to - machine materials
難加工材料切削機(jī)理研究的新進(jìn)展
The cutting experiments for difficult - to - machine materials have shown that the cutting rate can be increased much more , the surface quality improved and the probability of wire - breaking reduced
對難加工材料的切割實(shí)驗(yàn)表明：復(fù)合工藝能較大幅度地提高加工效率，改善表面質(zhì)量，降低斷絲概率。
Compared with the existing rp methods using high energy density beams , the hpdm method solved the key problems of insufficient dimensional precision and surface quality caused by the step effect and no - supporting , and puts forward a new way to directly manufacture the difficult - to - machining materials parts with short - routine , low - cost and high quality
該技術(shù)解決了現(xiàn)有高能束熔積成形技術(shù)因無支撐和臺階效應(yīng)造成的尺寸精度和表面質(zhì)量不高的瓶頸問題，是難加工材料零件短流程、低成本、高質(zhì)量無模精確制造的新的有效加工方法。
