摘要:
微小型元件在各种领域中都起着至关重要的作用,其加工过程就显得尤为重要。本文以高速微细铣削实验为基础,研究了微细铣削过程中刀具磨损的机理。验证了切削用量三要素中的切削速度这一单一要素的改变对刀具磨损产生的影响,根据实际实验获得的数据和现象进行分析,并得出结论:高速微铣削过程中,在不改变其他条件下,一定范围内切削速度对刀具的影响符合传统加工的规律,即切削速度越大,刀具磨损得越严重,刀具的寿命越短,而超过这一速度的上限值,刀具磨损就相当大。
Abstract:
The microminiature element plays an important role in various kinds of fields, and its processing is par-ticularly important. Based on high speed micro milling experiment, this paper studies the tool wear mechanism of the micro milling process, and verifies that the change of the cutting speed, one of the three elements of cutting consumption, affects on the tool wear. Results of analysis and experiment draw the conclusion: in the high speed micro milling process, not changing the other conditions and in a certain cutting speed range, the effect of the cut-ting speed on tool wear is corresponded with the traditional milling processing law, that is, the greater the cutting speed, the more serious the tool wear and the shorter the life of the tool; however, the tool wear is quite serious if the cutting speed exceed the upper limit value.
