對於機械加工而言,切削加工一直以來都具有很重要的地位。為了能達到良好的切削效果,加工機、控制系統與刀具必須彼此配合相輔相成。當遇到切削狀況不理想時,最簡便的方法便是調整切削參數,以達到良好的切削效果。
鑽削加工中,經常會遭遇到顫振問題,當顫振發生時,對於刀具壽命與加工精度皆有不良影響。並且,顫振對於鑽削而言容易產生不連續切屑,使得深孔鑽削切屑排除更為不易,進一步增加切削阻抗。對於強度較低之微小鑽頭容易造成破壞。
鑽削加工過程中,將會因使用的加工機、切削參數與鑽頭直徑的不同而產生不同程度的顫振,而造成切削參數調整上的困難。因此,本文採用二階反應曲面法,對於不同直徑之微小鑽頭進行深孔加工實驗,以得到微小鑽頭使用不同鑽削加工參數進行深孔加工時,鑽削參數與顫振關係。而以實驗方法將可以避免大量公式計算,僅需少量的實驗即可得到切削參數調整之方向。
Cutting always is a very important position in the purposes of machining. Machine, tools and control system must be complementary with each other, in order to achieve good cutting results. When the situation is not ideal in metal cutting, the easiest way is to adjust the cutting process in order to achieve good cutting results.
Drilling is often the problem encountered chatter. Chatter have an adverse impact on tool life and machining accuracy. For the purposes of drilling chatter prone to discontinuous chip and will brought deep hole drilling chip more difficult to rule out possibility, and a further increase in cutting resistance. For the small twist drills will easily damage.
In drilling, there will have different degrees of chatter when use different of the machine, cutting process and diameter. That is difficult to adjust the cutting process. In this paper, the second order response surface methodology would be used for different diameter small drills experiments carried out deep-hole drilling, for obtain drilling process and the relationship between chatter. That can be avoided to a large number of calculate process, only a small number of experimental process, in order to adjust cutting process.
