中文摘要
本研究應用田口法,針對馬鞍型拋物曲面結合電腦輔助設計與製造實際切削加工出工件,再以各採樣方法由接觸式三次元量測儀量得工件幾何公差中曲面輪廓度,去分析影響切削的主要原因、尋求最後的曲面切削條件;並去探討量測過程中影響量測精確度的各因子貢獻率。
以下具體的研究成果期盼能提供給職業教育學界,往後在有時間限制的加工與量測實習課程教學過程中有所依據,不用花太多時間去try and error而提高實習課程的效益。
1.由目前大部分切削文獻中以探討影響切削的因素為主。而本論文藉由田口法切削實驗可以得知影響馬鞍型拋物曲面切削加工過程中,以主軸轉速的因素最為顯著,貢獻率高達59.38%。
2.由文獻中目前對於曲面的量測的研究,大都只限於圓、球或錐體物件的探討。而本文則針對同時具有凹凸規律特徵的馬鞍型拋物曲面量測做探討,將曲面量測技術再往前跨出一步。
3.發現對於同時具有規律凹凸馬鞍型的曲面,使用隨機採樣便可得到誤差最小的曲面輪廓度,沒有使用HSS或LHS定座標點位置的困擾,可縮短時間與減少花費。
4.由田口法量測實驗中,從變異分析表中發現採樣面積的影響佔
第一位,採樣法的選擇貢獻率僅佔3.46%。
Abstract
ABSTRACT
This research uses Taguchi Method, combined with Computer Aided Design and Manufacturing, processing the work piece into the saddle type. Next, diverse sampling methods are applied to measure the profile of surface with Coordinate Measuring Machine, with an aim to analyzing the main factors that influence cutting and seeking the last conditions for cutting out the curved surface; in addition, I will probe into the contribution rate of each factor which influences the precision during the process of measurement.

The following results of this research are expected to be offered to the circles of vocational education as a basis of processing and measuring instruction. In this way, it will not take too much time to try and error and therefore, the practice course can be more efficient.

1. With reference to the documents that are focused on the factors affecting the cutting, this thesis, by means of Taguchi Method, shows that during the process of cutting saddle-type curved surface, the rotating speed of the axle is the most influential, whose contribution rate is 59.38%.

2. Since most documents are on circles, balls or cone objects, this thesis will aim at the measurement of saddle-type curved surface, with an intention to further the measuring technique.

3. It is found that as to the saddle-type curved surface, random sampling can get the profile of surface with minimal errors, and has no such trouble as using HSS or LHS, which can reduce time and cost.

4. In the experiment of Taguchi Method, according to analysis of variance, the influence of the sampling area is the greatest while the choice of sampling method only contributes to 3.46%.
