The use of short cutting tools is the main feature of five-axis machining. Short tools will significantly reduce tool deviation, thereby obtaining a good surface quality, avoiding rework, reducing the amount of welding rod used, and shortening the processing time of EDM. When considering five-axis machining, the goals of using five-axis machining molds must be considered:
Use the shortest cutting tool possible to complete the processing of the entire workpiece. It also includes reducing programming, clamping and processing time but can get a more perfect surface quality.
As long as the workpiece cavity is not very deep (relative to the tool diameter), a three-axis tool path (2, 3, 5) is sufficient. If the workpiece cavity is very deep and has very narrow parts, it is not enough to use a pure three-axis tool path to complete the entire finishing. この場合, poor surface quality and long processing time ensue. 形 1 is the case of a three-axis tool path. Here, the shortest tool must be very long in order to be able to machine all areas of the workpiece in the vertical direction.

When using a shorter tool, the spindle should be tilted to ensure that the special area of the workpiece can be processed. 3+2 axis machining is usually considered as setting a constant angle to the spindle. Complex workpieces may require many oblique views to cover the entire workpiece, but this will cause tool paths to overlap and increase machining time.
加えて, all the oblique views are difficult to accurately combine, so the workload of manual polishing will increase, そして同時に, it will greatly increase the movement in and out, which often leads to surface quality problems and more tool movement.

This area still needs an additional oblique view.

の欠点を克服するために、 3+2 軸加工, 5 軸同時加工の方が良い選択かもしれません, 言うまでもなく、一部の 5 軸工作機械には、金型業界向けに特別に設計された機能もいくつかあります。. 5軸連動加工は直線3軸と回転軸2軸を連携させて同時に動かすことができます。, 3軸の問題をすべて解決し、 3+2 軸加工. ツールは非常に短い場合があります, ビューの重複はありません, 加工領域を取りこぼす可能性が低くなります, 追加のインポートやエクスポートを行わずに処理を継続的に実行できます。 (図を参照 3).
