5-eksen frezeleme paslanmaz çelik

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. Bu durumda, poor surface quality and long processing time ensue. Figür 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.
Ek olarak, all the oblique views are difficult to accurately combine, so the workload of manual polishing will increase, ve aynı zamanda, it will greatly increase the movement in and out, which often leads to surface quality problems and more tool movement.

Figür 2 demonstrates four workpiece views, but there is still an area in the center of the workpiece that cannot be covered. This area still needs an additional oblique view.

Eksikliklerin giderilmesi için 3+2 eksen işleme, beş eksenli eşzamanlı işleme daha iyi bir seçim olabilir, Bazı beş eksenli takım tezgahlarının ayrıca kalıp endüstrisi için özel olarak tasarlanmış bazı işlevlere sahip olduğundan bahsetmiyorum bile.. Beş eksenli bağlantı işleme, üç doğrusal ekseni ve iki döner ekseni aynı anda hareket ettirecek şekilde koordine edebilir, 3 eksenli tüm sorunları çözen ve 3+2 eksen işleme. Araç çok kısa olabilir, görüşlerde örtüşme yok, İşleme alanını kaçırma olasılığı daha azdır, ve işleme, ek ithalat ve ihracat gerekmeden sürekli olarak gerçekleştirilebilir (Şekil'e bakın 3).
