1、 What is the difference between four axis engraving machine and five axis engraving machine

普通雕刻機只有XYZ三個軸，同過在XYZ三軸上添加多一個旋轉軸的雕刻機稱為四軸雕刻機，添加兩個旋轉軸的雕刻機叫五軸雕刻機。

The ordinary engraving machine has only three XYZ axes. The engraving machine with one more rotation axis on the XYZ three axis is called four axis engraving machine, and the engraving machine with two rotating axes is called five axis engraving machine.

四軸雕刻機有三種不同的添加旋轉軸，分別為A、B、C三種，A軸是繞X軸旋轉的軸，以此類推B軸對應Y軸，C軸對應Z軸。ABC這三個旋轉軸又叫做分度頭，四軸雕刻機即是三軸雕刻機上添加了一個分度頭，具體是添加在哪一條坐標軸上就看客戶需求了。

Four axis engraving machine has three different adding rotation axes, which are a, B and C. axis A is the axis that rotates around X axis, and so on, b axis corresponds to y axis, and C axis corresponds to Z axis. ABC's three axes of rotation are also called dividing heads. The four axis engraving machine adds a dividing head to the three-axis engraving machine. The specific axis to be added depends on the customer's requirements.

五軸雕刻機跟四軸雕刻機有點相似，但是又不完全一樣。五軸雕刻機也是添加分度頭，但是也添加兩個，而且還是在裝機過程中才能添加，意思就是無法在一臺完整的三軸雕刻機上直接添加到XYZ三個軸上。

Five axis engraving machine is similar to four axis engraving machine, but it is not exactly the same. Five axis engraving machine is also added dividing head, but also add two, and it can be added in the process of installation, which means that it can not be directly added to XYZ three axes on a complete three axis engraving machine.

與四軸雕刻機同理，五軸雕刻機只不過是在ABC三個旋轉軸上選其中兩個，可以是AB、AC、BC。正是因為五軸雕刻機旋轉軸比四軸雕刻機多一個，所以五軸雕刻機能加工的工件四軸雕刻機不一定能加工，而四軸雕刻機能加工的工件五軸雕刻機卻可以加工。

Similar to the four axis engraving machine, the five axis engraving machine only selects two of the three rotation axes of ABC, which can be AB, AC and BC. It is precisely because the rotation axis of five axis engraving machine is one more than that of four axis engraving machine, so the workpiece processed by five axis engraving machine may not be able to process, while the workpiece processed by four axis engraving machine can be processed by five axis engraving machine.

四軸雕刻機通過一個旋轉軸跟XYZ三個直線軸實現聯動可以加工一些簡單的曲面，而五軸雕刻機比四軸雕刻機多了一個分度頭，所以可以通過兩個旋轉軸和XYZ三個直線軸實現聯動，加工更復雜的空間曲面。我們鼎亞精機的所有型號的雕刻機都可以選配四軸或五軸。

Four axis engraving machine can process some simple surfaces through a rotation axis and XYZ three linear axes, while five axis engraving machine has one more dividing head than four axis engraving machine, so it can realize linkage through two rotating axes and three linear axes of XYZ to process more complex space surface. All types of engraving machines of Dingya precision machine can be equipped with four or five axes.

二、四軸雕刻機和五軸雕刻機編程有什么區別

2、 What is the difference between four axis engraving machine and five axis engraving machine programming

在編程方面，四軸雕刻機的編程跟五軸雕刻機的編程是有較大的區別的，四軸雕刻機加工工件時，刀軸始終是朝著工件旋轉軸心線的，編程跟三軸雕刻機比較相似。

In terms of programming, there is a big difference between the programming of four axis engraving machine and that of five axis engraving machine. When the four axis engraving machine processes the workpiece, the cutter axis always rotates toward the axis line of the workpiece, and the programming is similar to that of the three axis engraving machine.

五軸雕刻機加工工件時，由于刀具和工件在相互位置加工過程中隨時調整，例如加工螺旋槳一片時，為了得到比較好的表面質量，那就需要刀具和葉片表面夾角始終保持一致，也就是說刀軸方向不斷改變，經常需要手工進行刀軸的插補，在加工這些復雜的空間曲面時要考慮的參數比四軸雕刻機編程時多得多，而且對數控系統有較高的要求，如果使用一般的數控系統還會增加編程難度，影響機床精度，大多數五軸雕刻機使用的是三菱或者發那科的數控系統，而四軸雕刻機則沒有這么高的要求。

When a five axis engraving machine processes a workpiece, because the tool and the workpiece are adjusted at any time in the process of processing, for example, when processing a piece of propeller, in order to obtain a better surface quality, the angle between the tool and the blade surface should always be consistent, that is to say, the direction of the cutter shaft is constantly changing, so it is often necessary to manually interpolate the cutter shaft to process these complex spatial surfaces The parameters to be considered are much more than the four axis engraving machine programming, and there are higher requirements for the CNC system. If the general CNC system is used, the programming difficulty will be increased and the accuracy of the machine tool will be affected. Most of the five axis engraving machines use the CNC system of MITSUBISHI or fanco, while the four axis engraving machine does not have such high requirements.
