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

普通雕刻机只有XYZ三个轴，同过在XYZ三轴上添加多一个旋转轴的雕刻机称为四轴雕刻机，添加两个旋转轴的雕刻机叫五轴雕刻机。

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.

四轴雕刻机有三种不同的添加旋转轴，分别为A、B、C三种，A轴是绕X轴旋转的轴，以此类推B轴对应Y轴，C轴对应Z轴。ABC这三个旋转轴又叫做分度头，四轴雕刻机即是三轴雕刻机上添加了一个分度头，具体是添加在哪一条坐标轴上就看客户需求了。

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.

五轴雕刻机跟四轴雕刻机有点相似，但是又不完全一样。五轴雕刻机也是添加分度头，但是也添加两个，而且还是在装机过程中才能添加，意思就是无法在一台完整的三轴雕刻机上直接添加到XYZ三个轴上。

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.

与四轴雕刻机同理，五轴雕刻机只不过是在ABC三个旋转轴上选其中两个，可以是AB、AC、BC。正是因为五轴雕刻机旋转轴比四轴雕刻机多一个，所以五轴雕刻机能加工的工件四轴雕刻机不一定能加工，而四轴雕刻机能加工的工件五轴雕刻机却可以加工。

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.

四轴雕刻机通过一个旋转轴跟XYZ三个直线轴实现联动可以加工一些简单的曲面，而五轴雕刻机比四轴雕刻机多了一个分度头，所以可以通过两个旋转轴和XYZ三个直线轴实现联动，加工更复杂的空间曲面。我们鼎亚精机的所有型号的雕刻机都可以选配四轴或五轴。

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、四轴雕刻机和五轴雕刻机编程有什么区别

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

在编程方面，四轴雕刻机的编程跟五轴雕刻机的编程是有较大的区别的，四轴雕刻机加工工件时，刀轴始终是朝着工件旋转轴心线的，编程跟三轴雕刻机比较相似。

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.

五轴雕刻机加工工件时，由于刀具和工件在相互位置加工过程中随时调整，例如加工螺旋桨一片时，为了得到比较好的表面质量，那就需要刀具和叶片表面夹角始终保持一致，也就是说刀轴方向不断改变，经常需要手工进行刀轴的插补，在加工这些复杂的空间曲面时要考虑的参数比四轴雕刻机编程时多得多，而且对数控系统有较高的要求，如果使用一般的数控系统还会增加编程难度，影响机床精度，大多数五轴雕刻机使用的是三菱或者发那科的数控系统，而四轴雕刻机则没有这么高的要求。

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.
