Five-axis machining principle of CNC prototype
Speaking of CNC prototype processing services, you will definitely think of 5-axis CNC prototype processing. Choosing the right processing plan will lead to consumer victory.
CNC prototype processing is a program used in most manufacturing operations and is commonly used in most industries. CNC stands for computer digital control, and handles the use of one or more computers to manage the operation of different machine tools (such as lathes, routers and milling machines).
5-axis CNC prototype processing is an absolutely excellent CNC prototype processing, which can be used to consume parts and final products from a variety of materials such as plastics and metals.
However, sometimes detailed 5-axis CNC prototype processing is mentioned. Most people's first impression is: high technology, expensive, and difficult to operate, but is 5-axis processing really like this? The following paragraphs will introduce you to 5-axis CNC prototype machining from 3 important aspects.

1. What is five-axis machining
This is a program that involves using CNC to move cutting equipment or different parts on five different axes at the same time. This provides space for the consumption of very complex parts, which is why 5-axis CNC milling is very common in aerospace operations. One of the biggest dedications to the use of 5-axis CNC prototype processing machine tools is the need to improve proficiency and reduce the consumption time from the beginning to the completion of the practical process.
The ability of the rotating table or cutting tool to prevent collisions with fixed equipment parts can provide space for quickly approaching the geometric shape of the parts is another influencing factor. Finally, through the rotating table or cutting equipment to maintain the best cutting position and different chip load, thereby improving the life or life of the equipment.
1.1 "5" of 5-axis machining
Five-axis machining is a way of CNC machining. The machining center we usually use is a three-axis machining center. The 3-axis refers to the X-axis, Y-axis, and Z-axis of the machining center. The five-axis machining center adds two rotation axes to the three common linear axes X, Y, and Z. These two axes are also called the fourth axis and the fifth axis. Two of the three axes A, B and C have different motion modes in the vertical machine to meet the technical requirements of various products.
1.2 Five main ways of five-axis machine
There are a wide variety of five-axis machine tools for horizontal machining centers, and there are mainly the following five methods: One is the double-slewing head mode, two rotating coordinates directly control the direction of the tool axis; 2. The pendent rotating head mode, the two coordinate axes are on the top of the tool , But the rotation axis is not perpendicular to the linear axis; the third is the double turntable mode, two rotating coordinates directly control the space rotation; 4. The drooping table, the two axes are on the table, but the rotation axis is not perpendicular to the axis; the fifth is One pendulum and one revolution, two rotating coordinates, one on the tool and one on the workpiece.

1.3 Varieties of five-axis CNC machine tools
There are several operations that allow the 5-axis CNC prototype machining machine to save a lot of your time and enhance your current program. There are many types of these machines to meet the demands of the growing manufacturing industry from time to time. The common difference of 5-axis CNC hand plate processing machine tools is the arrangement of the rotation axis. They are divided into three different types, including head/head, table/table and table/head.
a. head/head
The rotation axis of this type of CNC hand plate processing machine tool is located at the head. They are made of 5-axis vertices located on a specific platform and moved by a fixed worktable to keep the workpiece in place. So you don't need to worry about tool intervention in the spindle head of the machine tool. This gives the apex a chance to move around a specific part, making the 5-axis CNC prototype processing machine the best choice for the consumption of large parts. Due to their design, they usually have limited movement in the axis of rotation and tilt.
b. table/head
In this type of machine setup, one axis of rotation is located in the turntable and the other is located in the head. The rotation axis is located at the head and the range is limited, while the rotation axis is located in the table and the range is not limited. Since the parts are placed on the rotating shaft, this arrangement is limited by the number of items it can consume. Compared with the head/head type, one way that this type of setting is slightly advantageous is that it can rotate the parts consistently without worrying about reaching specific limits.
c. table/table
Here, all the rotating shafts of the machine are located in the worktable, and the range of the rotating shafts is also restricted. The range of its rotation axis is not limited. Compared with other types, this type of machine layout has the smallest working range. Others are equipped with clear motors to make them work very fast.
1.4 Five-axis machining ≠ five-sided machining
5-axis machining is very different from 5-sided machining. Many people don't know this, and mistake 5-sided machining for 5-axis machining. There are 5 axes for 5-axis machining: x, y, z, a and b axis (or c). The x, y, z and a, b axes (or c) constitute 5-axis simultaneous machining. It is suitable for hook surface processing, special-shaped processing, hollow processing, punching, oblique hole, and oblique cutting. 5-sided machining is similar to 3-axis machining. Only five faces can be processed, special processing, beveled hole, bevel cut, etc. are not allowed.
