War God Advantages of Five-Axis Machining Centers in Composite Mold Processing

The five-axis machining center for composite materials is a very important part of numerical control machining. This technology has been widely applied in high-precision equipment manufacturing fields such as ships, aerospace, automobiles, and new energy. In traditional mold processing, three-axis machining centers and vertical machining centers are commonly used to complete the milling processing of workpieces. With the continuous development of mold manufacturing and processing technology, some weaknesses of traditional vertical machining centers and three-axis machining centers have gradually emerged. At present, ball-end mills are widely used in mold processing. Although the advantages of using ball-end mills in mold processing are obvious, if vertical machining centers are applied, the linear speed of the bottom surface is zero and the surface finish is also poor. However, by processing molds with five-axis machining centers, all the above shortcomings can be completely overcome.

01 Introduction to Five-Axis Machining Centers

Five-axis machining is the addition of two rotary axes on the basis of having three axes. Three linear axes + two rotary axes, A and C axis pendulum head structure

● Tool position points (X,Y,Z) and tool axis vectors in five-axis machining

Five-axis machining centers, taking advantage of their high precision, can produce high-precision curved surfaces and achieve multi-face processing with a single clamping.

02 Five-axis machining mold process

● Processing of the blank:

For large cutting volumes, pay attention to combining layer priority with depth priority during processing.

● Blank processing sequence

When performing rough machining, start with the back and the periphery.

After rough machining the cavity, remove the workpiece to release the stress.

▶ Rib treatment during the fine processing of the cavity

When processing long and narrow molds, pay attention to the clamping method.

Semi-finishing and finishing

When performing fine processing, measures such as cutting boundaries are adopted to control the processing area.

Combining multiple tool path processing methods.

The design of the knife path should avoid the knife passing over steep sections.

▶ Make rational use of the optimization function of the cutting layer.

● Segmented surface processing

When programming deep cavity molds, the rigidity of the cutting tools should be taken into account, and the processing should be carried out in segments. For different curved surfaces, the rational use of functions should be optimized.

● Smooth surface processing

When a three-axis machine tool is processing a relatively gentle curved surface, the linear velocity of the center rotation of the ball-end tool is almost zero during the processing of the curved surface, which has a significant impact on the tool.

When a five-axis machining center is processing gentle curved surfaces, the tool can be placed at a certain Angle according to the position of the workpiece for processing.

03 Advantages and Applications of Five-Axis Machining

● Processing of inclined holes on inclined surfaces

▶

The three-axis machine does not have this function. For such workpieces, they can only be processed in sequence.

The five-axis machining center can accurately process holes in the vertical position of the workpiece's inclined surface through the spindle swing head processing action.

● Side wall processing

When performing three-axis machining, the issue of vibration control for extended tools will make it difficult to guarantee the quality of the workpiece.

Five-axis machining centers are suitable for processing angled side walls. During the processing, they can avoid the formation of rib patterns due to the milling cutter's processing of inclined surfaces in three-axis machining, solving multiple technological limitations of three-axis machining and enabling the surface quality of molds to easily meet the expected requirements.

● Processing of small inclined steps

The side wall has difficult-to-machine parts such as small inclined steps

It is very difficult to achieve precise machining in three-axis machining, and the machining process takes a lot of time.

When performing five-axis machining, by selecting the optimal tool axis processing Angle, the side wall steps can be completely milled in one go. (The above article is compiled from the Internet
