Such as five-axis linkage machining centers, to meet the high precision requirements.

Secondly, choose tools suitable for the material and machining process, such as high-speed steel or carbide tools, to improve the machining efficiency and surface quality.

At the same time, focus on the wear resistance and service life of the tool. Use an intelligent software system to optimize the machining parameters.

This will ensure the efficient and stable operation of the production process.

3. Reasonable planning of the machining path

In CNC programming, in-depth analysis and understanding of the geometry of the mold is required to determine the best machining path.

By carefully planning the machining path, the path length of tool movement can be minimized, reducing unnecessary downtime.

This planning needs to take into account the distribution of cutting forces and cutting heat, especially when machining harder materials.

Reasonable machining path planning can balance these factors and avoid problems such as localized overheating, deformation, or fracture of the material.

In addition, reasonable machining path planning also needs to consider the quality requirements of the mold surface.

In mold manufacturing, the surface of the mold usually needs to be finely processed to meet certain precision and finish requirements.

By optimizing the machining path, the surface quality can be maximized, avoiding unnecessary repeated processing or grinding, thus improving processing efficiency and quality.

Reasonable planning of the machining path is one of the important application strategies of CNC machining technology in mold manufacturing.
