CNC five axis machining dry goods: Understanding which parts are suitable for this process in one article

1、 Why do designers always ask: which parts are suitable for CNC five axis machining?

With the increasing demand for component complexity and processing consistency in industrial manufacturing, five axis machining has become a widely used process choice in the field of precision manufacturing due to the advantages of digital control. Especially in the field of robot core component manufacturing, five axis linkage has become the mainstream solution. Many procurement and design personnel first ask when developing new products: What parts require five axis machining? Is the part in my hand suitable for five axes? Today, we will combine industry experience to sort out what parts are suitable for five axes and help you quickly determine the machining plan.

2、 Understand the process characteristics first, and then judge the compatibility of the parts

To determine whether a component is suitable for five axis machining, it is first necessary to understand the process characteristics of five axis machining itself. Five axis linkage is achieved through digital program control of tool movement to complete cutting of metal blanks. Its core advantages lie in strong processing flexibility, high consistency, no need for complex mold opening processes, and the ability to quickly produce small batches. It is suitable for research and development samples and mass production orders of multiple varieties and small batches.

Compared to three-axis machining, five axis machining can complete the machining of multiple curved angles at once without the need for multiple clamping adjustments. It has stronger machining efficiency and structural adaptability, and has more obvious advantages for complex and irregular parts. It is also suitable for the diverse needs of five axis machining of robot parts. From the perspective of process adaptability, as long as the requirements of machinability and appropriate blank size are met, the vast majority of mechanical parts can be processed using five axis machining. However, from the perspective of cost and efficiency, the following types of parts choose five axis machining for the highest cost-effectiveness.

3、 After reading these five categories, you will know which parts are suitable for five axis machining

1. Core structural components of robots

The field of robotics is currently widely used in five axis machining. The structural parts of robots, such as joint shells, connecting seats, and arm rods, are mostly irregular structures with high design requirements for multi-faceted and multi curved surfaces, making them very suitable for five axis linkage machining. These types of parts often require design adjustments based on different robot models, with small batch sizes and frequent design changes. Five axis machining does not require mold opening, and only requires modifying the machining program to adapt to new designs, perfectly matching the R&D iteration needs of the robotics industry.

Real case: When Shenzhen Huiwen Zhizao was processing a joint shell for a certain technology enterprise, the part contained 4 different angle mounting holes and 2 arc-shaped weight reduction grooves. The three-axis solution required 3 clamping tolerances to accumulate 0.08mm, which was controlled within 0.02mm after changing to a single clamping for five axes, saving subsequent rework costs.

2. Complex irregular surface parts

Parts with complex irregular surfaces, such as mold cavities, irregular camshafts, and streamlined structural components, are difficult to accurately form using conventional machining methods. However, CNC five axis machining can accurately reproduce the surface shape of design drawings through continuous tool path control. These types of parts are typical adaptation objects for CNC five axis machining. In the processing of robot shells and special-shaped transmission parts, this type of structure is very common. CNC five axis machining can complete all surface machining in one clamping, avoiding errors caused by multiple clamping and improving the overall consistency of the parts.

3. Polyhedral porous parts

Parts that require machining holes and slots on multiple surfaces at different angles, if using ordinary machining methods, require multiple flips for clamping, which not only has low efficiency but is also prone to clamping errors. CNC five axis machining can adjust the workpiece angle through a turntable and complete all surface machining at once, which is very suitable for the machining of polyhedral parts such as robot connecting flanges, mounting bases, etc. Most of them have this type of structure, and the efficiency and accuracy of CNC five axis machining are better.

4. Small batch customized parts

For parts that require R&D sampling and multi variety small batch production, the cost of mold opening injection molding or casting is high and the cycle is long. However, five axis machining only requires importing drawings for direct processing, and samples can be delivered in a few days. Whether it is one sample or several hundred pieces for mass production, it can be adapted and cost control is more flexible. Many technology innovation oriented enterprises choose CNC machining of robot joint parts for sample verification during the new product development stage, to quickly validate design solutions and shorten the research and development cycle.

5. High hardness and difficult to machine parts

For some parts made of difficult to machine materials such as high hardness alloys and stainless steel, ordinary machining is difficult. However, 5-axis can control cutting parameters through programs and complete stable cutting with specialized tools, which can better ensure machining quality and is suitable for the production of such material parts. Many load-bearing structural parts of robots are made of high-strength steel, which is very suitable for five axis machining to complete production.
