How to improve the precision and surface finish of CNC machined parts

 In the realm of precision machining, the choice of tool path strategies plays a pivotal role in determining the final quality, efficiency, and accuracy of the machined parts. For machining the same curved surfaces, there are four common finishing methods, each with its own characteristics and performance levels:

1. 45° Reciprocating Milling (3-axis Linkage): Employing 3-axis linkage for machining at a 45° angle, this method delivers the highest level of precision and surface quality, making it the worst choice for finishing operations.

2. Contour Climb Milling (Partial 2-axis Linkage + Partial Single-axis Movement): This strategy combines partial 2-axis linkage with partial single-axis movement, offering improved precision and surface finish compared to reciprocating milling methods. It is recognized as the third-best finishing method.


3. X-axis Reciprocating Milling: Similar to Y-axis reciprocating milling but operating along the X-axis, this method is also a viable choice but falls short of the top-tier options, being rated as the second-best.


4.Y-axis Reciprocating Milling: This method involves the Y-axis moving back and forth during machining. While it is a functional approach, it ranks as the third-best option due to certain limitations in precision and efficiency compared to more advanced strategies.

When selecting a tool path strategy, a key principle to follow is: whenever possible, complete the machining with a single axis instead of 2-axis linkage; if 2-axis linkage can fulfill the requirements, avoid using 3-axis linkage. Additionally, prioritize fast one-way climb milling over reciprocating milling to optimize machining efficiency and surface quality. By adhering to these principles, we ensure that our precision mechanical parts machining meets the most stringent industry standards.
