During the micro-hole machining process of molds, it should be avoided to have issues such as expanded hole diameters, excessively large hole straightness, poor surface roughness of the workpiece, and rapid wear of the drill bit, to prevent affecting the quality of the drilling and increasing processing costs. It is recommended to ensure the following technical requirements as much as possible.

1. Dimensional Accuracy: Precision of hole diameter and depth dimensions.
2. Shape Accuracy: Hole roundness, cylindricality, and axis straightness.
3. Positioning Accuracy: coaxiality of hole to hole axis or hole to outer circle axis
4. Parallelism and perpendicularity between holes and holes, or between holes and other surfaces.

Additionally, the following 5 factors should be considered:
1. Hole diameter, depth, tolerance, surface roughness, and hole structure;
2. Structural features of the workpiece, including clamping stability, overhang, and rotational capabilities.
3. Machine tool power, speed, coolant system, and stability
4. Processing Quantity
5. Processing Costs.
