1. Requirements for process personnel: Only an experienced process personnel can develop a scientific, precise, and efficient process flow. The process flow is the guiding standard for precision parts processing and the basis for CNC programming. Poor craftsmanship, the entire factory is busy!

2. Requirements for equipment accuracy: The accuracy of the selected processing equipment itself should meet the accuracy requirements for precision parts processing. If the accuracy of the processing equipment cannot meet the requirements, it will not be possible to produce precision parts that meet the requirements.

3. Requirements for operators: Operators are technical engineering personnel who are directly engaged in on-site operations and need to strictly follow the process flow. They should have the most basic equipment, fixture and tool operations, rich experience, and strong hands-on ability. Able to effectively solve problems.

4. Requirements for measuring tool inspection: The quality of measuring equipment directly affects the inspection results of precision parts. If the measuring equipment cannot detect the required tolerance accuracy. So it does not have the ability to evaluate precision parts, let alone provide engineers with quality improvement directions and data.

5. Requirements for materials: Materials have significantly different requirements for precision parts processing, and different materials have different processing performance. There are also different requirements for processing parameters. We need to select appropriate cutting tools, revolutions, feed rates, and various processing parameters based on the processing performance of the material.

6. Requirements for tolerance accuracy: The level of tolerance accuracy directly affects the selection of processing technology, processing equipment, and processing parameters. This requires our process engineers and operators to have a quantitative and accurate grasp of tolerance accuracy. Only then can precision parts that meet the requirements be processed.

7. Environmental requirements: The processing environment refers to the environment where the machine equipment workshop is located, which must meet the requirements for precision parts processing. Sometimes, there is excessive vibration, noise, air cleanliness, and dust on the floors. Temperature and humidity can both affect the accuracy and stability of precision parts processing.
