The dimensional accuracy control and measurement method of agricultural machinery aluminum forgings is to ensure that the geometry and size of the forgings meet the design requirements to ensure its assembly performance and working effect. The following are some commonly used dimensional accuracy control and measurement methods:
- Design control: In the design stage, the dimensional tolerance of agricultural machinery aluminum forgings is reasonably determined to meet the assembly requirements and functional requirements. According to specific needs, tolerance superposition method or statistical tolerance distribution method can be used.
- Processing control: In the processing of aluminum forgings, through strict control of process parameters, such as forging temperature, mold size, cooling methods, etc., to control size changes. The use of advanced CNC machine tools and advanced cutting tools can improve the machining accuracy.
- Measuring tools: Select appropriate measuring tools and equipment to measure dimensions, such as micrometer, vernier caliper, outside diameter measuring instrument, coordinate measuring instrument, etc. Ensure that the measuring tool accuracy meets the requirements and is calibrated and maintained regularly.
- Standard sample: Use standard sample to check the dimensional accuracy of aluminum forgings. According to the design requirements, the appropriate standard sample is made and compared with the aluminum forgings to evaluate whether the dimensional accuracy meets the requirements.
- Non-contact measurement: The use of optical projectors, laser scanners and other non-contact measuring equipment can achieve high-precision dimensional measurement, while avoiding the impact of measuring tools on measurement results.
Dimensional accuracy control and measurement methods need to be combined with the specific shape and requirements of agricultural machinery aluminum forgings to determine, but also need to consider the feasibility and economy of the production process. It is recommended to communicate and cooperate with professional engineers or measurement experts in practical applications to ensure the control of dimensional accuracy and the accuracy and reliability of measurement.
