Strategies to deal with mold processing dimensional accuracy that does not meet the requirements
During the mold processing process, if the dimensional accuracy does not meet the requirements, it will seriously affect the quality of the mold and the production of subsequent products. The following is a detailed explanation from cause analysis to solution measures.
Reason analysis
Equipment factors
Insufficient precision of the processing equipment itself, such as machine tool guide rail wear, large spindle radial runout, etc., will lead to deviations in the tool motion trajectory and errors in processing dimensions. In addition, if the equipment is not calibrated in time after long-term use, it will also cause the processing accuracy to decrease.
Tool factors
Tool wear is a common problem. As the use time increases, the cutting edge of the tool becomes blunt and the cutting force increases, which will cause changes in the machining dimensions. In addition, incorrect tool installation, such as eccentricity, looseness, etc., will also affect the machining accuracy.
Process factors
Unreasonable processing technology formulation, such as improper selection of cutting amount, too fast feed speed or too large cutting depth, will cause the mold to vibrate, resulting in dimensional deviations. In addition, unreasonable processing sequence arrangements may also affect dimensional accuracy due to uneven stress release.
Operational factors
If the operator's technical level is limited, he or she is not proficient in operating the equipment, or there are errors in the measurement process, the mold processing dimensions will not meet the requirements.
Solutions
Equipment maintenance and calibration
Perform regular maintenance on processing equipment and promptly replace worn parts, such as guide rails, screws, etc. At the same time, the equipment is calibrated according to specified cycles to ensure that its accuracy meets processing requirements.
### Tool Management
Establish a tool management system, regularly check tool wear, and replace seriously worn tools in a timely manner. When installing the tool, the operating procedures must be strictly followed to ensure that the installation is correct and firm.
Optimize process
According to the mold material and processing requirements, the cutting amount should be reasonably selected to avoid mold vibration due to excessive cutting force. At the same time, the processing sequence should be optimized and the heat treatment process should be reasonably arranged to reduce the impact of stress on dimensional accuracy.
Improve operational level
Strengthen the training of operators to improve their technical level and operational proficiency. During the measurement process, appropriate measurement tools must be used and the measurement methods must be strictly followed to ensure the accuracy of the measurement results.
