Tearing of castings during machining

Tear-like damage appears when cast products are cut or drilled. This problem is relatively common in casting molding production and requires comprehensive analysis and solution from multiple aspects of material, process, and equipment.

(1) Process factor: Over-curing makes the material brittle, This factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: Or insufficient curing leads to insufficient strength, This factor affects the '2079851475616104453 and final quality of the product. (3) Material aspect: Fluctuations in raw material performance indicators or insufficient pretreatment affect molding quality. (4) Process aspect: Control deviation of key process parameters causes the '2079851475616104453 to deviate from optimal conditions. (5) Equipment aspect: Equipment precision and maintenance status affect the stable execution of process parameters.

(1) Process control: Control the curing degree within the optimal machining range, Establish an online monitoring mechanism, set upper and lower parameter limits, and implement alarm management. (2) Material selection: Use sharp tools and appropriate feed rates, Establish material selection evaluation criteria, and determine the optimal solution through comparative tests. (3) Implementation measure: Heat before machining if necessary., Develop a specific operation plan based on actual production conditions, and verify the implementation effect. (4) Preventive measure: Establish sound process control standards and a quality inspection system, and regularly review process data for continuous optimization.

This problem requires comprehensive analysis from multiple dimensions of material, process, equipment, and operation, and should be solved by systematically optimizing process parameters and the quality control system.
