Analysis of processing objects
Processing materials: Ceramic matrix composites (CMC)
Core features: Planar milling processing requirements
Material properties: Density is only 2.3g/cm³, thermal expansion coefficient is lower than 4.5×10-6/℃, and it has both super wear resistance and insulation performance, making it an ideal choice for new aircraft structural parts.
Industry pain points and challenges
With the development of lightweight aviation equipment, a certain aerospace research institute encountered a difficult processing problem when manufacturing a certain type of verification aircraft load-bearing frame:
Material sensitivity: cutting fluid is prohibited to prevent surface contamination from causing structural failure
Traditional dry cutting defects: the average tool life is only 25 minutes, and the burr height of the processing surface is 0.12mm
Low processing efficiency: the single-piece working time exceeds 8 hours, which cannot meet the project node requirements
MID solutions innovation plan
In response to the special needs of the aviation field, the MID R&D team launched a combined processing solution:
Multi-purpose ultrasonic green engraving and milling system: achieve micron-level processing accuracy
Low-temperature supercritical CO2 technology (-78℃): replace traditional cooling methods to avoid material contamination
Adaptive ultrasonic amplitude control: dynamically adjust cutting parameters according to material hardness
Comparison of actual measured results
A breakthrough has been made in the processing of the verification aircraft load-bearing frame:
1. Surface roughness increased from Ra1.6 to Ra0.4
2.Single-piece processing time shortened to 3.2 hours
3.Tool life extended to 76 minutes
4.The peak cutting force is reduced by 43%, and the incidence of material micro-cracks is reduced to zero.
