What are the ways to ensure and improve machining accuracy?
1. Error prevention technology: Reasonable use of advanced technology and equipment to directly reduce the original error, transfer the original error and equalize the original error.
2. Error compensation technology: On-line detection of automatic matching and grinding of paired parts actively controls the error factors that play a decisive role.
What does the machined surface geometry include?
Geometric phase roughness, surface waviness, grain orientation, surface defects
13. What are the physical and chemical properties of the surface layer material?
1. Cold work hardening of surface metal
2. Metallographic deformation of surface layer metal
3. Residual stress of surface metal
