Freeform mold core
Highlight:
• Slow tool servo is adopted
• We accept the expression by the form of XY
polynomials and Zernike polynomials
• The morphology is measured by UA3P
and the corresponding compensation is discussed
Key features:
The PV of freeform mold core is estimated 50% larger
than traditional ASP mold core.
However, the Ra of both types is comparable.
