The crank arm is swaged to the ring, and that makes applying significant force to either use a hammer (to beat out the pin), or a spanner (to get the cup off) an operation that could result in significant lacerations.
If it won't ride off, I think I'll have to puzzle out the removal of the BB as a preliminary step.
Use a large drift (4-6") held over the pin with a pair of vise-grips. No danger to anything but the chainring, if you miss.
FYI, an engineer's hammer has a knurled face, to reduce slipping when it hits a metal forming tool.
