Reverse Countersink in Blind Slot

[MFZTM6E]

Im new to Fusion and Im struggling to programme a reverse countersink in to a blind 'keyhole' slot.

i want to feed the cutter in at the large end of the key, move along and create the countersink by raising the cutter, then drop down and move back to large end to exit slot.

Help would be nice please

Can you share a sample file that has this feature?

I suspect it's going to be challenging to program. We might be able to accomplish this with the Trace toolpath, but that's only a guess...

If you mean an underside chamfer (countersink implies its a round feature) then Trace is the only way. Been there!

[MFZTM6E]

the feature highlighted as under the key slot is a round countersink, the slot is a blind slot.

got a feeling im going to have to manually prog it?

Simply sketch this on the midplane of your feature, then use a Pattern function to repeat it.
