Hello, this is my first post and I was hoping to get some advice engraving raised stamps.
I have cut a few raised stamps already using a 3/16 dia. x 60° engraving bit to achieve a raised island of the letters/numbers/symbols desired to stamp onto the material and so far they have come out looking fairly good. However, it seems like there is material left at the bottom of the island where the stamp meets the block.
Am I having a tool height issue or maybe a tool wear issue? Both?
I have been running the machine at 10k rpm (fastest possible) @ 20ipm with approx. .002 DoC and .002 stepover.
Does anyone have any experience cutting stamps like these? I would really appreciate any advice!
Thanks!!
