Part Marking Height

[Newty]

I have a small part that I need to mark with an ID number. I'd like for the marking to similiar to indelible black ink.

Can someone provide help with these questions?
1. What is the smallest height that can generally be done for this. Is .0625" to small?
2. Any suggestions for the note that will indicate what type of marking should be used? I have "Mark part in approximate location" but would like to specify the process to be used.

Thanks.

If you don't have an in house process for marking, you could use a mil std such as MIL-STD-130, or you could just specify what you will accept in a flag note.

Something like.

INDELIBLY MARK WITH PART NUMBER IN LOCATION SHOWN. MARKING SHALL BE XXXX FONT .06 HIGH CHARACTERS.

If you dont' care what font you could use some other wording so long as it's clear you want 'type' font not hand written.

In castings they'll call up 'RUBBER STAMP' for this type of thing I believe.

.06 (don't bother with .0025 - it's marking not precision machining) is on the small side, you may want to check with your vendor.

Videojet produces machines that can do this type of marking. Here is one example that can print as small as 0.8 mm (0.03 inches):

I forgot to say, you may want to specify color/colour too.
