I have a client that wants me to deep engrave their logo, which is basic text and about .125 tall. They want me to go .010" into titanium.
I didnt have any scrap laying around so i used aluminum which i read had simular properties when it comes to lasering.
The aluminum came out very nice, with straight edges and a flat bottom. When I lasered the titanium with the same parameters just more cycles to get the depth i needed, the bottom on the text looked like it was a 5th grader welding or. I sent the part to the customer and they did not approve. They are looking for a clean bottom.
My laser is a 30W chinese BM laser with EZCAD.
Parameters are:
Fill 1: 90 hatch, .05mm spacing, 35 loops, 100 power,500 mm/s,35 freq
Fill 2: 180 hatch, Same settings as above
The total cycle time was 10min per side. Had to do both sides of the part.
Anyone else ever done this or have any ideas on what to do?
