leather

[TwinCam88]

engraving to be specific

anyone attemp it? if so what type of cutter?

[Matthew Hajicek - Singularity]

I've never cut leather on a CNC, but I've done plenty of freehand leather work. Sharpness of tools is critical, and the material is somewhat abrasive. I'd guess a carbide with an edge prep for aluminum aught to work fine.

How about a HSS scribe. HSS will have a sharper edge than carbide, but will dull faster. That's my opinion. Never engraved leather.

laser engraving works great on leather.........sorry no help cutting it or engraving it with a cutter.

I wonder if freezing would help to cut it??? I've done some other strange things over the years that included putting the component in liquid nitrogen after preparing the setup, etc and then cut it real quick before it thaws.

Froze some rubber stoppers once to machine....maybe even freeze the leather piece in a tray of water (slightly submurged)

 

Todd, did you use work in a shop before "goin Mastercam" ?? I often wonder about the backgrounds of you tek folks, know your buddy thats in Europe with Mold Plus had computer engineering? degree. Abbu? He did my installation and I was probably as computer illiterate as they come probably why he left for Europe shortly thereafter

[Todd Tracey from Fastech]

Anbu now owns Moldplus. He was here on a student VISA and they caught him not being a student. I worked for AP Parts in Toledo for 30 years in their engineering center (now FAURECIA) prior to working at FASTech for Bob. We did mostly prototype stamping dies for exhaust systems (mufflers). My wife considers me a GEEK as I have 5 PC's in my office at home and another on the way

I don't think you'd want to submerge your leather in water, that can permanently change it's color and texture, and probably make it shrink. I'd think a vacuum table would work well for holding it. If you're going to be doing a lot of it, you could rig up a liquid Nitrogen squirter to chill the leather around where the tool will be cutting to stiffen it.

[Todd Tracey from Fastech]

It's amazing how the nuts would come out of the woodwork if they heard we had a flask of liquid Nitrogen in the shop just wanting to watch stuff like a hot dog shatter, etc.

I would use a carbide tool with diamond coating. Look at Harvey Tool, they have some good stuff for good prices. Run as fast as your spindle will go and use about .0005 CPT.
