machining text???

Come out awesome for me.

I re-did the toolpath using a small c.drill.

 

 

IMO,using 2d chamfer and that chamfer mill is not the right aproach.

Edit:

I got rid of the phone # in pic,wasn't sure if it was cool to post it.

Franck,

 

I looked at your file on the FTP site.

Do NOT use 2D Chamfer. Even though compensation is turned off, this toolpath is compensated.

 

To outline your letters:

I changed it to 2D and used a taper Mill with .0001 tip (instead of chamfer Mill) and it worked great.

 

To fill-in your letters:

You can also use the pocket toolpath with parallel spiral (inside to outside) with .002 step over. This worked great too.

Frank,

 

"parce que le jour j'ai un autre emploi"

 

Making a little on the side eh? Good going.

 

If you look at what Brendan did up above you will see that visually some letters could use some shifting. For example the "a" in Fralex could be shifted to the left a bit as well as the "ex" also in fralex. This is common, due to where the control point is set for each letter. Some letters just dont look too good side be side.

 

I am saying this just so you are aware of the issue. I would sugest you take the time to xform the letters to make the engraving appealing to your eye.

when I will do it with my 1/16 ball nose, will it do the job nice or it will exceed the limit of the letter.

 

Btw phone number was posted on an another post and this part is to give to customer, it's key chain (not sure for the term in english)

 

thanks all for the patient and for the time spent on this i'll check that tonight

[Fralex_francois]

Thanks Phil for the advice I saw it when I generated them but forgot to x form them...

BTW yeah it's on the side but growing to be the main job (finger cross)

 

...you speak french in Vancouver???

Frank,

 

I was born and raised in Magog. I have my three kids in french emersion at school.

 

Also for crisper lettering we use 30 deg carbide engraving tools so we can get into tight corners with the engraving. Using small center drills work well too.

Do they have to be in carbide or if my part is in alum. HSS is ok???

 

content de savoir que du monde continue de parler francais meme dans un milieu anglophone.

Just want to tell you guys that I made the first try on the machine... and it works great

 

I've done it with pocket with taper end mill .001

and I machined it with no1 center drill wich made quite a good job

 

Gonna start doing production of this project to give to my customer!!

 

Thanks again every one!!!

Eh, doucement! C'est moi!

 

I was too late to chime in on the lettering problem, but wanted to demonstrate that I took French in Junior High School. Obviously, I didn't learn much, 'cuz that's all I remember.

A #1 center Drill. .006 deep will give nice look

some material you have to make a free pass to

clean it up.

Franck, would you believe we acutally were taught that in class? It was in our text book!

[Philcott]

Mark,

 

It must have been the same book JFK (the real one) learned his german from.
