Engraving

[Leandro]

¿Is the engraving ADD-on 5 axis Capable?

[cadcam]

No, are you just trying to engrave letters or you want to do the 3D cornering like the engraving package does with 2D?

 

I am trying to find out what you want to do to see if I can help more.

[Leandro]

That what I need to engrave is like this picture.

This a Tire Mould.

This must be engraved in 5 axis

Im am looking for the easiest way.

 

Thanks

that is a cool xxxx mould. someone should start a new area of the fourum for projects

I would agree Robert. Look at the detail. Very well done Leandro.

engrave is mostly for that chisled cut wood sign like cutting. It rides a tapered tool up and out of the corners of letters/shapes to get that sharp cornered look.

 

Your Pirelli looks more like Multisurf 5 Axis contained to the letter shape.

wow that's neat. looks like a lo-pro pirelli. I can't imagine the quantity of molds you must have for the variety of sizes. what's the material (for the molds)?

 

sorry more questions than answers.

You can do 4 and 5 axis machining with the Engrave Toolpath.

 

You have to go to the "Wrapping" option and choose between using "Two Curves" or "On Surfaces".

Thanks Mark I had forgotten about the "wrapping" option. I am wrong on my earlier statement sorry.

Hey Leandro,

 

Do you happen to have any pics of the other components of the mold ? I imagine it has to be segmented to release the tread areas... That would be cool to see.

Thanks Guys.

Chris, yes there are a lot of sizes, brands and different marks.

Material is usual SAE 1020. Rubber is not like plastic. Ther is usual to weld some parts and engrave again (e.g. plies Polyester,steel,nylon etc)

A lot of tread pattern are of aluminum (a lot casted but also engraved). Now the tendence in bigger molds is to engraved steel. But this molds are very expensive

Matt I have got a lot of pictures if you want just send me an email I will send you ([email protected])

 

Now to my question.

Today for engrave this I do all this procedure.

 

I create a surface with the caviti profile.

I create an offset from the outer boundary from the letter. (0,5 x Tool radius)

I trim-surface the surface to get a surface from the letter.

Now I machine with a 5ax- Flowline and later a 5ax-Curve for get better boundaries of my machined letters

 

A lot of steps.

 

Mark could be engraving Add-on a solution to aboid all this steps ??

Supports engraving 5-axis??

 

Did somebody have any example about this kind of engraving. Or how works engraving

 

Thanks

Ola Leandro,

 

Here in Brazil, we have some tire mold maker customers. They are doing lettering sometimes with simple 3d contours with conic tools, no compensation, and sometimes using the engrave operation within the advanced multi-axis. Some are doing the 'cavities' using the profiles as a boundary to contain the toolpath.

Leando, the way 5x engrave works is that you have you're geometry in the flat and either select two drive curves (the shape of the surface) or select a surface. It works pretty well, getting the toolpath to start in the correct spot might take a try or two (as I recall). Its been a while since I've cut a 5x Engrave toolpath.

 

I don't check the forum on a regular basis so if you have a question for me, send me an e-mail.
