roughing

[Il marangon]

Hello

I have to make a roughing of an aluminum plate but the cutter I would like to use can not enter the ramp but only externally, it is possible to exclude the routes that would enter the ramp or force the outside entrance to the block?

Hello Marangon,
then if I understood the question you did, you would like to create with powermill a roughing path that does not have a ramp approach with the rough to work, if so, it is enough that you use as a roughing strategy "sgrossing offset" or "grimming with past parallels". in both strategies, there is a "movements towards the inside" and a curtain where you have to select "on the model", then pin if it is the "outdoor entry", then select in the curtain of the "junctions" pane the "no" item. If you still don't like the resulting path, you have to go to the "swimmings and joints" every time you calculate the roughing. . .

If I wanted to work this piece with a cutter to inserts whose centerpiece does not cut, I would be able to work all the piece except the quarry at the top of the pyramid. the rest of the route should by force start externally to the block.

How do you exclude those paths that would enter the full of the material or ramp?

So, if I get it right, you don't want to work your pocket during the roughing! you could do in 2 very simple ways:
1) you can create a boundary for grinding and tell the path to enter or not in the pocket;
2) you can create a cap surface on your pocket and do not need to create so no boundary because the perchro during the calculation would feel the surface and would pass on ignoring the pocket.
Once the piece has been cut, you can do a hole in the middle of it, from which you can go in with a frieze and make us rough before finishing it!

ok, for this piece is also feasible but now I'm working a mold so the solutions you proposed are not feasible.

I have a pocket that half can work with external entrances and not for the other part.

I wanted to understand if there was a possibility to exclude all those areas that by force of things had to have a ramp entry without intervening with closing caps or boundery

We are in the magenta area, we are a new company and we need a tool that follows us for the new projects. . .

hi marangon, sincerely I never had a problem similar to yours, so I never put it, but I don't think that powermill (at least until my version, 7.0) allows you to choose a different approach between the calculated paths of the same processing strategy; I don't know, if you did, I'd beg you to tell me how you did it!!!! Hey!

If I understand your problem well I usually adopt 2 systems.
the first is to delete the part of paths that I do not want to run from the table " list of past of the tool path"; but if then I recalculate for some
That's why the route recreates them and I still have to cancel them.
the second imposed the z step from automatic to manual, after making the calculation first time, and gate the heights that I do not want to achieve. this if you have to recalculate the path is definitive.
logically deleting a height z this is relative to the whole path and not to a
particular area.
another solution could be to select the surface of the bottom of the pocket, and in the table "overmetal preferences" the amounts and gives it an axial overmetal,
for example of 20mm, if this measure corresponds to the portion of pocket where you do not want
let the tool in.
test ;
I hope I've helped you, bye

have you tried with the area filter? ? ?

Hi.
to work that piece
it takes two routes
one who only makes his pocket
1)a series of holes
roughing
semifinishing and finishing
then you do the rest
If the question only concerns whether the sw does certain things is another prob
if this prob does not solve it with the sw
It's not like
Thank you very much
