cam high band all good???

[TECNOMODEL]

every software house should have technical facilities that create a personalized post according to your machine and your needs. also this is an aspect to be evaluated for purchase.

 

[LaboratorioDieci]

thanks for the clarification... So what do you recommend?? or at least what upsets me[emoji3][emoji3]

As always... It depends! If you actually find yourself fresare maquette per l'automotive or similar, I think you should rate nx. if you work a lot in the artifice maybe among the candidates you should put hyper milligrams. in any case I do not feel that I do not recommend anything you have indicated previously.

I can tell you to carefully evaluate the professionalism of the technicians who will have to prepare the posts. I use a high-level cam, but the official Italian dealer is very unprepared about the type of machines I use (of course I can't make names); for errors in the posts I risked more than once to knock down the machines. in the simulation phase on the cam you see everything perfect but then if the post has gaps/errors, the translation in machine language can reserve unpleasant surprises. . .

absolutely true. If I can break a spear in favor of those who write post processors, I must say that sometimes it is not easy to find the necessary information at the manufacturers of controls. when I had to do it for a siemens control I had great difficulties. and comparing me with other technicians we shared the feeling that siemens does not do it without mischief.. .

for what on machines of a certain type would be better to equip itself also of a simulator of paths.

This also depends.
if the simulator comes from the same manufacturer of the machine then it is a safety source, otherwise it requires the implementation of the machine, which at the end of the fair is a post processor to the reverse, with all the doubts of the case.
then depends also on the context in which you work: if in the company you use only one cam, then the simulator can be useful only at the stage when you develop the post processor (always if the virtual simulator machine is reliable!).
if in the company you use more cam already is a little (but little) more useful.
the simulator becomes important if in the company they send in processing the iso (yes, I know, you would not say so but we do to understand) provided by third parties.

 

[vmirko]

verifying the path before sending it to the car is an extra safety, you just have to check out a gap and are pains.
on a 5 axes with a collision you pay the simulator.

 

[Stefano_GS]

also because in the simulator you can insert every element that you physically have in the machine including all the fixing systems and everything you can have in the car.

on particularly expensive details, even worked on 3 axes machines of not particularly high range, is the practice to simulate each individual path and every single variation.

in a well-known aerospace company the variation of a working cycle that provided:
- drilling one step
- boring

for example
- multi step drilling
- boring

is reimposed. this to establish a practice that always applies, even for minor changes.

hi to everyone, we only work with a cam (when we decide which ? ) and only with a car , we look for a complete cam of post and simulator collisions of the whole machine , not to harm .. we make unique pieces, and you would like to fill the machine plan of different objects , prepare the tool path and start the whole thing

 

[vmirko]

of simulators I know of fame are eureka and veracut.

 

[ale47p]

if you do everything from software, including tool change etc., the simulator does not need.
you just need what is usually included in the software (powermill is provided).

we use veracut because between scale factors, shifts origin, specularity and various magasins you cannot simulate everything in powermill, because in fact, the post-processed programs are then manipulated by the master of the machine (in addition to the fact that a post we do not support the sixth axis, which we have on a tool machine).

our case is quite limited, but we mill molds and models of stuff from the most extravagant geometries. ..a few geometric pieces

I repeat, if you do everything inside the software, giving the machine only and exclusively a unique post-processed program, the simulator does not serve.

the immense advantage of the simulator is, that, after setting the simulator for good and tested for all eventualities, it no longer misses even a piece (except the problems connected purely to the machine tool), so sleep much quieter and you have much less surprises.

the disadvantage of the simulator is, that once you start using it, you will no longer do without it

Good evening
I ask a question not inherent to the thread, but I do it only in order to avoid the proliferation of useless or uninteresting topic.

I come to the question. I am ani who insist with my friends, saying that the section phi 20 does not exist; exists phi 20 h7; it may exist phi 20 j5 but a section without its tolerance is incomplete and useless.
When I ask how they would plan a cnc by also putting the information of tolerance, no one can answer me. they would put all absolute (or relative) coordination but without giving tolerance, doing everything to the machine and taking good the artifact without checking.

then the question is: how do you plan a trajectory if I want a section with assigned tolerance'
Thank you.

 

[LaboratorioDieci]

Thank you.

a dimension with tolerance should be programmed as the average between the minimum and maximum limits of the permissible size. if then the tolerance is particularly tight it would be to handle with the active tool radius compensation.

 

[ale47p]

creating a new discussion was better, iho, maybe passing a moderator to divide them

on a "new" processing pulls out the micrometer, it controls and adjusts.

for all the rest sell h7 tips, alestors, adjustable barns... and measuring instruments

 

[bulinorotto]

Why don't you consider siemens nx?

 

[jakysmilzo]

finished research ... we bought esprit .. especially for the availability of the seller and its technicians ...of course also the product has convinced us and meets us ..thanks to all for the advice?

 

[bulinorotto]

the finishing does not make you the cam but the machine and the tools.
you can also have tebis, for example, but if you have a center with a "old" control and little speed on the spindle a good finish you forget.

I do not agree, the finishing depends not only on the machine, but on the cam, the tooling, the extensions/mandrinos, the handling, the numerical control and the machine.

of what you said the cam has the least influence.
I had proof just before the holidays, working on a new dmg a matrix that we had already worked in the past on an old c.b.ferrari.
a small problem of irregularities in a restricted area that had never been highlighted in the past, analyzing up the file we saw that in that area the geometry of the footprint had an area opened by a few cents and a discontinuity on the surfaces.
same cad, same cam, same tools and spindles, different machine.

If you rely on a certain level you begin to see the differences of the machines, but trust me with esprit my 1999 cnc has already made giant steps in comparison with the previous cam

I imagine that you have not seen any difference if you have not changed anything in the cam! , according to machine tool and control the cam must dialogue differently (type of post, machine dynamic management, different tolerances, decimals after different comma etc.)
