cam per torniture

[Bellabella Manciù]

are new in the field of turning, the company wants to invest on the purchase of a specific cam for fixed fan turns with motorized and y axis (biglia with siemens control). the reason for this investment is to reduce the programming times of new samples.

made this premise I wanted the following tips:
- is it true that programming times are reduced? ?
- what parameters should I take into account when buying a turning cam, considering my deep ignorance in the matter, as I do not even know if it is essential to draw the piece with surfaces or not.
- to large lines is assimilar to the purchase of a milling cam? ? ?

Thank you all in advance. Hello lucia

made this premise I wanted the following tips:
- is it true that programming times are reduced? ? I would say yes, after the apprenticeship- what parameters should I take into account when buying a turning cam, considering my deep ignorance in the matter, as I do not even know if it is essential to draw the piece with surfaces or not.
it is useful if they give you or you have the 3d file (solid ) or in cad 2d format but in this case you will have problems in checking the collisions , if you have to redesign the piece is better if you also have a cad i cam have a design module but it is usually Moroccan- to large lines is assimilar to the purchase of a milling cam? ? ?
I would say that you must be careful about the posts, fix the development timing because if there is no realisation it takes time and effort both yours and the programmerThank you all in advance. Hello lucia

This is what I saw in my company, but there will be others who can advise you better

Hi.

 

[PopeYe]

in turning the purchase of a cad-cam is very beneficial if the piece is of considerable difficulty or is of considerable value (as in milling the rest).
In the first case you will have an advantage in the programming time avoiding unnecessary calculations and any recalculations in the case of machine optimizations, in the second case the probability of discarding the piece or of having to repair it is very remote therefore even if the programming time turns out + high you would still have an advantage.
with the latest cncs, see siemens, programming has become very + simple (you can even import dwg files) therefore the cam very often is only an extra tool that should be used where you denote convenience.
but here comes into play the individual and corporate experience.
to properly evaluate everything tries to advise you with the programmers and operators you have in the company, they will surely better identify the problems that you create in production, and if the cam could solve them.
if you have to test one, test it on a real piece that you have to perform, if the demo want to make it on their file (as usual) don't even start them since you will need it shortly.
an experienced programmer will surely tell you whether the paths are reasoned or not.

:finger:. more than just! In fact it depends very much on the details that will be realized. in company we have a mazak lathe with ut. motorized and axis y: number programs made with the cam=0 (zero)!!!! programming on board machine with the mazatrol is very fast. I think that also the siemens control for turning (with shopturn) is quite intuitive (I use it in milling with shopmill).
if then the need is to reduce the programming time of sampling consider that:
- not always the first piece will be right
- the programme must be amended
- small changes to the program the language iso you can make on the machine
- big changes you're gonna have to go back to the pc and work with the cam.

hi and good work

I subscribe to what the colleagues said.
However, I still break a lance in favour of the cam also for medium-low complex work and essentially for 2 reasons:

1) programming on board machine, even if in masked time (while the machine turns) is never maximum efficiency: too many "distractions" of the type
"wait... What's the noise??" or "azz... He's already finished the piece, now I'm gonna have to do the other place.

2) in the presence of machines equivalent as typology, but with different cncs, especially if they do not work in flat iso, the cam allows to pass the program from one control to another simply reprocessing the partprogram with the postprocessor that serves for the machine to use.
the advantage is evident not only in terms of time and flexibility "the lathe with the fanuc is busy/stop? ok, we pass the piece to the other machine with the siemens" but also and especially at the program update level.
or, if I have 2 or more machine programs for a single piece to work on different machines, any modification on the original partprogram will automatically transfer to machine programs, simply reprocessing them.

I agree with the fact that on board the machine you can make quick changes, but not too invasive, also to the programs made on the cam.
the perfect cam, which program exactly as we would like, still does not exist and all, who more than anyone, tend to "extend the broth" of the machine code.
so a fast tuning of the code is not only allowed, but also necessary.
always, of course, strictly documenting such variations, so that you can repeat them in case of further modification of the program or even accidental deletion of the same.

Thank you so much for the precious advice you have given me so far.
I take advantage to ask for further explanations:
1)from what I understand the post I get out a program in lingaggio iso point (as for milling) or a more complex language (with codes g)?
if it were point point according to my experience you quickly pass to remarkable file sizes while my cn has 256kb (redirecto non siemens but fanuc 18 i tb). How do you solve this problem?
2)the library tools that I will create inside the cam will have to contain only the design of the tool or of all the lock/motorized (porter, or wreath or special). I wonder why I'm afraid of collisions where many elements work closely: Spindle countermandrino turrets and piece.

Hello lucia

 

[Meccbell]

1) what you ask depends on the ability or not of a postprocessor to generate files that contain the typical functions of each single control, such as special fixed cycles not iso, macros, use of variables, etc.
obvious that if this happens the code that comes out is much more compact and efficient than the same program generated using only g0-g1-g2-g3 (with these 4 functions it is possible, theoretically, to perform any processing of profiles, even of the most complex ones, obviously paying the rock of kilometric programs also for a simple roughing and contouring).

2) the simulation of which you speak is certainly possible if you opt for a three-dimensional engine cam that allows the construction (directly or externally) of all the solids constituting the spindle, the tools and even the whole machine.
Of course, if the cam provider doesn't have bookcases already ready, one of the first works to do will be to "build" the machine to simulate.

about the problem of collision verification, here you could open a discussion among those who support the need to use programs outside the cam (Vericut type) and those who are fine with the native function of the cam.
It's an old dispute where everyone is right or wrong.
if opting for one or the other solution depends on many factors; First of all if the chosen cam or in use this thing does it or not.

normally comes out an iso with g codes but you can also use cn macros, of course the first is normally + reliable if it were point point according to my experience you quickly pass to remarkable file sizes while my cn has 256kb (redirecto non siemens but fanuc 18 i tb). How do you solve this problem?
quietly with a card, usb or hard disk (depends what kind of device has the cn) because with the fanuc 18 you can also call a progr. on external peripheral to the cn, however I don't think that to that quantity you will arrive easily2)the library tools that I will create inside the cam will have to contain only the design of the tool or of all the lock/motorized (porter, or wreath or special). I wonder why I'm afraid of collisions where many elements work closely: Spindle countermandrino turrets and piece.
the most defined libraries are better for collision control, especially for machines with + heads and + axes. if you can better use a program that reads the file after it is processed, because it is by far + safe, besides some verification programs interface directly with the cam and can also read specific languages for the various cn

ciao lucia

let us know what sw will fall your choice ...

 

[Bellabella Manciù]

I'm planning to go to the emo in Milan so I see to make a first scrambling of the possible choices.

are oriented towards top solid, delcam (partmaker), hypermill, edgecam and mastercam. I will also make custom demos.... I keep you informed about the final choice. if you have any other valid candidates are open to any advice.

Thank you for everything

I would add esprit as you want to see them all

Hi.

 

[PopeYe]

in the topsolid stand you will also find goelan that in turning is not to be underestimated (also interesting innovative graphics).
among those mentioned, topsolid is the only integrated 3d cad-cam, totally parametric, with machine cinematics in the same environment.
which is not recently... especially if you can use a parametric cad.

 

[Bellabella Manciù]

We are back from the emo and I must say that the cam that surprised me more is esprit cam you know how to judge me, because in my opinion it has the best value for money.

Thank you for everything
