How to machine a cam with 4 axis ?

[IngParedes]

Hi

 

I´m trying to machine a cam using 4th axis, I hope somebody help me to find an idea, operation or strategy to machine this piece.

I'd turn that then stand it up vertically and profile it.

[Newbeeee™]

It's only small, so (tolerance depending) you could profile the diameter as well as the cam.

Then just flash the back off.

[chris tobey]

(okuma lathe cam cut cams), but if you don't have one -----I would turn complete. Then put in 4th axis and 3d cam if possible on the tolerance

[Watcher]

The walls seems to be perpendicular to the rotation axis. Perhaps C-Axis contour would do it?

 

If you have enough travel on the X axis on the negative side, it could be done even without C axis.

 

What machine?

[duckdogers]

I'd turn that then stand it up vertically and profile it.

I would do it this way also

[crazy^millman]

Flowline 5 Axis, Morph Between 2 Curves, Parallel to curves, Parallel to surface all locked to 4 Axis. You could also do Rotary 4 Axis if you are determined to make it harder on yourself. If you want to do it the easy way you follow what jlw recommend.

Thanks to all for reply

 

Here is my progress, the next steps are the most important, I´ll try flowline and Parallel to surface all locked to 4 Axis (like says "5th Axis Consultin"), If somebody have a diferent idea I'll be grateful.

 

My machine is Haas with 4th axis

The setup and fixtures are like the pictures

Definitely looks easier to machine vertically.

Hi again !

 

Here is the results, I used "Rotary" strategy, was easy to use, I think that this strategy can be use to MacTurn

 

Other ideas and opinions are welcome

 

Thanks to all

why you machining this way ,vertically you can make 10 times faster ???

Because we have only one machine, in this time this machine is working with 4th axis pieces, considering the setup time of the machine with vise and install again the index in this time is faster work with 4 axis.

 

Thanks for your opinion

Since you have a Multus you could have tilted it over on it side it it like a Vertical expect you would have kicked the head over 90 and could have dynamic C axis cut it, or used X and Y axis to mill it. When I get some down time I am going to make up a MT example so show others a different way to go about a part like this.

[jlw™]

Man, you have a multus and had to ask about this part?

apologies:

before it was clear he was talking about a mill i threw in a comment about turning the shape on a Macturn. after realizing my comment wasn't needed/ maybe a hijack for the question asked i remove it.

 so now you can blame me for the confusion.

You should be running parallel to the z-axis.

Yes many people have never done Mill/Turn and the processing of parts and the methods take time to get your brain wrapped around.

I think people are getting confused. The machine is a Haas not a Macturn. 

 

IngParedes, I understand not wanting to tear down the setup just for one part. You are on the right path, the rotary path will be a good one for what you are trying to do. If you haven't got this figured out yet feel free to post up a file and I will give you a hand with it.

You are doing this the wrong way. You can cut this parallel in the Z-axis (aka Side mill/face mill) and use a dynamic path to rough it out, and a simple contour to finish. Faster and easier on the tools and the machine.

Can we get past that already? Did you not read the part that he said he doesn't want to tear down a frequently used setup just for this one part? It's time to move on.

No. He is doing it wrong. Making life more difficult. Can't move on until doing it right.

[David Colin]

If he needs to do it that way, it is his business...

 

I did a fast example that could be a pre-finishing with morph between 2 surfaces toolpath (if you have multiaxis add-on and your post is ok).

Same toolpath can be use for finishing with simple tweaks.

Ever done any turning on a mill?

[BenK]

That is a truly ignorant statement. You are obviously a person that can't think outside your comfort zone. Their are many ways to accomplish any given task in this trade, and the fact that I need to point that out to you speaks volumes. He is doing it in a way that requires less overall work on his part by reducing setup time, just a little more run time and programming effort. Overall what he is trying to do is a very simple multi-axis programming example that will teach him something new. Regardless of what your opinion is on his methods, to say he is doing it wrong is simply incorrect. If you have nothing constructive to add to a conversation you should just keep quiet. Who knows, you may learn something.
