Help With Toolpath Selection

[Justin Beebe at Folsom Tool]

This is my first time making a part like this and I need help selecting what toolpaths to use. I will be running this part on a Fadal-5-axis vertical mill. The thickness and the diameter will already be turned to size and the middle hole will be to size when the parts comes to me. I plan on locating the part and holding it down with the middle hole. I do not know how to mill the three cutouts and the chamfer that cuts into the OD. Any help is appreciated. Here is a picture of the part. I can supply more pics if needed.

The Curve 5X toolpath using axis control lines, would be my first try. For both milling out the tabs and doing the chamfers. You may have to get a special angled tool for chamfering. The biggest issue would be the fillets or lack of.

To cut the od try 3d contour this will leave

radii in the corners - for the chanfers

try swarf to finish the corners maybe

surface contours with lines for toolaxis control

some geometry needs to be created for this

I can e-mail you an example if you want

We just bought a used 5 axis makino I would like to see that 5 axis example if you don't mind. 5 axis programming is new to me so the more examples I can find the better .

Thanks Heavy

Justin, throw the part on the ftp site so we can give you some suggestions.

Thanks for the replies. I can't put the file on the FTP. I would like to see the sample part. Can you put that on the FTP site. If not I can give you my email. I just don't want to post it for all the world to see.

[JDowe]

Could not get FTP to take the file

will e-mail a sample if you want

jdowe could you send it to [email protected]

 

thanks

Looks like a good wire edm job

This Looks like a fairly easy job for Multiaxis/swarf 5 axis use these settings

Output format: 5 Axis

Walls: use Chains - select lower, and upper chains

Tipcomp: Lower rail with a - distance number.

 

This toolpath will work great for the sides, and the chamfer, the only problem will be to get the square corners. if your machine has a c-axis in the table, you may have to raise the part enough to tilt the head and use a curve 5ax toolpath to clean the corners

The 3d contour I am thinking about just controls the tip of the tool, it dosn't tilt the head to cut a draft angle. Is there another 3d contour that will allow you to cut a draft angle? I had to look at the pic from my iPhone, because it is blocked at work, so maybe I am looking at it wrong.

Thanks for all the info. This job was pushed back a little bit. When I start to program it I'll try all these suggestions and let you guys know what works.

 

Thanks again

If you send the file to my e-mail I can put the toolpath on it for you. If you don't want to share it, I can create a similar solid with toolpath, so you can see how the toolpath works.

Mcam Nut,

 

I may be able to create surfaces or wireframe for the geometry that needs to be machined and send you only the surfaces and wireframe. I will have to look into that. I have a few hot jobs to knock out first. I'll get in touch with you when I start to work on this job. I really appreciate all the help I'm getting from everyone.
