hyperboloid parabolic

[HEAVY METAL]

hyperboloid parabolic   any one done one before  or familiar with it 

 

Thanks  

[Greg Williams]

Sounds impressive, do you want to draw one or machine it?

[crazy^millman]

What is the formula you have been given to make the shape? A parametric modeler would be best since you can define your mathematical expressions in it to get your shape. 

Here is some light reading about the shapes:

Paraboloid

Hyperbolid

I've done a few of these.

In my case it was with a customer supplied model, or customer supplied point tables

that were used to create the defining splines.

Solidworks can make equation driven curves for modelling.  Then I'd just bring it into Mastercam and treat it like any other model.

Or you could use this program called .... Mastercam and a c-hook Fplot ( Function plot )

Thanks guys

Yes unfortunately I have to create the model .  I don't have soildworks so I willl take a look at the c-hook

I don't know how long you have been using Mastercam Gracjan but your Mastercam knowledge is vast to say the least. its impressive, keep up the good work buddy.

Yeah, the Function Plot C-Hook can be used to plot out all kinds of curves, to a given tolerance. The only issue is the "input" has to be in equation form. What kind of data were you given?

I've seen some pretty unusual applications for creating geometry in Mastercam. For mechanical Cams, John Summers built some specialized Posts in V9, in order to be able to 'pass' input data to the Post, and the Post output would be a set of XY points that lie along the Cam profile.

Trying to upload a picture of the part .  I keep getting a error that file size  is to big . How can I get around this ?

[Colin Gilchrist]

You could open the file in Microsoft Paint, and try saving it out as a ".PNG". The Portable Network Graphic seems to be a pretty "lightweight" format...

 How  can I delete my uploaded files to clear space

 

[HEAVY METAL]

I don't see the function plot c-hook . Is it one you have to download ?

Click on your "profile name" in the upper right corner. Go to "My attachments". Delete as necessary.

F-Plot has been installed with Mastercam since I first started using it. It is possible that you might have to download this from the official Mastercam Forum, but I wouldn't know until after I get off work. (I use NX at work to program with...)

I checked from X6 to 2018 and it is in every release I have in the chooks folder. fplot.dll

 

 

fplot.dll

When you launch the C-Hook, just open Mastercam, and with your cursor inside the Graphics Window, press ALT + C on the keyboard to launch a C-Hook function. You should be inside the "chooks" folder from your Mastercam install. (When you launch the C-Hook function, Mastercam will open a browse window, to that location.)

I don't think print has enough enough info  .   I did find the fplot c-hook   

rollers should form straight line in 35 deg -----additional note

I don't see .EQN for a hyperboloid in the fplot c-hook

 

[Colin Gilchrist]

I'm really not sure how to interpret the "straight at 35 degrees" note, but perhaps this PDF might help you? At least it lists each of the equations you might need to do the construction...

[Colin Gilchrist]

Honestly dude, looking at that data, I can't see how anyone would be able to "tell" what that shape was supposed to be? How are they going to measure that "Hyperbolic Parabola"?

I think that is just a load of crap, from someone who didn't understand how to properly describe the shape they want you to create.

I would draw out the intersection points (They give you the lowest diameter as 85.5mm), and construct a 3 point arc that connects the endpoints of the 33.5mm line, and bottom point.

How are they going to inspect it? Do they have a template? Or would they just be taking a series of XZ Points, along the Contour?

The method I used to make that would depend entirely on how they plan to inspect this mythical Hyperbolic Parabola.

Thanks Colin for the PDF . I took a look at the c-hook not sure what one use.  would it be  ellipsd.eqn  ?

[Colin Gilchrist]

It's been 10 years since I messed with fplot. I'll have to look tonight and get back to you on that. I seem to remember being able to just type in an equation. It was only for the more complex equations that a .eqn file was needed. But again, it's been 10 years.

Maybe one of the guys from CNC Software would know?

Paging... Roger Martin!

Thats my list of options under the F-plot
