4th Axis Help Please

[Newbeeee™]

Hi All,

Newbeeee by name and by nature...

 

I've uploaded a file to the ftp called NewbeeeeHelp.mcx in the X4 folder.

Please can someone have a look and advise the best way to cut the form?

It's a VMC with a full 4th, and the file is (hopefully) set-up correctly but I cannot get it to work.

We have Curve 5ax but no luck there...

Many thanks in anticipation.

I would look at roll-die since it is a cam type of part. You could make curve 5 axis with point as the axis control through the center of the rotation.

It will run 4 axis 3d contour if the spline is

broken into segments - part of the smaller

spline is undercut from the larger spline

and the walls are not perpendicular to the

axis of rotation so the part would not be

as drawn - maybe a 5 axis part?

Many thanks for the pointers guys, I'll have a look when I'm back at work in the morning.

BTW, the part shouldn't be undercut - it's badly modelled.

Cheers

Also ran it by creating new splines on the

upper and lower edge of the vertical surface

and created a multiaxis swarf toolpath

limited to 4th axis - needed new splines because

the endpoints on the originals do not match

JD,

Please can you save that back to the FTP so I can look at it in the morning?

There's nothing like a practical example!

 

BTW, ref your earlier comment - how do you break the spline into segments and what size did you do to make it run?

Many thanks again.

Ron,

Rolldie worked but not as configurable as 5ax.

No multicut/leadin-out etc.

 

Curve 5ax looks good with point at centre as you suggested. Having never 'played' with this path before I needed pointing in the right direction.

So thanks for that.
