5 ax flowline help

[Chris Rizzo]

5 ax flowline. 4 axis output along x. Axis control is a cylindrical surface over the part. Will not clean up the yellow areas. Also you can see some heavy length of cut in that area too. Any ideas?

Well it is hard to tell with out seeing the actual toolpath result and the drive geometry, but I'll take a guess and say: try using a Lead or Lag angle (+ or - value) to tilt your tool either towards or away from your flow direction...

 

Can you post some more pictures of how you have the drive geometry setup relative to your WCS/Planes? Also, a screen shot of backplot showing the tool and holder with the toolpath trace turned on will help...

 

Thanks,

[Chris Rizzo]

I'm at home now, and can post more pics tomorrow, but the part is oriented pretty simply. Part is an organic auger shape along x axis. Center of rotation is logical axis of the part. Everything in system top. The second pic you are looking axially down the part, and the z axis is 6-12 o'clock.

 

I've tried all sorts of values for lead/lag and it only gets worse. I've played with just about all the toggles in there and can't get any change. Tool is a .250 ball, tried it with a lollipop and no change either.

 

thanks Colin.

It may be because of the 4 Axis output...

is this a 5 axis machine?

I always have better luck with the Advanced Multiaxis toolpaths. They are extremely powerful.

chris....i used the "morph between two curves" - new toolpaths and got better results. i also had to use LINES to control the motion in that one particular area that you posted a pic of.

Hi Trevor,

 

Check yer mail.

 

man i need a 5ax book.

... or not... Can;t seem to logon...

 

Rizzo... just e-mail it to me if you can and I'll take a look.

[Chris Rizzo]

right at ya!

Lookin' now...

for this part, you will need to switch to the right plane. create a full circle. then in the top plane, create points....probably use the "dynamic" method. once you have the points and circle, break the circle to establish the upper endpoint. draw a line between the point and the geometry at the break point.

 

use that method to establish control lines. if you try to project points, you will get all kinds of different results of line angles.

I'm having cleaner results from the surface I pulled off the solid but still have some issues... looking more at it.
