4.5 axis toolpath in ver 9.1MR0304

[ERIC14779]

I have a simular problem to

 

"Terry5357 need advanced multi axis help please"

 

I was tring to help him and little did I know I would be in the same boat today !!!!

 

I have a presure vessel end mold that I am tring to program for. It is 18.25" in dia. and 12" tall.

 

I am going to cut it out of renshape and vacuumform over the mold. I will be using my Quintax 5 axis to cut the mold.

 

I do have some long tool extentions to use but I dont think they would be long enough to cut in 3 axis from the top.

 

I want to cut with the rotary parralel to the z axis it rotates 365 degrees. and set the other rotary to hold the tool at a 45 degree angle to the table.

 

I created a surface model of the part with a surface revolution of 359.5 degrees.

 

I tried the 5 axis flowline and I get a zigzag 0 to 359.5 back down to 0 like I want but when I enter a tilt angle of 45 degrees it makes no diff. WTF

 

if the tool would aproch the part at 45 degrees up from horizontal it would be exactly what i want.

 

I will try to put the MC9 file in the MC9 folder on the FTP site

OK I got the file on the FTP

ERIC, IT IS almost a sphere shape, u can do that on the lathe just plan turning. verses hours of 4 axis maching. also u can do that 4 axis, align the geomertry excatly the way u will mounted on the table. use flow lines 4 axis. best way is to machin that sphere on the lathe.

Starworlds

thanks for reply

 

BUT

 

we have no lathe here only 3 and 5 axis routers

[Starworlds]

Eric is the material wood or something ?

[JDowe]

It looks like "sidetilt angle" setting controls

that - a setting of 45 looks to set the tool at

th angle you want

[dolphin1]

set axis limits on z axis to 45deg min & max.thats one way.

[Kannon]

how bout turning the part 90 degrees instead of 45, and running a rotary 4th axis?

 

wouldnt that work?

[ERIC14779]

thanks guys

 

this mold is to be out of ren shape polyurethane tooling board.

 

I have to machine it as it is orintated in the MC9 file I put up on the FTP site.

 

I am using my Quintax 5 axis router. all I need to do is get the B axis to stay at 45 degrees from vertical and rotate my C axis (parallel to Z) from 0 to 360 degrees and back zig zag.

[ERIC14779]

I think I got it to do what I want

 

 

I used full 5axis Flowline and set the Z axis rotary to min 45 max 45 as Dolphin1 suggested

 

I think this will work

 

thanks again for the help guys....
