My two 4 axis Haas post processors (VF2)

[DiegoM]

Here are the 2 post processors that I got for my haas mill. Both are not working as expected with the A axis. The problem that I have is that in "mill mode" the 4 axis button does not activate. Because of this I cant machine a surface using the A axis simultaneously with other axis (a helix for example). I tried making a new post processor from the haas template but i cant mange to make it work (the same problem) even if I do declare or activate a 4 axis during the new post creation.

Does anybody knows what to do? anyone with a haas post that works with 4 axis simultaneously?

Thanks in advance!

hey man... i got your private message..
someone at edgecam gave me a post processor.. and it still doesnt work worth a damn for simultanious 4 axis machining.... but it does work pretty good if you are machining pockets using unwrapped geometry..and even then its more like 3 plus 1 machining.
i feel your pain ... i have probably built a dozen or so post processors from the given templates...somtimes it works..but most of the time it doesnt. i have even went as far as using a five axis template and removing "everything b"...
i have wanted to highspeed machine helical gear shaped parts or wing type parts with a ball end mill fixed and the a rotating under it..instead of indexing and 3d contouring and indexing and so on.... i just dont think that edgecam is capable of this type of milling... if so ..i havnt seen it. i will pm you my email addy...there are a bunch of things you can do as work arounds that i have became quite good at ,that i will share.... i dont get on this forum to often because its slower than hell...

Guys,

What format are you wanting on the code?

I'm getting this for 4th ax sim ....

Whereas yours is different with the G107 and wrap height.

A couple of other things as well
1) have you got the licence for rotary?
2) in edgecam have you switched to rotary mode

When creating new posts in the future always choose the adaptive templates. In milling choose either the adaptive-mill-iso or the adaptive-mill-tnc

Hope this helps

If you dont have a button (it's greyed out), it means you dont have that feature. The Edgecam menus are dynamic, so only the functions of your software will have active buttons. If your sure your should have that feature, I'd call my dealer and ask him.

Calling the dealer is a great suggestion as they probably also have thousands of customers using EdgeCAM 4 Axis and Haas machines.

is there any way to adjust the angular increment in the post pro.the feed rate looks like its set up for inverse time feed... and on haas i thought that every feed move has to be accompanied by a (inverse time) feedrate.
i used the 5 axis cycle to try to machine a wing shaped part...and it looks perfect in edgcam and the simulator... it just dosnt work so hot on the machine...it posted way to much code for the machine to read... and i have a haas superspeed with the look ahead algorithym deal...!!
i wish there was a 4 axis cycle... lol

I had trouble with the rotary not working, called tech support for as much help as they were, all the wanted to do was sell me the next level higher for synchronized 4and 5 axies milling, and we already have the advanced production kit.
In the end he really didnt help me and i still dont know how to make the y axies lock up and all the movements made by the rotatry for all jobs but I did have some luck on some jobs when i made a rapid move to y0 ,turned on rotary mode, and in the machine roughing i put the stock type to none,then all movments were made by the rotary

Also you mught have to right click on the sock feature on the left of the screen and click "primary rotary axies"

they weren't trying to "upsell" you. in edgecam you cannot machine a solid model or a surface with the 4 axis sim. milling. you can machine wireframe geometry in rotary, If oyu have a model to machine, you can extract edges with the geometry from edges command and then use a piece of the shareware/freeware called power unwrap. then you're standard cycles which are included in advanced production.
