Thread Mill Program Issue

[CamNinja]

Hello good people of the internet,

I have a question regarding the output of Thread Mill programs. Im not sure if this is a issue with the post so this may need to be moved. My problem is the code for my Thread mill programs are huge all the arc moves are broken into .002 moves (by huge I mean over a hundred lines for one pass around on a 1/2-13). I believe that the program would run ok but it is so large and cumbersome I dont even want to load it. I have posted out interpulation programs and they are normal. I have tried to post it with some other posts and its the same way. do I have something set to sensitive. I have searched around but I havent found anyone else who has complained about this, Any help or suggestions are greatly appriciated.

Thank You

There is a switch to linearize arcs, if that is checked, uncheck it

I found a linearize Helixes (turns my arc into a triangle) which is not checked. The only linearize arcs i found are for Surface toolpaths?

[Guest]

How about right here in the threadmill toopath?

 

 

[Guest]

If that's unchecked and you still don't get helixes, check this setting in the control def

I'm not having a problem getting getting the helixes the problem is that it isnt posting out as a couple line arc move here is an example of one pass on one hole.

Actually what you're getting there is not a helix.

 

A true helix would look like below, the settings I suggested should get you here.

You are correct,

I will follow all suggestions before I reply next time. No heliex allowed was selected.

[Guest]

lol, glad you got it

 

[ChrisB76]

I am having this same problem and my "No Heliex Allowed" is NOT checked. What else could it be? I am creating the same thread in two different files, it posts correct for one, but the other comes out as little lines.

[steveo25]

Did you look under machine definition/control definition/arcs/mill and make sure all planes were supported?

[crazy^millman]

If not there and using a legacy V9 post look for a switch that forces this.
