post for G91 and single quadrant G02/03

[Karl_T]

We've been looking high and low for a way to post to our new to us ,very old wire EDM (Charmilles Andrew). Calls to the dealer didn't help.

This machine is allways in relative mode, G91. And all circular moves can only be in one quadrant. It takes four G02/03 moves to do a complete circle.

Does anyone know how to modify a post for these two requirements?

you have a pm!

Step 1:
Make a COPY of your .pst file.

Step 2:
Open in a TEXT editor like notepad.

Step 3:
Look for "breakarcs : 0"

Step 4:
Change the 0 to a 1

Step 5:
Save the file.

Step 6:
Do your toolpath with Misc Values Integer #2 set to 1
I have no experience with wire, but I think it will still work.

Step 7:
BE CAREFUL! and test before you cut.

Setting breakarcs to 1 is an option but it will then not output any arc moves and will generate linear segments in place of them. The linear segments will be determined by tolerance set also in the post.

I believe he is looking for the arcs to be broken at the quadrents which needs to be set in the control definition in X2 under the "Arc" topic.

Alex,

Since he does not specify which version of Mcam he is using, you may be correct for McamX.

If you look at the pst file you will see a line that reads:

breakarcs : 2 #Break arcs, 0 = no, 1 = quadrants, 2 = 180deg. max arcs

Or in McamX:

breakarcs$ : 2 #CD_VAR Break arcs, 0 = no, 1 = quadrants, 2 = 180deg. max arcs

So, I am correct for Mcam9 and earlier.

I apoligise, I mis read your post ObreinDave I thought I read that you were referring to the "linarc" variable instead of "breakarc".

Yes you are correct with your post.
