Agiecut 100 Programming/Tech Question
When cutting tall parts I have a small issue that happens occasionally and I am wondering if there might be a simple programming\tech change that might solve it.
I have attached the roughing program that I often use so you can get the idea of what I am talking about.
The issue - everything is perfect cutting around to the stop where I then shim up the slug and cut off the tab. However when breaking through the tab at the very last few thousandths the machine will usually stop and back up a few times trying to get through without shorting the wire.
On occasion it will back up pretty far and almost get a run at it and when that happens it will jump over the ridge left at the end instead of cutting it off smoothly. When it happens it is to much for the skims to clean up and I wind up with a ridge.
My question is can I jump in just before it breaks through the tab and change the tech to something that would cause it to slow down and burn through without stopping or backing up and if so what would that look like in my program below.
Also what would I change on my tech to cause that to happen?
Skim 1 begins here.
These are the tech numbers that I am using. M=5 T=12 I=10 PR=30 P=5 Td=27.5 Hc=11

There is a number of ways you can do what you describe, some depends on what you're using to program with.
When you restart after fixing your slug, just go to erosion T page and lower the P value down to maybe 2. This change will only be in effect until the next element number which in your case is the entry line.
Depending on your programming system you can set a power down distance of your choice. Agie programs typically use the T96 S96 register for this purpose.
Also you could just add those parameters manually to your geo file on the line following the stop.
I would be glad to help more if you need me to. I think you have my number.

Thanks Jeff, I do have your number and may give you a call.
The machine is a little old for a geo. file.
What you see there is the entire program. The tech numbers are changed right on the machine. Then the header in the program calls out which tech line to use. I think I can have 99 of them.
You are correct any manual change stays until the program hits the next entry. I will try lowering the P and see what happens.
For some reason I was thinking I needed more power and less speed and wasn't sure how to accomplish that.
By the way, that pump setup you pointed me to is still working great!

Glad to here your pump is doing ok.
Now, back to the tec issue. Add T96 S96 to the end of the line following the M00. Have those values preset to your desire. The machine should run the rest of the main cut with those settings. If you can rotate your entry for the trim passes, it will eliminate ang witness mark from the lead in line. This is something I do often. I hope I am understanding correctly what you are trying to accomplish. Good luck.

Have you tried stopping the cut just before it breaks through the tab? If there's just a few thou, you should be able to pull your shims & break it off by hand, no?

The slug is 8 plus inches tall and internal so it's pretty tough to get enough movement to break it and there is no possibility of grinding or filing the break afterwards.
I just need to consistently get a nice smooth cut. Most of the time it comes off perfect. I am just trying to fix the occasional issue.
