Eeyore-nonhuman forum member, Iskander`s successor, I just wanted to know if you also used Aura-Cad? I remember Iskander replying to one of my posts, and he had used it. What kind of keyboard does a donkey use???

I need a faster keyboard..........

Are you using the filter option when you are creating your tool path???

I will have to agree with Millman^crazy, verify is too slow. If I verified every electrode, cavity and core program, I wouldn’t get much work done. Back plot works well to verify most of the time. I also plot it out on the screen on the Haas, which takes a long time sometimes. Haas needs to work on speeding the back plot up.

Check Screen - Config - Files, look at the data paths for all listed, I think there around 30 there. When I saw your original post on 4-13 I checked the computers in the programming room and found nothing. Then I talked to our designer and I think he found it on his computer. We had a folder doing the same thing as you. I just checked our system and the folder hasn't reappeared as of today.

Justin, I added a file called taperproblem1.zip Hope this helps. Backplot in front view and turn on your tool, the blue line is what you will be cutting with -.005 stock selected. When you pick -.005 it cuts a .005 thick piece off your trode. draw a line at 45 deg then draw another line parallel to it, the parallel line is what you are going to cut to. This works the same as with surfaces and you use neg stock to cut your electrode with a ball or bullnose cutter. Got to go home HTH

Here is the Article Hope this works they want you to subscribe to get to the articles. It works for me but I am logged into the magazine web site.

An article I read a while back might help. Magazine November 2003 issue The article is called "Cutting Tool Selection Impacts the Outcome of Hard Metal Machining" Nice article with charts that might help answer a few questions on hard milling. HTH

O/T Using a Vertical Mill as a Vertical Lathe
Midwest replied to MetalMarvels's topic in Industrial Forum
Just read the posts above. I've done this several times, Core pins and electrodes. I just help a fellow worker program a core pin yesterday on a mill. (his first time) We bought an extended holder a while back for long core pins. -

Just wanted to share an article about HSM. Go to site and look at the Nov. 2003 magazine article and read the article called "Cutting Tool Selection Impacts the Outcome of Hard Metal Machining"

Tony try This site also you can do a search with google for more info on each backgroud program running. This should tell you what they are and if you want them running on your PC.

Another option is to use a bullnose cutter with a radius the same size as your orbit on the EDM. You have to use the spherical orbit to do this.
-
You have to lie about your EM size and lower your TLO by your overburn (per side). If you use neg stock with one cutter and alter the dia. of an other tool in the same program to get square corners in your trode. [ 12-17-2003, 10:54 PM: Message edited by: Midwest ]

+1 on the neg stock and shutoff's quote: I have found that depending on your edm operator (some really hate programming for spherical orbit, which they must do for this to work. Although, I don't know why) you may run into some resistance from them. If you can get them to start programming that way your problems are over. We have a Mits. EDM and programming for a spherical is fast and easy. The only reason I can think of is they take longer to burn and sometimes don't flush as good as some orbits. Our mits has 2 different spherical orbits to choose from.
-
This is what you get when you lie about the cutter dia. The sides move in the amount of the overburn and the top gets a point or edge. Using neg. stock will take an even amount off everywhere on the trode. I use both methods it just depends on your part. Hope the pic. shows OK The picture above could be a sphere or a round shaft.

Try Screen, Next menu, Regenerate

I've used a magnetic chuck a few times on the cnc mill worked great. Just be carefull with the size of part and how aggessive you are with your cuts. Use some of the same principles as if your were on the surface grinder. Use blocks around insert.
