Here is what I'm doing: Create/Line/Endpoint and I make sure Tangent is selected. I hover close to the first arc, it highlights and I select it. I hover close to the second arc and it............HIGHLIGHTS! I selected it and it drew a line tangent to two arcs!!!!  I can't tell you how many times I tried the same thing last week and it just refused to work. I guess it just needed a rest over the weekend. Boy am I glad I got that to work, it was driving me nuts.

I thank you all for being patient with me while I beat it into submission!

Thanks for the replies. I must have something set wrong. I hover close to the first arc till it changes color and then I select it. When I hover close to the second arc it will not change color but will hi light a point on the arc such as the end point or the mid point.

Hello everyone,

Please excuse my question, it seems so simple to me but I am failing miserably to create a line that is tangent to two arcs.....

I have X9 mill and wire

Thanks

It works great.....so glad I got on here and asked. You guys are great, thanks!

Hey Rickster, what is "Thee Circle"?

Hey guys thanks for the quick response! I've got signed up for Mastercam.com and downloaded the zip. I'll give an update when I can.......gaining knowledge daily!  I did notice....181 views on this post. Wow, there's a lot of people on here. Cool

Thanks Bear,

Please pardon my ignorance but where do I find c-hooks?

Hello everyone,

I am on version X8 (wire EDM) and need to wire a lot of holes in a mold cavity. The way I am doing it now is I have created wire thread points for a series of holes on a level by themselves. Then I create another set of thread points on a different level that will have a different diameter.....so forth and so on. In all its close to 100 holes of 4 different diameters, each diameter is on a level by itself. Now that I have all my thread points created, I turn off all but one level: create arc-circle center point-select my thread point and give it a diameter.

Is there a way to select all the points on that level and give a diameter and create arcs  with just a few keystrokes rather than selecting each individual point?

Thanks guys for your help!

I took a closer look at this and when I # those lines out of the post, I lose G1 at the begining of the program as well as G0 being removed. It's got to be something that is putting the rapid feedrate in the NCI code.

I got it to work by putting # in front of these lines:

code:

-------------------------------------------------

if cntrflag = one, g20code = one

else, g20code = zero

g30code = g20code

(I don't understand what these lines do but it didn't change anything other than removing the G0.)

-------------------------------------------------

code

-------------------------------------------------

cntrflag : 0 #Contour flag, 0 = before, 1 = contour, 2 = after

#3 = single move case.

(I tried changing to 1, 2 or 3 but it didn't make any difference.)

-------------------------------------------------

NCI code:

-------------------------------------------------

-0.9 0.1 0.

I think it has something to do with ".300" which is a rapid feedrate but where does that come from?

Heavy,

What kind of parts do you usually make?

Heavy,

Blind holes are for cascades or baffles. .578 diameter is for 3/8 NPT, you can use 9/16 drill and pipe reamer, then tap. I drill .2 shy of depth and hand grind a ball on the end of a drill and just drill the last .2 with the ball drill. 2" is pretty shallow, on deep holes I have drilled with on size drill then balled with 1/64 under so drill would not seize in hole.

Hey, this is kinda cool. Finally I can contribute, its not easy to do when your using Ver 8.1!

-------------------

Wire 8.1.1

Heavy,

5/16 ejector pin measures .312 so I drill and ream .313 before heat treat. 3/4" of bearing surface is common, with the rest of the hole relief drilled 1/32 over. I have seen it before but it is rare that customer wants .002 over pin size. Aluminum flashes at .003. I agree with Kevangle, 4" not too deep. I would go from BS also.

It seems so simple but I gotta ask for help. I've seen others have success getting a G92 after every G0 with Ver 9 and X. Has anyone tried to do it with Ver 8.1.1?

Thanks for your help,

Hi guys,

I have a similar problem but can't seem to get it to work. I've got three pockets to wire out and I'm using two operations to do it. The first operation roughs all three leaving a tab and then cuts tabs in reverse. The next operation skims all three. The problem is I need to remove the slug before skimming starts. I tried Change at Point and it puts M00 at beginning of rough pass. Hmmmm,any thoughts?
