I have older Agie 150, I am having trouble getting the ID good on my tapper , my angle good but the ID is way big , I am programing with esprit , its like not see the H value in the job file

mintonr,

From your post I believe you mean taper, and are trying to wire-edm a tapered hole of some sort.

I am not familiar with Agie machines and controls, at least not before their merger with Charmilles, but it would be helpful to us if you would describe your situation in a little more detail.

Is the taper being cut 'up' or 'down'? In other words, is the big end of the opening up or down?

Are you cutting in taper or 4-axis mode?

How much over-size are your holes?

What tolerance are you trying to hold?

Where are your program and reference planes in reference to Z-zero?

Has the machine cut taper correctly before?

If we were talking about an Charmilles, or Agie-Charmilles machine there are several things that might cause this.

Among them are:

1. Incorrect, or no, offset being picked-up.

2. Incorrect program plane height.

3. On very tight tolerances and/or high angle tapers, not accounting for the increased kerf-width caused by the wire's now elliptical cross-section.

Machine Agie 150 MMD WIRE EDM year 1994
.I am cutting it in two axis ( conic) the part has two different angles, machine didn't like 4 axis specially since it oblong
.its and oblong hole, width is .41mm long and the length is 1.37 mm long tolerance +- .012 microns
.reference plane is 2.742 from ZO
.has cut tapers good before but always had trouble with taper hole
.small hole on bottom big on top

it's like it doesn't see the H value in the job file

H1=0 H2= 2.742 H3 5.51

[KilrB]

Bear in mind that I am unfamiliar with your machine.

The Charmilles and Agie-Charmilles I run have a single H value that is the part height.

It appears that on your machine:

H1 is the program plane height in 'Z'

H2 is the reference plane height in 'Z'

H3 is ? ... total part height?

You are cutting a conic taper ... with two different angles.

Do you mean that you are cutting a double angle taper, or that the taper is not the same around the entire slot?

On the machines that I am familiar with, the reference plane does not come into play when cutting a conic taper.

Only the program plane and angle are needed.

The reference plane IS necessary for cutting in 4-axis mode.

Are your holes going over-size on the first, second, or both angles?

Is this a die?

If you are cutting a die and leaving any kind of land, remember that your program plane is no longer @ 'Z'-zero but at the height of your land.

[mintonr]

Yes H3 is total height

yes the taper is not the same around the entire slot and it is die

and yes its oversize on both angles ( but the angles are good)

there is no land on the angle

[KilrB]

I hope that someone who is familiar with your machine and/or Esprit speaks up soon.

You are cutting a conic taper, but not at a constant angle.

The angle changes as you are cutting around the slot.

I know it can be done with just the program plane and an angle called out, and have done so, but I usually opt for 4-axis any time I have to do this as I find it easier.

Knowing how much you are oversize, can you correct with additional 'clearance' or adjust your offsets?

On the machines I run there is a setting called CLE that can be used to adjust the finish size +/- if necessary.

Just out of curiosity, with the varying taper angle, is this an extrusion die?

It's been a very long time since I did any extrusion die work, it's all progressive blanking and forming where I work now.

[mintonr]

I tried to offset but I could the width good but not the length

[KilrB]

Just looked at your dimensions again, that is a small.

Where is your program plane in 'Z'?

Is it possible your program plane is being placed @ H2 where your reference plane would normally be when it should be @ H1?

[mintonr]

plane is 2.741 and I've try H1= 2.741 and H2= 0 and then H1= 0 AND H2= 2.741 nothing change

[mintonr]

more info
1.127 mm x 2.02 mm

[KilrB]

You're swapping your program and reference planes and nothing changes?

At the very least it should invert the taper, in my experience.

[mintonr]

I am changing my planes in my job file ( h1 h2 h3) not my program,

[KilrB]

You're still changing your plane elevations.

You should still see a noticeable difference.

Have you tried calling Agie-Charmilles?

They have always been very helpful when we have.

They have, at least until now, required only a company name and a model and serial number to help.

[mintonr]

I do have a call in to Agie-Charmilles waiting on a call back

[KilrB]

Well sir, I hope they can help you more than I have.

[mintonr]

Thanks for your help I really appreciate

[mintonr]

update
got it figure out, in the job file you have to but the H1 H2 H3 AND CNC ANG PRO codes before the GEO file, and thanks again for input
