EDM Sinker programming with MC ?

[Jeremiah]

Hello everyone-

 

I haven't posted in a while, but now I need you. I am trying to help out our EDM shop by programming a part that will require 6 different burns. The machine is a Mitsubishi EA30 with a C axis. Each trode will need to burn with the C axis at a set rotation and travel along a 3d vector. I have designed a tooling ball into the fixture for the trodes to touch off on and will write a macro to update the offsets. I plan to use MC to program the xyz positioning. I am hoping some one in here has done this before and am looking for comments, post suggestions, etc.

 

Thanks and good to see you all.

why are you trying to use mastercam to program this? does your contoller not have esper or fap programing on it?

[Jeremiah]

kamman25-

Yes it does have espers. Obviously it has the ability to probe, but would I then edit the program for the macros, or what? Bear with me as I am EDM programming iliterate.

 

Thanks for the reply

i ran the same controller a few years ago so i may be a bit fuzzy myself. do they not have the time in edm dept. or are you just seeing if it can be done?

i think it can be done but you would have to edit alot at the contoller.

 

are you burning at an angle, rotating c axis as it burns, or just different positions?

[kamman25]

sorry just reread your first post. that type of burn should only take 10 or 15 min. to write in esper.

[Jeremiah]

I think it is going to take more than what esper has to offer. This is what I need the program to do.

 

1. With trode #1 in spindle.

2. Position over check pin to ensure correct trode is loaded, alarm out if not, continue on if o.k.

3. Index C and probe trode face.

4. Index C, pos XYZ, follow vector to burn depth with orbit.

4. Change trode and repeat steps above.

 

So should I start from scratch or what ?

sorry, just got back. what year is your machine? do they still have fap proraming on them? i took the mits class in 2001, but they were talking about getting rid of FAP progamming, i know you could do it in that.

[kamman25]

gave all my notes and books to the guy that replaced me, but i remember doing what your asking right at the control. why cant you touch all your electodes off before starting the program

[Jeremiah]

The machine is an 04 and uses E.S.P.E.R. 2. We don't have a toolchanger so in an attempt to idiot proof the process, each trode will be calibrated (probed) prior to burning. I have found an old g code program of a similar part from several years back and will be writing the new code based on this.

 

Thanks

if you can talk the owner into it, get the tool changer it is very nice. many times i could touch off all my electrodes just before i went home and have a finished mold when i came in the next morning

 

sorry i couldn't help more

Jeremiah,

Try to call Mits support center, I know one of the tech guy's for wire, who in the past have send me macro's for my wire.

Maybe your program is already written, laying in some tech guy's draw, and waiting to be copyed on a disk and send to you.

Thanks for you input. I am almost there. I have most of the programs written, just need to plug in the vectors, just, ha ha. Will start with a main calling 6 subs, 1 for each trode, then 2 subs within the subs for conditional statements.

 

Have a great 4th.
