Accept recommendation about Robofil CHARMILLES installation and training technician.
Looks like Justin got banned from this forum - probably because he's busy fixing stuff & isn't as prone to take the time to give a lot of advice in this format; He's a service tech, not an end user. Bottom line is, he knows Charmilles inside & out. You can still find his info on this thread...- OffsetLeft

Fanuc Robocut Open shape offset ramp on question..
Why the discrete start & end points? A 'thread' point at X4. Y-2. would provide a perpendicular move to & from the profile on something small like this. If that were 8" instead of 8mm, then discrete points would make sense, but I'd still put them inside the profile, say X0.1 Y-0.1 and X7.9...- OffsetLeft

440c rusting in wire EDM tank
Just to be clear, for the sake of the OP; most machines use a resistivity approach, I've run some that measure conductivity. That being said, raising the resistivity is the same as lowering the conductivity and vice versa. I'm certain that making the dielectric less conductive is what's called...- OffsetLeft

EDM Wire
What's the old NC milling adage? - increase your feed until the tool breaks, then back off a tick, right? If you're getting wire breaks at .070", then you're actually going much slower. Back it down to .065" - you'll still get the speed advantages without the stoppages, and come out way ahead.- OffsetLeft

Filter blown?
"Little streams" shooting out the sides of the filter means that there are little holes in the filter media. When this happens, dirt that is supposed to get trapped by the filter gets into your clean tank. Time to shut 'er down & swap in some fresh filters. Some machines put all the water...- OffsetLeft

Dedicated User
My guess is this is a shared asset for the shop with no 'wire guy'. Everybody sets up their own cuts and apparently has their own way of doing things. Makes you wonder who maintains it (nobody)- OffsetLeft

Mitsubishi 1200s
With Mitsubishi, you have to be willing to 'join the club' to obtain parts & service from the OEM - I don't know the details of the yearly cost, but if you're considering buying a Mits, you should find out how much it is, and factor it into your decision.- OffsetLeft

1996 Charmilles Robofil 510 Measurement Cycle Inefficiency
Instead of running the canned 'Center Find' cycle, you could write a macro that starts near one quadrant point with an edge pickup, record that point, rapid across to the 2nd point, edge pickup, do some math to find the midpoint, then do a similar routine on the other axis, then repeat the whole...- OffsetLeft

Wire Differences
My $.02? As long as you're happy with the cleanliness and thread-ability of your chosen wire, and it gives you consistent, dependable results, there's no good reason to use MC wire. Dan- OffsetLeft

Wiring Tapered Holes Results in a Bunch of Tiny Flats
You should still be able to run slugless with a 'hybrid' program that starts with the pocketing, then uses your arc & taper for the finish passes. Best of both worlds ;)- OffsetLeft

Mits FX10 WEDM Corner pickup
I haven't run an FX, and it's been some time since I ran a Mits, but if there MAINT and/or Switch screens, I feel like there's bound to be an option to 'cut wire after pickup' or something like that. Check or uncheck as appropriate.- OffsetLeft

Robfil 510 Wire Offset Generating Weird Geometry
Hm. I've run Charmilles machines, but I'm not so versed with the controls to know why you'd still be getting an arc that's not written into the program. It's gotta be some toggle somewhere in the control that sees a small corner and applies some automatic intervention - anyone else have an...- OffsetLeft

Dealing with slugs
There's more than one way to skin a cat, but trying to drop a 10mm x 100mm slug unattended just isn't a good idea, IMHO. You'd be far better off to pop a series of start holes, 20 or so mm apart, make your program according to that spacing so that it roughs all the IDs to a tab, one after the...- OffsetLeft

Robfil 510 Wire Offset Generating Weird Geometry
I used to have this problem with older AGIE machines that I ran; programming to the profile and offsetting at the machine would result in a garbage corner if the offset was too big for the corner radius. Eventually, I figured out that by writing the offsets into the program instead of letting...- OffsetLeft

Where do you buy your wire?
It's been a while, but when I ran AGIE machines, I switched from the (OEM recommended) CobraCut A to StammCut - that I bought from Electrodes Inc. It ran clean and gave me the same results as CCA at around half the price (in 2012).- OffsetLeft
