"it has the older Mazak Fusion 640 control."

I guess I'm older than I thought

This continually happened to me on a VF6.

I requested the oil pump be replaced - that was it, no more errors

Thanks for a great explanation Bob

I have an IPhone video, as crude as it is, but it does show a brief glimpse of how things should be done.

Where do you want the uploads?

45 mins against 18 mins and, the procedure was stress free

Before was a 390 Coromill (11mm insert) 1.25" dia. endmill that started bucking as the depth increased (due to radial loading and recutting chips) - still one of my favourite tools!

After was a 3/4" TiAn solid carbide end mill that just ate this application up.

The video was recorded so that our programmer could see this example of dynamic milling in a real application - which was actually ours.

The intention of this video was not for any other reason.

Kudos to Jason Sheldrick of Elliott machine sales in Oakville Ontario for programming it for us.

BTW, the Matsuura MX520 sold 11units in the last 3 months - now that's a quality statement that really delivers!

I ran an application using 3/4" solid carbide, 100% depth and 7% step over, axially 1.75, radially almost 2"

This resulted in virtually stress free results and an increase in productivity of about 300% over plunge and feed cutting; I never would have believed such claims until I actually ran it.

This dynamic milling is really something

I guess I'm going to be the first one to throw this out there.

This is a pipe dream for most of us with 30+ years of experience.

New to cnc machining, lights out operating, a little bit of hard milling (RC60)?

Come on guys, throw me a fricken bone here

I say, purchase all three machines or just cut to the quick and go with 3 Toyoda horizontals.

Such are dreams.

I've been on one of these for 4 months now.

Bulletproof - clearly the smoothest (20K) spindle I've even run.

We have the Renishaw tool laser measurement and probe - this bad boy holds microns day in and out.

Couldn't be happier

The cost makes this a no brainer as well

I just spent two weeks on an MX-520 - excellent machine btw

It's a shot in the dark but it did happen to me once.

Servo Top card error (defective) causing jerking motions - switched with X axis top card and proved the fault.

Wow Joe, you came out of this almost hostile, settle down and talk it through so that we can all learn from the question put forth.

PS, no danger or slight intended

Best Regards, Jack

What was the feedrate?

It looks as if the servos could not keep pace with the programmed feed IMHO

BTW, Gcode is correct about I,J, & K vectoring which makes considerably more code than R values and will slow the interpolation down a bit.

Mazak does make a quality machine tool - you might also float it by Mazak as an open question as well.

Good buy on the camera - nice machine as well

After reading this I envision Florence Henderson aka Mrs. Brady holding on of those blue oiler cans filled with Wessen oil. There she is in a floral top complimented nicely with a mid length grey skirt, 4” spike heels, oversize safety glasses and smiling pertly – one hand on her hip the other triggering the oil can.

Every time I need a shot she instinctively lifts one leg (sort of the way she did when she kissed Mike) the she sets back again returning the hand to her hip while smiling.

After we finish drilling the holes we break into a duet with the Wessonality song.

Thanks for joining the forum just to inform us about Chris's condition Karen, that was very thoughtful.

Hope he's doing well and I hope you can get in touch with Brendan.

Is the diameter the same as a "U size drill"

Otherwise I would disregard thiat callout since it follows no known convention.

Matl: 303SS

Slots are .192 and .235 respectively.

3/16 Slotdrill full depth .125

.02 Axial cut leave .003 radial for finishing with different cutter.

4800rpm .0036"/rev or 17.28"/min

The above gets me through appr. 2000 slots 5/8" long and has consistantly for 12 years.

Carbide and SS don't get along very well IMHO.

4500 psi would take one page of code.

I did this for years in Smartcam and left it to the contracter to substitute the "Y" to "Z" conversion. He was estatic that I could even do this.

Now dealing with the operator is a whole different issue. Running 1500 pcs incomplete means that HE gets to run them all (as in 4500pcs) on a secondary machine tool - but that's just my own thoughts.

I-.01 will shift -.01" in "X"

J-.01 will shift -.01" in "Y"

The critical thing is you must set the tool tip at a quadrant in your spindle, then use the shift variable of "I" or "J" using a positive or negative shift.

PS. Some controls allow a shift amount and direction within a parameter setting.

uneducated rube

Wasn't this phrase last used in Silence of the Lambs?

Between my spouse and I, we have purchased at least ten Dell computer systems including three of their baddest laptops. (at the time).

I just declined the lastest offering from the East Indian rep (constantly called me Mr. Jack) Oh thank you Mr. Jack, blah blah blah.

Most anybody knows me in here, so take it to heart, I will not buy another Dell system.

The hard part is that Dell gets all the latest from Intel and that it takes about 6 months before the resellers can offer the same performance (in Canada anyways)which by that time, is already obselete. It's sort of a catch22; if you want the latest & greatest then you more or less need to go with Dell. If you can hold off for six months then your already too slow.

P.S. I turfed the 9K M170 ensemble and they just won't give up on it .

In aluminum?

Heli-coil uses xxxx sizes and tap drills, they also provide the tap to achieve proper fit. It's one of those propietary things that needs to be done with the correct tools.

Not all suppliers are like this but most are.

Hey Chris,

Perhaps we can get together sometime for a whale blubber sammwich. Low calorie would be best

Best of luck
