Coolant?

MIKEFITZ · 2010-05-21 11:29:32

Anyone ever have problems where the lack of an M8 will cause the cutter comp to be processed differently than the way it is supposed to?

SergeV · 2010-05-21 16:21:21

That seems odd. What are the lines of code? What is the effect?

It starts off more or less ok, but then I start getting bigger and bigger circles, and everything hits the fan. This is without coolant. When I put an M8, then everything works fine. im so very confused. This doesn't happen everytime, but definitely often enough to present a problem. It's like without coolant, the comp goes crazy.

I forgot to mention in my first post- in my control, I have M8 set with CoolantFlood, and a variable named coolant with a value of 1. Not sure if that has any bearing on my situation, but I figured I'd throw it out there.

Hi Mike

I suggest you take a look at the cutcom part of the control in the word / address area. See if you have a conditional thing set that may not make sence like if g42 and variables so an so.

Also see what macros are called by the m08

Just taking a wild guess at it

Hey folks.

Latest on the coolant problem... originally, the problem was only in my DMG DMC 60 T w/ MillPlus IT control. Any time I did a helical move without coolant turned on, the tool would carve an ever-increasing spiral through the part, fixture, and whatever else. As soon as I put the coolant command back in, the machine behaved itself.

Now I have run into an issue with tapping on my Okuma MX-55. On a particular job, we want the operator to use Moly-Dee on the tapped holes instead of the machine's coolant. No big deal, right? Well, Apparently, when there is no M08 in the program, it never switches out of rapid, never updates the feedrate, and gives me Fast Feed errors for each tapped hole.

The problem is fixed with the addition of a M08. :?

It's not even a big deal, more of an annoyance really, but I'm curious anyway.

Any one else see anything like this?

Hi Mike,

This doesn't compute :? , there is no relationship between the coolant in VERICUT and either Cutter Compensation or drilling cycles. All it does in the simulation is update a flag in the Status window.

Please contact Technical Support, someone should look at your files and investigate what causes this.

Thanks,

I am curious too!!!

In Advanced Control Options make a substitution /M8 = M8.
