Stock doesn't show being cut?

eric.lefavour · 2010-03-16 13:02:00

My model does not show material being removed from workpiece? Any help? Tool appears to be into the material, but there is no removal of material.
Thanks,
Eric

First always post the version you are using, best is to create a signature, which includes relevant information, see mine.

There are situations, where VC thinks you have a multi-axis tool path, but you have not.

You will have to check if multi-axis verification is enabled.

Where can I find the "multi-axis verification"? Also, the machine is a mill/turn, so there are multiple axis. How will this affect the machine model later? Thank you Stpendl

Hey Eric. I also use v6.1.2. with multi-axis, and I have noticed that sometimes, on some of my machines, I get the same problem. A cutter will bury itself in the stock but the stock looks untouched. Generally this only happens when I put the fixture model(s) into the stock branch of the project tree. Try making sure that your fixture (tombstone, vise, whatever) is in the fixture branch. I have no idea why this works, or why it only happens sometimes. The other thing I would check is to make sure that the view you are using is the "Machine + Cut Stock" view, as opposed to just "Machine," as the Machine view is to show just the machine motion, not the material removal. Just right click in the view window, rollover View Type, and select either "Workpiece" or "Machine + Cut Stock." Hopefully one of these should fix it.

Good Luck!

Mikefitz,
Thanks for the help. I tried your advice, but had no success. I'm trying to build a Tsugami TMA8 and am having lots of trouble. At the point I am at right now, I can get the machine to move, but still can't cut. The process I am working on right now is just a simple turn and cut. Starting with the basics and not having much success at this point. I do have a tool in the spindle, and it offsets like the machine knows it's there. I even removed the fixture altogether, which in this case is just a Micro-centric chuck. Still no cutting going on. Also, I use a macro in the first positional line, like this G0G54G96X[#500+.05]Z0 for example. Where the #500=stock diameter. I have noticed that when my G71 routine is running(where it should be cutting stock), my status window never shows "X" moving from the original [#500+.05] position. Even though my model is showing it, is that normal, or a key to my problem? I'm pretty new to Vericut and am limited for resources right now. Training may be available down the road, but for today, I need all the help I can get.

Do you have any error message when the tool is in the part?

To remove material, the stock must be visible at least in the Workpiece view. In the Project Tree, right-click on the Stock Component, Visibility = Both Views.

When you are in turning mode, your machine must be configured to let VERICUT know what is the cutting mode (milling ot turning).

Part spinning + tool stationary = turning
Part stationary + tool spinning = milling
Part stationary + tool stationary = no material removal and error.

To spin the part, the Stock must be attached to a Spindle component. The M3/M4/M5 must specify which spindle is spinning. refer to the turning samples for examples of the configuration.

For a quick test, you can test if your stock spins correctly, right-click in the animation window, Display Axis> Spindle Direction.

SergeV,
I did your check for the spindle axis. It looks correct to me, the axis points straight down my Z axis. I cross-checked it to my Puma Lathe model that does work and it was the same. I also put the machine in MDI and gave it an M3. My fixture was spinning and it is connected to the same "Attach" as my Stock. So I believe it is spinning. I have a notion the problem may be in my tool. I don't seem to be making tool changes. I'm not really sure how to make that work correctly. If I put a tool in my tool list, I get one in the spindle. It doesn't change though when the next tool should come up. So I may have something wrong there? Could that possibly be why the stock doesn't seem to cut. I am a bit puzzled that my "X" in my status screen doesn't change when my G71 canned cycle is roughing off the material. Is that another indication that the problem is in my tool?

I did find that in my machine settings, the "Ignore Collision between Cutter and Stock" was set to "Active Tool". I switched it to "No" and got an error message that "Tool CUTTER" gouged the "Stock" at line :.......... What does this tell me?

Perhaps take a look at the cut tolerance. I had a machine where the tool motion did not remove material. It was a pc processor issue. If I opened up the cut tolerance, then the material would display being removed.
Basically, your pc is not robust enough to display the stock removal, so Vericut just skips it and moves forward.
They are aware of the issue and it is to fixed in a future release..

Hope that helps.
