Verify--drilling error?

[ChrisD]

Good Morning,

 

I have been working on a cavity plate which requires a few cavity pin holes. When I programmed the drilling operations I used incremental top of stock and retract when I verified the program it was fine.... at the the machine was a different story though.

 

The center drill crashed into the cavity ruining the parting line. I noticed in the program that the R value was way too deep. I know I should be a little more diligent in checking the actual NC Code bur I thought Verify would pick a crash like that.... And yes I did have the Stop On Collision button on. Any Explanations? Or has this happened to anyone else?

 

TIA

Have you checked to make sure your clearance plane was either set to incremental or at least set above the part?

did you have tip comp on.i have had it give some crazy z depths with that on

JmParis,

 

Yes, the clearance plane was set to absolute 2.00 retract was set to inc .1

top of stock set to inc zero. When I selected the actual drilling points though, one of the arcs was selected below the actual drilling start point causing the tool to want to start drilling 1.875 (rapid) into solid material. I realize that error is on my hands. I am just wondering why it did not show up in Mastercam Verify.

 

Thanks,

Did you have verfiy set to stop on collision? Did you run through the verfiy and just not see where to drill was starting at?

when i program for drilling i will

run back plot in the front view

this is where i see where the drill

will be starting at,when i have different

starting depths.i will also run verify.

but i will catch all my mistakes for

drilling in back plot.

Yes, STOP ON COLLISION was checked on. I seem to remember in version 8 if the drill was rapiding down into material, it would give the "Stopped on Collision" message and stop the verify, and you could continue on if you wanted.

Chris,

We have that problem all the time if using incremental drilling depths, which is why we don't use them anymore. It must be a post tweak because verify AND backplot miss it.

Hey Chris

 

Sorry to hear about the boo-boo. Could you email me the file?

 

Did the boss rip your head off? I don't see why verify wouldn't catch it, but I will have a better idea after I see the file.
