Problem with Lathe verify

[Leigh @ Kodiak]

I'm pretty new to MC Lathe, so I'm sure my problem is just something silly that I have missed.

 

 

xxxx you can see in the picture, my tool path and stock display are clearly showing as being horizontal, but when I run in Verify it shows as machining in a taper. Also when running verify, the tool is making movements that are not in the tool path.

 

Anybody have any guesses as to what I am doing wrong?

if you are using control comp , simply forgot verify

 

set your TNR at 0.0 ans use wear , then compensate the radius in the machine

 

IMHO cutter comp is a PITA with mastercam

What kind of boring bar are you using? It looks like the chamfer isn't the same.

 

I have run into similar problems and I have tracked them down to how I defined my boring tools.

for some reason my boring bar shows always across parts( the wrong way) using verify only as second ref........ backplot is my tool for now (lathe).

maybe cnc software will get this fix on mu2.

I have had simular issues never really got much help... still mostly unresolved. Is this simular to your problem?

 

look for the link "backplot vs verify"

 

you may notice the taper in the screen shot.

This looks like a Control Comp issue to me

There is a setting at:

System Config

Verify Interface

Verify Settings

"Cutter Comp in Control"

Is it checked or unchecked..

try it both ways and see if it helps

You may need to restart Mastercam

for setting changes to take effect

If you are using Control Comp

try it with computer comp.

No its your boring bore. Its to big for the hole and on the pull off moves, its hitting on the back side of your boring bar even though you only have half the part drawn.. edit the tool to make it smaller..

Never really determined what the issue was here. At the suggestion of my re-seller, I reprogrammed the part using top as WCS. For some reason, MC creates a plane the same as TOP all on it's own to use as TPlane and Cplane. This new plane is the same as TOP plane Have not ran into this same problem since.

 

I used all the same tools, posts, machine defs, verify settings etc. Only thing I did different was chance the default WCS.

 

I just want to say here that some of the behaviors in Lathe seem mystifying to me. Just as I think I have it figured out and cruising along, some other oddity will crop up to ruin my day.
