I CAN'T BELIEVE I COULD NOT SEE THAT LINE!!

Thank you

Hello all

Our resident Fadal guy is off on holidays so I have been struggling to twist my HAAS wired brain to work on the Fadal. He has never used mastercam to its full potential the programs are an mix of manual, mastercam and smartcam. So I have been trying to post my MC9.1 files to work on the Fadal with a new MPMASTER_FADAL post. So far it seems to have been working quite well (except for having to find way to fit in the control) until I tried to post for the 4th axis. The post is sending the tool home and stopping whenever there is a A move? I've been "attempting" to fix this problem myself but with my vary limited post knowledge I've just managed to waste time (and learn a couple of new thing about posts as well).

Any ideas on how I might fix this?

Thank you

Check the tools section. There is a free c-hook there called GD&T it might work for you

my book says alarm 134:

When UNCLAMPING, the tool did not release from the spindle when comanded. Check air pressure and solenoid circuit breaker CB4. Can also be caused by misadjustment of drawbar assembly.

If this all seems ok it could be you limit switch may may have bit it. I've had to change a couple on our HAAS mills in the past. Check your on the diagnostics page I think all of the machines limit switches are listed there and the numbers change from 1 to 0 ( or vice vesa) when they are activated. Might help to see if they are working or not.

The haas uses nitrogen as a counter balance for the head of the machine. If it is low it may be causing your problem. Does you machine generate and alarm?

how is our air pressure?

In the HAAS control there is a handy find and replace function. Great for replacing D values.

Just wondering why you need to get rid of the D callout? If it is a file size issue I'm not sure if it is worth getting rid of a D callout to save space. Yes it is redundant but it is there for safely. You might want to lose the line numbers and spaces to shrink the file size.

I would think projecting the letters on the surface would be best if you will be machining from the top.

From MC help:

You can project an NCI file (created prior to entering the Project toolpath function) onto any sphere whose radius does not exceed certain limits.

The arc you select to define the sphere’s cross-section determines the sphere’s center (arc center), Z coordinate of the sphere center (Z coordinate of the arc center), sphere radius (arc radius), and the concave or convex shape of the projection surface. To define a concave sphere, select an arc whose midpoint lies below its center. To define a convex sphere, select an arc whose midpoint lies above its center.

1. Choose Main Menu, Toolpaths, Next menu, Project, Sphere.

2. Select an arc that defines a cross-section of the sphere. If the midpoint and center of the selected arc are at equal heights, the system prompts you to choose either the upper (Z+) or lower (Z-) half.

3. Enter the Project parameters in the Project Parameters dialog box.

4. Choose OK. The toolpath is added to the Operations Manager.

Note: You can also project a toolpath on a sphere by choosing Toolpaths, Project, Sphere from the right-click menu of the Operations Manager.

I"ve recieved it too. Man he has balls ....At the moment

In the control perameters there is a switch for "repeat rigid tap" (I believe it is an option) With this on, the HAAS will orientate the spindle each time before tapping a hole making it possible to repeat tap a thread as long as you start from the same position.

opps

Yes you can copy and change the z depth. BUT your HAAS has to be set up for repeat tapping.

You might want to try a graphics shop. I belive most of them have a computer controled cutter that would probably work well for gaskets.

Hello from British Columbia, Canada.

You can use the T-helix c-hook. In the past I've had trouble to get depth cuts to work with the 3axis rotary toolpath. Had to draw it flat and use axis substitution to get depth cuts to work. It worked well but there was a bit of unwinding of the rotary.

At least when our HAAS needs a repair man he can be here the next day or sooner. The mori guy we have to fly out $$$$ (I think ).

Something to think about.

Ok I read much gooder now at the question.

Could it be that one of your tools is flaged as oversize in the control?

You could try and search in you post for "stage tool" if it in there just change the 0 to a 1 and that should do it.

Thanks Mark That sound easy enough....I think hehe

Hello

I seem to be having a hard time getting it to wark as well. Have you tried creating a helix down the center of the groove then unrolling it and using an axis substitution toolpath? Unfortunately in the past I have wussed out and went that route when time ran out.

Thanks Mark

I'm not sure what to do with it? Reading the pst file I get lost on the 3rd line.. hehe

"INPUT: Dummy -.NCI file (MP needs the -.NCI name. Just make a file with the sprocket name with the word 'dummy' in it.)"

Where do I make this file? Sorry if this is a Dummy question.

Are you using a form tool cutting on center to get the shape?

Thanks for Trial version Dave. I'll give it a try in a bit.

Oh $100 I didn't know that. Thanks

I guess I'll have to figure out how to get the Gear c-hook to work

Thank you

I have now padded my desk in anticipation...
