fadal programing question

[rgollar]

My question is if I use the M94.2 in my programs do I have to cancel them at the end of the program to go back to my defaults. And is the example below the proper way to do in the program? Thanks

 

1) Along with the M94.2

a. The R1+# represents the Deceleration value.

b. The P# represents the Acceleration value.

c. The Q# represents the Detail value.

2) Along with the M90 the P# represents the Gain value.

3) The F word in the program will establish the feed rate.

EXAMPLE: M6 T1

(TOOL #1, 1 INCH ROUGH EM 3FL

G0 G90 G8 S12000 M3 E1 X-.6 Y-.5

H1 Z-.5

G4 P1000

M94.2 R1+40. P10. Q.01

M90 P120.

F120.

Machine Setup 1) From the command mode, type SETP and press the ENTER button.

2) Press the space bar to the second page of the SETP menu.

a. Cursor over to BINARY BUFFERS.

b. Select 1) 15

Doing this reduces the look-ahead buffer. When altering the AFF parameters

on-the-fly, the changes become effective almost while the changes occur.

Suggested AFF

Settings

Rough Cuts: 1) To use this setting, program with at least .005 stock on all surfaces.

2) Gain—100, Deceleration—400, Acceleration—10, Detail—.005

Semi-Finish Cuts: 1) To use this setting, program at least .002 stock on all surfaces.

2) Gain—100, Deceleration—400, Acceleration—10, Detail—.002

Finish Cuts: 1) To use this setting, program with at least .0001 surface tolerance.

2) Gain—100, Deceleration—400, Acceleration—10, Detail—.0002

not to sound like a jerk but what are you trying to do that is that fussy on a fadal? i run 12 of them and they are not high speed nice finish machines

i have done tons of surfacing it works great but if you want a nice finish also forget it. just my 2 cents

[rgollar]

I do alot of surfacing and yes the fadal not the best machine for that but it works. I just was wondering if these settings would allow me to rough maching surface faster. As they dont have to be perfect just when I do the finish surfacing. But after playing with the arc filters I found that helped the most. I cant believe have it ran so much smoother and the file size is 80% smaller.

G8 FTW! You won't get any faster than that. Makes G0 look like a turtle.

[rgollar]

 

Do you replace all G0 with G8?

[McLaren]

No, just put a G8 right after the toolchange for the roughing endmill, then a G9 after the toolchange for the finishing endmill.

 

G8 is feedramps off, G9 is feedramps on. As a test you can write 3 programs like this:

Post back with the cycle times of each one.

Edit: I got rid of the safety lines. You shouldn't need em.

[rgollar]

Thank you so much Mclaren. The first program was 22 seconds. The second was 18 seconds. And the third was just wow it was 6.5 seconds. Thanks a ton thats what I was looking for in a roughing cycle where tolerance does not matter.

[McLaren]

ROFL. Yeah, people can talk all the smack they want about fadals, but I doubt there's any other machine out there that can do that in under 7 seconds. Plus you gotta love having a keyboard that's laid out qwerty style.

[rgollar]

Now if only the had a G-code to make the tool change faster lol.

I beg to differ. I've been using a Fadal 4020 with a Fanuc 18i-MB5 control as well as older Fadal machines with 32-MP and 88-HS controls. It (Fadal w/ Fanuc) is no barn burner like the Mazak Nexus sitting next to it or the Roku-Roku sitting behind it, but I've done more than a fair share of surfacing jobs on injection mold cavities that needed nothing more than some scrubbing with a bit of Scotch-Brite to finish them up.

 

But what's it matter anyway? There's nothing wrong with trying to eek the most out of what you already have.
