Hello, newb here from Wi.
I just got a 94 VMC-15 running in Format 1.
I made this rigid tapping program on Unigraphics and used a Haas post.
Could any one help me edit this program to work on the Fadal with format1?
T8 is 8-32
T9 is 6-32
Any help will be greatly appricated!
Thanks,
Mark

I guess I could switch over to format 2 for my haas programs.

[msteckhan]

Ok,
Im switching to format 2 and running this,
Any one seeanny problems?????

Format 1 might work with, but doesn't need G43 or G49, the H word is all that is needed. And
H0 instead of a G49. Rigid tapping (if I remember correctly) uses some other G code before the G84.1 (rigid tap) is called. Also the machine must also support it to work. If you don't have a user manual you can down load it from http://www.fadalcnc.com/fadal_Tech_Docs1.htm .

The shop where I work has 12 Fadals, but only 2 or 3 of the machines support rigid tapping. So it isn't used unless we are short on compression expansion tap holders.

The spindle RPM and the feed must be the same.
The "Q" will convert the RPM to the proper feed.
It will tap into the part at a feedrate of F15.625


Example: S500 X Q.03125 = F15.625

Notice the R plan should be a minimum of .4 above. And notice the use M90, reference M93 high gain for rigid tape and M91 for normal milling.

[CAD/CAM Man]

Are you breaking taps? One thing I noticed is that your feed rate is rounded off. I would start by setting your post to output 4 decimal places for your tapping feedrate. I am not real familiar with format 1, but I would think that missing 0.0437 IPM could cause problems (pulled threads if the tap even survives).

*Canned cycles are active until canceled so you can continue to add locations with out calling up a new canned cycle. along with this you can change your R, Z, as needed.

*Calculating Feeds and Speeds Cad/Cam brings up a good point, I use Feed x Number of threads per inch = RPM, one can calculate for metric if you like. Thus F10. x 32 threads per inch = 320 RPM this will ensure rounding off numbers do not affect the thread profile or tap breakage.

*It has been awhile since I have ran a Fadal and this code may need to be slightly adjusted as to cancel of height offset.

This OP was asking about rigid tapping. G84 is for use with an extension/retraction tapping head. He needs to use G84.1 and the formating that goes with it.

[dpark1]

I use this everyday- 6-32 TAP

M6 T1
G0 G90 S160.1 M5
G84.2
X0 Y0 E1
Z.5 H1
G84.1 G98 R0+.4 Z-.5 S160.1 F5.
G80

The S160.1 comes from the pitch 32 (make 320/2=160,then add the .1)

I use this for all my taps, works fine.
