Rigid tap help.

[msteckhan]

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.

Here is how I do it in format 1

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

N55 G84.1 G99 R0+.4 Z-.3 S2000.2 F100. X0 Y0
The user manual format 2 example:

N57 G80

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.
