Rigid Tapping Question

[RJS100]

Thanks... I will give those setting a try. Just curious, have you had any luck with form taps or am I better off starting with a something simpler.

Is there a particular brand that you think are good for home shop use?

The video I showed you is with forming.

Forming will not work in all materials, must be with >15% elongation at break.

Predrilling needs to be bigger than for thread cutting, follow manufactures recommendations.

I would first verify that rigid tapping is working correctly by using Intercon. When all of the rigid tapping parameters are set correctly and verified with Intercon, then try it with F360.

Thanks for the nice information on taps. I will call one of the tool suppliers and get some taps ordered. Good idea to try Intercon.

Just to clarify on the Rigid tapping settings.

"My settings with Servo set to 0.2 s acceleration.

Try 0.5s Spindle Accel/Decel Time first in the Wizard

You can do some air tapping to watch if it seems to work.

Uwe

You are referring to parameter P04-14 for the servo acceleration of .2 seconds. Corrrects?

Richard

P04-14 and -15 both are set in ms.

I changed those parameters and tapped in the air. Everything worked perfectly.

I even changed the dwell time to zero (which caused errors before) on the tapping tool path and no matter what I do... It just works correctly. I have not been able to make it error out yet.

I noticed that you had a min. tapping speed of 800 rpm, should I use that instead of 640 rpm?

As soon as I get the correct machine taps... I'l try it again.

OK... I spoke to soon. I ran the same routine that taps three holes repeatedly. On the first run, it would dwell for 3 seconds on the 1st hole, but not the 2nd or 3rd. Run the program again, and it did not dwell on the first hole. There is definitely an error where some variables are not being reset properly.

I just created my first Intercom routine to test the rigid tapping. I am experiencing the same problems I was having with the g-code created with Fusion.

The first time I run the g-code, the tap comes to the top of the part and returns without tapping. The next time I run the same code, the tap taps down to .700 inches as programmed.

All of my rigid tapping parameters match the base line tapping parameters in the Centroid tech bulletin except P37 which is set to .5 instead of 3 -7.

I have attached the Intercon file below.

Here is a video illustrating:
