Tapping

[machinedudester]

I am trying to do 5 axis tapping with a tapping collet, a Rego-Fix ET1 with axial compensation. here is the recommendation:

Fast approach, then feed the tap with approximatively 95% of the pitch value, which uses 20-30% of the compensation stroke when the spindle rotation and the feed movement are simultaneously reversed.

Return feed must be made with 100% of the pitch, which maintains the sleeve of the collet in the compensation stroke up to the tap disengagement.

 

I am using a Haas controller with rigid tapping. Can I do this in Mastercam, or do I need to put the code in manually?

 

OK I got the code, I edited it manually.

 

Now can anyone suggest a good rpm for form tapping a 10-24 blind hole in 6061-T6 without breaking the tap???

 

I guess I will answer my own questions this time.

 

The manufacturer recommends 50-90 sfm or 1000-1800 rpm for a 10-24 unc with a 25%-50% reduction in blind holes.

 

Thank me! LOL
