Non-Canned Rigid Tapping

[robk]

How can I program a (rigid) tapping cycle without it being a canned cycle? Basically I am looking for point-to-point method for tapping. Is it as simple as I think it is by stopping the spindle and reversing it on the way out? Never done it like that (yet).

 

I am using tool tip point control and was told that canned cycles are not supported. Not sure if that's true, but for now I can't check it on the machine.

I believe that you have to use canned cycles for rigid tapping. Otherwise machine spindle wouldn't be synchronized with machine movement. Would like to know if I'm wrong on this.

I agree with doyleg.

 

You could tap using a floating head using a G01 but the I "think" the syncro would require a canned cycle.

The floating tap holder and programming the z (I assume) axis feed in IPR might work also.

Just use a G32 command, this will syncro the spindle. Just put in the m29 rigid tap call out.

program like this

just wondering what is "M1" and "S1" represent? on all our machines M1 is opt stop

[Hardmill]

Just make sure you close the door when you run it

 

 

PEACE

we have 3 spindle on that machine

M1= spinldle 1 on m1=3 same as m3

and spindele 1 speed= 40 same as s40

Thanks for all the suggestions. I wasn't able to make it work using tool tip programming (G43.4) so I had to go back and use a canned cycle for rigid peck tapping using a standard G43 TLO code and use G68 Coordinate rotation to get the desired results. Definitely not the way I want to do this in the future especially when the angles get funky;
