Can somebody give me an example line of code for a typical tapping cycle for a Mazak M32 controller? I'm using the same G-code as an M2 controller (which tapping works perfectly) and here is what happens:

1) Machine spindle starts at programmed speed
2) Machine locates to correct X-Y location
3) Machine rapids in Z to the clearance plane
4) The spindle stops
5) the machine feeds in Z- and smashes the tap

I don't know if something is wrong with the machine or maybe the G84 code is different that the M2 controller G84.

Any help would be appreciated......

Thanks...Your code reacts the same way. It looks like the tapping cycle is broken. As a work-around, I will manually program the tapping cycle.

Once I program the full depth of the tap, what is the G-Code for a "pause" command (before I reverse the spindle)? I am using a floating tap holder in the spindle.

Thanks again....

I thought I should add some sample code to to clarify what I am after. I want to pause the CNC machine for 1 second after issuing the "spindle off" command before I reverse the spindle and retract Z.....I just need to know what the syntax is to "pause" my program for 1 second (I can adjust it later if needed).

Thanks

MrMazak.....Is that "G94" supposed to be a "G98" in your reply? I've been browsing the forums and found another person using G98? Although, I have no idea what G94 or G98 do!

Thanks for your reply.....much appreciated!

G94=TIME
G95=Spindle revolutions

G84 is for RIGID tap and you are using a FLOATING holder? Can you say SNAP!

Try using G32 cycle

[MrMazak]

G84 can be used for both types of tapping (H0=float H1=rigid). G84.2 (3) is always rigid tapping But the bigger question is why use a floating holder? That is likely the cause of all your troubles.
