metric tapping

[buck30]

I am trying to program a M3X.5 tap.

 

I went to mill mm library and got the M3X.5 tap all good.

In the parameters tool Tab I filled in 500 RPM and the feed rate of 9.84252 came up,  also all good.

But the FPT seems stuck on .5,  ( Will not undate)no matter what values I put in anywhere.

Then whaen i post this, the F value comes out to 2.   after the G95.

 

Both very wrong. What am I doing wrong??????

 

 

 Thanks in advance for your help here guys.

Hi,

have you tried using F = the pitch of the thread M3 = 0.5 F = 0.5 soon, so I use a Fanuc 21 Series controller

Type .5mm in the FPT field and hit enter. 

[buck30]

when I type .5 in the FPT box the other numbers come up as .250 in the feedrate at 500 RPM

 

and when I post this the F is still 2.

 

It is asthough MC is seeing the FPT as .5 inch instead of .5mm????

But still don'y understand whey the posted code remains at 2.???

You need to leave the F= RPM * pitch or F= Pitch

Buck30,

 

Since it sounds like you're trying to metric tap in inch.....

 

Go into your tool definitions...is the "Metric Values" box still checked?  if so, uncheck it

 

I also just uploaded the other day metric taps converted to inch 1-30mm's, you might want to hunt that up and give it a shot

thats it Paris.  Now it is making sense and the code looks right.

 

My thinking was since i got the tap from the library the feed numbers would be there so it would work.

 

 

  Thanks again.
