Newbie- G84 CANNED TAPPING CYCLE

[mmussack]

Greetings all-

Ok.... so I'm trying to get MasterCAM X2 to post the right commands to do a simple RH tap.

To make a long story short, my boss gave the contact info for Thermwood (who writes our post procesors for MCX2) and they sent me a post that outputs a G84 command, which our machine does not recognize.

Does anyone know how to load such a canned cycle onto a router or to get MasterCAM to post an M04 command at the bottom of a Z plunge?

I will have check my thermwood post later when I get home. I do not remeber what they ask for.
Do you have sample code?

[mmussack]

This is a portion of the code that is supposed to do the tapping. When my machine gets to the G84 line, it locks up and says "Unknown Command".

% 1/4-20 UNC TAP

( Tool Change Call )

So you do not know the proper output for your machine? you are showing me that this does not work but what is the proper code for the machine.

take the X and Y comands out of the G84 line and try it again.

Also you have no safety line and no fixture offset call..........back to school with you

Maybe if I go back to school they will teach me to spell!

check your machine manual and see if you are exceeding the maximum rpm for tapping.
on one of my macines the tapping is not to go over 400 rpm.

just a thought

Get your software serial number from the control and call Thermwood. They can tell you if your version actually has a tapping function. The format looks good, but if the control says it not a valid command, it probably does not do tapping.

I'll take a look at my Thermwood tapping notes and see what I have also.

Well, since Thermwood wrote the post for this, I would have assumed they would know if it did tapping or not. My boss (who suggested I call Thermwood for this post) now says he doesn't think it was set up for drilling cycles.
