Want to use G84 instead of G32

[cosres1997]

I'm using Mastercam 2021 with a a generic Haas TL 2 lathe post.  It uses a G32 tapping format and I want to convert it over to G84. Does anybody no what or how to change this in the post? I know were the canned tap cycle is in the post but have no idea what the G84 would look like.

This is the post for G32

Confused. G84 should be a milling cycle not a turning Cycle. If you want G84 then you will use a the Milling process to tap the hole with this post not the turning. Has HAAS changed the normal Thread Tapping with Lathe into normal Milling Thread Cycle?

Haas lathe also has G84 for rigid tapping.

Okay learned something.

Can either redefine the variable in here to G84 or create a new one and just call it. Odd after all the these years the Defauly 2X HAAS post is not using G84. I looked it up in the HAAS Lathe programming Manual and did find G84 for Peck Tapping on a HAAS 2 axis lathe.

Just to let you know that if you change this G32 to G84 here,

# --------------------------------------------------------------------------
# Select canned cycle type, profile is direction of finish profile vector
sthdg32 : "G32"      #Cycle type G32 <-- Change the G32 to G84
sthdg76 : "G76"      #Cycle type G76
sthdg92 : "G92"      #Cycle type G92
sthdg33 : "G32"      #Cycle type G32 with alternating position
sthdgcode : ""       #Target string

fstrsel sthdg32 thdtype$ sthdgcode 4 -1

it will change the single point thread cycle (long hand) to G84 and not effect the tapping cycle at all. The code that I originally sent is were it needs to be changed. Over time, I have successfully made changes to the code G32 tapping to use the G84 canned tap cycle. I'm amazed that there is no information on any forum about this exact subject. This was a trial and error process. You were the only response I had on the subject from 2 different forums.

your reseller can handle this change. I personally don't like the TL posts. I don't like having one machine programmed different from all the other machines. I just use the Generic Haas ST post instead. Works great.

Most users end up going to their Mastercam Reseller, who just makes the necessary edits to fix the output.

I'm glad you got your Post edited, and the code coming out correctly.

Ron was mentioning that you can change the "string variable" output string, to get "G84" instead of "G32". I know you still have to make other edits in 'ltap$' post block, but it will also depend on if you are using a "Lathe Tap Tool Definition" (goes through 'ltap$' Post Block), or a "Mill Tap Tool Definition", which should be going through "mtap$'. Depending on the type of Lathe/Mill Op you are using, there are multiple places to edit inside a Mastercam Lathe Post.

I have tried to use my reseller and made several attempts to contact them. They have left me high and dry so I'm on my own. On the bright side, it has taught me to be self reliant. Thanks for your reply.
