How do I add a G76 boring cycle to a post

[connormac]

I have a Kitamura post but it does not have a G76 boring cycle in it. I looked at mpmaster and tried to do it that way but just posted a G83 cycle.

I did a search but everything that came up seems to already have the cycle in the post and people just needed some advice.

I'm trying to bore the top of a hole then shoot thru and bore the bottom of the hole. I didn't want to write it log hand because I don't want to back bore all the way out.

Thanks in advance for any help.

How good are you with post editing?

[connormac]

Better that average.

You would have to use this cycle a lot to justify the time to set it up in the post.

Another option is to draw a line through C/L of holes and use 3D contour. Break the line where you need to change feed/G0, and use toolpath editor to modify.

Little bit of work on the toolpath, but everything is save with mcx file, and will post correctly with std post.

 

A problem using G76 is that you will not be able to feed straight through. It must retract to R for each bore.

Point toolpath works fine for me.

Got G76 to work in the post. Thanks all.

I think I'm going to have to do it the way Bryan suggest, to get the bottom bore. What is point tool path??

 

Thanks again!

Yes Bryan i was so happy I got the post to work with G76 till I figured out "CRAP" how do I get to the bottom bore.

Thanks Mastercam Guru. I figured point tool path and it did just what I needed. Thanks to all.
