lathe questions

[Mark C]

Hello all,

I have recently taken over much of the lathe programming here and have a few questions.

First of all how do you get MasterCam to allow feed rates of less than .002/IPR? I can't find any setting anywhere.

The next 2 involve the post processor. I'm customizing the Mplfan (v9) and it won't output a tooltable at the beginning of the program like a mill program will. I also want to include the tool nose rad in the tool comment, but can't figure out how to do it.

What i have done is include in the pwrttparam section is:

 

if prmcode = 20104, tnr = rpar(sparameter, 4)

 

and define the first 4 variables in line 20104.

all I'm getting is the ascii code for the insert type (the first # in line 20104) for the very last tool used only.

I've been through the post manual to get examples and looked at several mill and lathe posts, but info is spotty. How do I get the tnr to appear in my tnr variable and get a tool list at the beginning of the program?

Thank you in advance for any ideas

Go to line 3010 in your lathe post.

 

Change .002 to whatever minimum you want.

Dont forget to Save your setting.

 

3010. Minimum inch/revolution feedrate? .002

Duh!!

Didn't look there. I figured it was in the config

Thanks Bucket!!

You welcome Mark,

The funny thing is that I also wondered myself but was always too lazy to look.

The only time I really need a slower feed than .002 is for "parting off".

But when you asked,I had no choice but to look for an answer to help a fellow mastercam user.

Hi Mark,

I dont have a tool list in my nc code, however I made one in the setup sheet. I could not get it to print in here so I will email it

Mori.set

pwrtt #Write tool table Andy

#wrote 4 lines here for tool list

#7/01

If t>0, ptoolcomment #If the tool has

already been written

tool no. is neg.

ptoolcomment #Write tool info one line per pass

*"TOOL ", t," ", " R=",*tcr,"(",*strtoo

 

=",*tcr," (",*strtool,")", e

Andy,

That worked great.

I was able to put that in my post and output the tool list at beginning as well as write the tnr

 

Thank You
