changing x values during posting

[Mark O. Anderson]

We have around 30 VMC so we have multiple seats of MASTERCAM mill. We have only one Lathe with "C" Axis capability so currently we do not own a Lathe version.

We occasionaly need to Live Tool a involved shape with the "C" axis on our lathe. We use our Mill software to out put the TXT so we can have the coordinate values.

We then need to double the "X" values to represent Diameter. and then change the "Y" word address to "C" word address.  The "Y" / "C" is an easy find/ replace.

Is there a way that I can alter the Post to double the "X" Values..............so I do not have to manually edit the "X".

 

Thanks for any help you can provide

Yes you could do that. All Lathe posts have the logic in them already. All generic post install with the product,. Open the generic Lathe post and borrow some logic form it and you should be good to go.

This is super easy to do. Just use a global formula at the top of your post.

 

Go below the variable formatting and initializations. I'd recommend just above "pheader$". Press enter a couple times to give yourself some blank lines above 'pheader$'. Starting in the first column of your text editor, enter this global formula: "xabs = xabs * two". Enter that on a line by itself, starting in the first column. That is what "tells" MP that the formula is "Global", and not just part of an existing post block.

ptime           #Convert 24-hour time format into 12-hour AM/PM format
      if time$ >= 13, time2 = (time$ - 12)
      else, time2 = time$
      hour = int(time2), min = frac(time2)
      *hour, ":", *min,
      if time$ > 12, " PM"
      else, " AM"

#Global Formula to "double" X coordinate output value.
xabs = xabs * two

pheader$         #Call before start of file                         
      if subs_before, " ", e$ #header character is output from peof when subs are output before main
      else, "%", e$
      sav_spc = spaces$
      spaces$ = 0

In my days I used Mplmaster post to program C axis. Mplmaster posts can do anything you want to do on your lathes.

Thanks for the input:

 

Colin:

I added the into my Post.

 

xabs = xabs * two

Just before the

 

pheader$

 

When I reposted, the X values are 4X

so I experimented and found that if I used the Square Root of two ( 1.414213 ) in place of the word two

The X Values posted as DOULBLE

This of course confuses my Norwegian Logic, can anyone explain this, so it makes sense to me ?

 

I have not found a Lathe Post yet, since this * two was intriguing me, but I will also continue in that direction.

 

Thanks for the Help
