Alignment problem
« on: November 14, 2007, 08:32:44 AM »
Am taking this opportunity to attach a file that I can't seem to get to align properly.
You will see that the bottom most rout is not aligned with the upper 12 routs.  Or
vice-a-versa - the top 12 are not aligned with the bottom one.  Whatever.
Would like help to get all aligned.

Thank you.

It is the way Mach draws the sub, the program will be ok.

Hi Graham,

I appreciate the quick reply and understand what your saying -
however, running the program/cutting a part, I get the mis-
alignment.  I'm sure it's in my code.

Thanks for your time and help,
Octavio

OK, I have had a 2nd look and the code needed a little adjustment at the start.

Hello Graham,

Yep, that did it.  Thank you.

One last question on this part program -
From the display you see that the .062" router bit
cuts interlocking (?) combs.  The problem is when
you actually rout the part the tip dimension of the
teeth are not the same.  They differ by approximately
.020".

Can cutter compensation be used to correct this?
And if so - how?

Thanks,
Octavio

If some are correct and some are wrong then it is a program fault or cutter push, this can not be compensated for using cutter comp as the comp is applied all over the part(s)

Try changing the feed rates and/or the order in which the cuts are done.  You may need to leave tabs at the end of the combs and take them out last.

Thank you Graham for your help.

Changed the part program - was easier than I had anticipated.
