Need Help!- machining block letters

[chaz6966]

i have sunk block letters into a solid .012 deep for a logo.
some are .031 wide some are .125 wide(larger size).
whats the best way or toolpath to machine them in bobcad.
do i have to pick each one individually and machine one at a time.
my toolpath crashes through the solid to the next letter. on some of them.
z level finish v22.

the block letters were extracted from the solid to leave an impression in the block for depth of detail.

If the letters are flat on the bottom, then the best bet would be to do a pocket for these letters.

If you are running v22 you will want to create a pocket feature for every letter as to control the machine order.

V23 you would only need one pocket feature because you can optimize the tool path between pockets - in other words have it cut in a logical order -

If you are having an issue with the Z level I would check the solid.

But you really wouldn't want to run a Z level anyway because you'll have a really hard time ( with out editing the code ) to get the software to cut at the bottom of the surface. Not sure for Z level finish but the rough will not cut at the bottom of a surface it's always just a little bit off.


Example if you had a pocket in a solid that z's position was Z-1.26 or something like that. The Z level rough will not cut to Z-1.26. You would think you could just take that depth a divide by number of passes and have it finish that bottom surface, but nope that doesn't work it still off.

So in order to finish a flat you need to run a 2D pocket for finishing.
