Simple toolpath question for everyone but some modeling software...

Post by TSM2018 »

I am stumped.
I have a board with 1/2" depth of material.
I want to remove .25" of material surrounding the text.

A V Carve tool path makes sense, but I can't select an endmill, the software is saying NO, it V-Carve, therefore dumb user, you use a V-Carve Bit... Seems reasonable.

Remove material surrounding text.
ONLY Letters remain at .5" -- the depth of the board
Wish to remove material surrounding text.

Unable to Complete Basic task.

I've tried to select the boundary of the rectangle and the text...do I put the text in another boundary?

I am easily able to bring the letters down .25", but not able to remove material surrounding text.
Your help is most appreciated.

Someone always has to try and do the opposite of the norm. Sorry. I thought I had it solved and found my vcarve bits, but it did not work.

I eliminated all my trial tool paths. The modeling created of the letters is what I wanted.

Not sure I completely understand you, but looking at your file, if you select both the text AND the rectangle at the same time, I think you can accomplish what you want. A carving toolpath is definitely not the right tool for this.

There are a couple of ways to proceed.

1. If you want the look of a vcarve (see below) then use a v-carve toolpath with both the rectangle and letters selected. Check the "Flat Depth" checkbox, and set a flat depth of .25". It is also probably best to check "Use Flat Area Clearance Tool" and select some kind of end-mill to hog out the flat areas so that the v-carve bit won't have to remove as much material. It will look something like this (first picture is with a 90-degree v-bit and the second is a 60-degree v-bit)

2. You can also use a pocketing toolpath if you want straight sides on the letters. Similar process, but use end mills instead of a v-cutter. If I use a 1/8" end mill with a 1/4" clearance tool, it looks something like this (Note that there are run-together letters because they are too small for the 1/8 bit to clean up between the letters):

Another tool choice would be a 1-flute engraving cutter ie: 45° with a 0.020 or 0.030 flat at the tip. These cutters produce stunning results. Search for 'Stacked text' or Text on Text' for more info.
