Changing the Toolpath to adjust for bit cutting length

[nichole42]

I am trying to make a hole in a piece of wood. The bit has a 17mm (0.66 inch) cut length but the hole needs to be 0.85". The issue is that the 2D adaptive toolpath is drilling down to depth and then making large circles from there. What happens is that by this time, the bit is deeper than the cutting length, so the top of the bit acts as a bearing (like on a router pattern bit). What I need is some way to tell it to work totally top to bottom. It needs to cut out the entire hole, then move a little deeper, then move a little deeper, until the hole is complete.  Is there a way to do that? Thank you

Please attach your model you are having issues.  This will supply the manufacturing tool as well.

Here you go. I hope I attached this correctly.

See if the attached file works for you.

Thank you! So if I understand correctly, there is no way to do what I was suggesting? I just have to program 2 consecutive operations where one goes x deep, and the next one starts there and goes the final depth?

I do not think your idea is possible in one operation because of the logic of the program.  Using the two programming operations is basically doing what you are suggesting but adapting it to the logic of the program.  Thanks for the Accepted Solution!
