Hello
I use BobCad 17 , I want use my CNC machine to engrave large inlay

(I want engrave my own cue logo)

but I meet a question , when I draw large logo with BobCad 17 ,
the cue can not rotate automatic

some one told me , I must use CNC program to do this... and others
told me that , BobCad 17 do not support this function

have anyone know , how can I do ? thanks:)
 
It is possible with Bobcad 17 to swap your rotational axis with your X or Y axis so that your depth remains constant for engraving, etc.
Your question is somewhat vague, so my answer might not be what you are looking for.

Sen-Ming...I have the formula for you if you wait until Monday. You actually exchange the A axis and the Y axis so the cue rotates, when it is supposed to move on the Y axis. As I promised, I will get you the calculations to do this on different diameters.

What method did you use to get the radius on the underside of the male piece? I considered doing something like that by cutting the contours in round stock, then boring it out until you could knock the pieces out of there. You could even translate the toolpath onto a cylinder to get the depth right with that method, and avoid swapping axes.

Sheldon - You are correct... I just inlayed the same diameter piece, and bored the piece out to snap in place.

Very cool! I might have to experiment with that someday... :)

Let me know if you have questions once you try it. After doing some, I think if you wrap the piece before you bore it out, you will have better success. I am going to try Blue tape next time, so when you bore the piece, it will not catch on the inlay cut, and break or chip the inlay.
