for a cnc toolholder? Since mills can index their heads pretty damn accurately these days, I was wondering if a right angle toolholder could be usefull. Or better yet, one that can be tilted on a specific degree.
technically you could mill around something, indexing the head keeping it perpendicular to the cut? 4 axis cam could do the math. Simply exchange axis names in the post. Possibly reverse the numbers on the index, since the spindle will be indexing vs the 4th axis, or part.
