I have to increase the volume on a part that we make. I could get into all of it but I really just have a few questions about boring as I am still gaining experience in the cnc world. Number one, what are the pros and cons of boring out back to front, instead of front to back? When would that be practically applied? Do I need a special boring bar for it? If I don't ( and this might seem like a silly question but I just want to be sure) do I have to change the rotation of the spindle as opposed to when I do it front to back?
