How do you solve the blade with a knife blade
Not the machine tool ask, this is the knife phenomenon that the processing time, is objective existence
This is not the problem of machine tool, it is the processing resistance that causes the knife (when the resistance is removed and the blade of the knife is removed).
Don't step back from the path, but exit first and then return to the starting point. In this way, it increases the quality of the processed surface while protecting the cutter from the damage.
