The great Ted Williams once said, “Hitting a baseball is the hardest thing to do in sports.” If you don’t know about Ted Williams, he was in real life what John Wayne played in the movies.
Centrally hitting a round ball with a round bat, a ball traveling at various speeds, angles, and different spin rates, is hard enough. But the sweet spot on the bat is only about two ball diameters wide. If you are slightly off radially or axially you hit a weak ground ball or pop the ball up. Fail.
We contend, “Milling is the hardest thing to do in metalworking”.
Milling is a flexible bundle of helical teeth at the end of a cantilever beam, spinning at a high velocity, digging into and exiting a workpiece at different depths of cut while traveling in various directions. The sweet spot in milling is getting each tooth to cut at the same chip thickness with each revolution of the tool, all while dealing with all of the above conditions. Hard indeed.
FYI – 50 years ago, Ted Williams wrote the still state-of-the-art book on the subject called “The Science of Hitting”. And yes as shown below, you can tap-test bats as well as milling tools.
Sharing information about high performance milling technologies, the result of 30 years of research.
