• #### Ballnose Cut Depth Musings for Feeds and Speeds in G

Simply put the cutting edges get less access to coolant and air for cooling and it is harder for them to drag the chips up and out of the way. Hence we penalize surface speedand chip load. Here again the definition makes sense given that we re making chips all along the full distance (radius of the ball).
